[ CHEERS AND APPLAUSE ] Jason Titus: HI, EVERYONE.
I'M JASON, AND I RUN OUR DEVELOPER
PRODUCT GROUP HERE AT GOOGLE. AND IT IS SO GREAT TO BE BACK
AT SHORELINE AGAIN THIS YEAR. AND
FOR THOSE OF YOU JOINING OUR VIA
400 I/O EXTENDED SESSIONS ACROSS
85 COUNTRIES AS WELL AS YOU JOINING OVER THE LIVESTREAM,
THANK YOU AND WELCOME.
EARLIER SUNDAR TALKED ABOUT OUR VARIOUS BILLION-USER PLATFORMS. AND WHETHER IT'S ANDROID OR THE
WEB THROUGH CHROME, OUR SUCCESS HERE WOULD NOT BE POSSIBLE
WITHOUT YOU.

SO WE'RE GOING TO SPEND THE NEXT HALF AN HOUR
DIVING DEEP INTO OUR EXACTLY WHAT WE'RE DOING FOR ALL OF
YOU, THE DEVELOPERS WHO BUILD ON OUR
PLATFORMS EVERY DAY. [ CHEERS AND APPLAUSE ]
AND NO MATTER WHAT PLATFORM YOU'RE BUILDING ON, OUR GOAL IS
TO MAKE YOUR JOB EASIER AND ALLOW YOU TO FOCUS ON THE
PROBLEM YOU'RE TRYING TO SOLVE BY MINIMIZING THE PAIN POINTS
OF BUILDING A PRODUCT.
WE WANT TO SIMPLIFY REPETITIVE TASKS, WHETHER THAT MEANS
DEALING WITH USER LOGIN OR INSTRUMENTING ANALYTICS OR INC.
SYNCHRONIZING REALTIME DATA, WE WANT TO GIVE YOU THE TOOLS TO
MAKE IT EASY FOR YOU TO SOLVE EVERYDAY PROBLEMS IN SIMPLE AND
POWERFUL WAYS, AS WELL AS CREATE
ENTIRELY NEW PRODUCTS USING TECHNOLOGIES LIKE MACHINE
LEARNING AND VR AND VOICE-ENABLED INTERACTIONS.
IT IS IMPORTANT TO US THAT YOU ARE SUCCESSFUL. SO IN ADDITION
TO BEING — BUILDING PRODUCTS THAT HELP YOU BUILD YOUR APPS,
WE ARE ALSO ON THE GROUND IN OVER 130 COUNTRIES WITH
PROGRAMS LIKE WOMEN TECH MAKERS AND THE
GOOGLE DEVELOPER GROUPS.

[ CHEERS AND APPLAUSE ]
MANY OF WHOM ARE HERE TODAY. (CHANTING). SO I BELIEVE WE HAVE GDDs FROM
79 COUNTRIES HERE TODAY. SO THAT'S PRETTY EXCITING.
[ CHEERS AND APPLAUSE ] SO WE'RE ALSO INVESTING IN
TRAINING PROGRAMS, LIKE GOOGLE DEVELOPER CERTIFICATIONS AND
COURSES THROUGH UDACITY AND OTHER PARTNERS TO HELP YOU
DEEPEN YOUR TECHNOLOGICAL CAPABILITIES.
AND FROM THIS WORK AROUND THE WORLD, WE'RE SEEING FIRSTHAND
THAT DEVELOPERS ARE AT THE FOREFRONT OF TECHNOLOGICAL AND
CHANGE INNOVATION. WE SEE YOU SOLVING CHALLENGING
PROBLEMS IN WAYS THAT COULD NOT BE DONE BEFORE. FOR EXAMPLE,
LAST YEAR ON A TRIP TO INDONESIA, I MET GIBRAN
HUZAIFAH HUZAIFAH. HAVING WATCHED
AQUACULTURE BECOME AN INCREASINGLY IMPORTANT PART OF
HIS COUNTRY'S ECONOMY, HE LEFT A
CAREER IN BIOLOGY TO BECOME ONE OF THE NATION'S 3.5 BILLION
FISH FARMERS. WHAT HE FOUND WAS A
400-YEAR-OLD TRADE THAT WAS MIRED IN INEFFICIENCY WHERE
FARMERS WERE FREQUENTLY OVER OR UNDERFEEDING THEIR FISH. WITH
HIS CO-FOUNDER MUHAMMAD, THEY DECIDED THEY COULD HELP AND
THEY STARTED eFISHRY WHICH PROVIDES
A SMART AUTOMATED FISH FEEDER WHICH CAN SENSE WHEN FISH ARE
HUNGRY AND FEED THEM.

AS A RESULT THEY CAN SAVE THE
FARMERS UP TO 20% OF THEIR ANNUAL COST
AS WELL AS REDUCING HARMFUL ENVIRONMENTAL RUN-OFF. AND
THIS IS JUST ONE OF MANY STORIES OF
HOW OUR GLOBAL DEVELOPER COMMUNITY IS MAKING AN IMPACT
IN UNEXPECTED WAYS.
NOW, I WOULD LIKE TO BRING UP SOME COLLEAGUES TO GIVE UPDATES
ACROSS OUR DEVELOPER PLATFORMS. WE'RE
DOING TO MAKE ANDROID DEVELOPMENT EASIER. PLEASE
WELCOME STEPH.

[ CHEERS AND APPLAUSE ] Stephanie Saad Cuthbertson: AS
SUNDAR AND DAVE SAID, WITH 2 BILLION ACTIVE DEVICES ON
ANDROID AND 82 BILLION APPS INSTALLED FROM PLAY, ANDROID'S
MOMENTUM IS AMAZING. WHAT I LIKE EVEN MORE IS HOW ANDROID'S
MOMENTUM IS MAKING SO MANY DEVELOPERS SUCCESSFUL. THE
NUMBER OF DEVELOPERS WITH OVER A
MILLION INSTALLS GREW 35% JUST IN THE PAST YEAR. AND WE'RE
MAKING IT EASIER TO GROW REVENUE, TOO. IN ADDITION TO
CREDIT CARDS, GIFT CARDS, EVERYTHING ELSE, WE'VE EXPANDED
DIRECT CARRIER BILLING TO REACH 900 MILLION DEVICES WITH 140
OPERATORS. ALTOGETHER, THE NUMBER OF PEOPLE BUYING ON PLAY
GREW BY ALMOST 30% IN THE PAST YEAR.
NOW, TO SUPPORT THIS VAST ECOSYSTEM, WE'RE WORKING HARD
TO HELP DEVELOPERS BUILD GREAT
APPS AT EVERY STAGE, WRITING YOUR
APP, TUNING, AND GROWING YOUR BUSINESS. TODAY, WE'LL WALK
THROUGH FOUR BIG THEMES. THE FIRST IS LANGUAGES.
[ CHEERS AND APPLAUSE ] NEXT IS MAKING ANDROID
DEVELOPMENT FASTER AND EASIER WITH THE IDE AND LIBRARIES.

THIRD, WE'LL SHOW YOU EVEN MORE TOOLS TO BUILDING HIGH-QUALITY
EXPERIENCES. FINALLY, WE WANT TO HELP YOU GROW AND REACH NEW
USERS, LEVERAGING ANDROID INSTANT APPS. SO LET'S GO
STRAIGHT IN. WE HAVE BEEN SO EXCITED TO
ANNOUNCE FIRST-CLASS SUPPORT FOR
KOTLIN. [ CHEERS AND APPLAUSE ] THIS STARTS NOW. IN ANDROID
STUDIO, KOTLIN SUPPORT IS NOW BUILT IN. WE'LL SUPPORT
BUILDING APPS WITH AS MUCH KOTLIN AS YOU WANT, FROM ZERO
TO 100%. NOW, ALL OF YOU OF WHO
AN SITTEN CODE IN KOTLIN KNOW WHY
WE DID THIS ALREADY. BUT FOR EVERYONE, WE DID IT BECAUSE
KOTLIN IS A BEAUTIFUL PROGRAMMING LANGUAGE. WE ASKED
ONE GOOGLER HOW HE FELT AFTER WRITING KOTLIN FOR A COUPLE OF
WEEKS. "WELL, I WOULD NEVER EMBARRASSED ADAM POWELL BY
USING HIS NAME ON STAGE, HE SAID, I
THINK I AM IN LOVE." [ LAUGHTER ]
SO MANY OF YOU TOLD ME KOTLIN MAKES PROGRAMMING FUN AGAIN,
WITH SO MANY WONDERFUL FEATURES LIKE YOU'RE GOING TO SEE HERE
AND TOR WILL SHOW YOU MORE IN JUST A MOMENT. AS DEVELOPERS,
LANGUAGES ARE THE TOOLS WE USE TO EXPRESS OUR THOUGHTS.

WITH
KOTLIN, THERE'S JUST SO MUCH LESS SYNTACTIC NOISE THAT
STANDS BETWEEN WHAT I WANT TO SAY AND
HOW I SAY IT. NOW, FOR THOSE OF YOU WHO ARE
WONDERING WHAT THIS MAY MEAN FOR
THE JAVA PROGRAMMING LANGUAGE AND CPU C+PLUS, WE ARENESS ENHANCING
OUR EXISTING LANGUAGES. FOR INSTANCE, IN ANDROID STUDIO,
JAVA 8 FEATURES ARE NOW DIRECTLY
SUPPORTED WITH THE JAVAC COMPILER. AND WE HAVE ADDED
MORE JAVA 8 LANGUAGE APIs IN O. SO IF YOU WISH, YOU CAN
IGNORE KOTLIN COMPLETELY AND YOUR EXISTING LANGUAGE SUPPORT
WILL KEEP GETTING BETTER. BUT…
[ APPLAUSE ] IF YOU CAN'T WAIT TO GET
STARTED WITH KOTLIN, IT IS INCREDIBLY
EASY. KOTLIN WORKS 100% WITH THE JAVA PROGRAMMING LANGUAGE,
WHICH MEANS IT IS COMPLETELY INTEROPERABLE. THAT MEANS YOU
CAN KEEP EVERY LINE OF CODE IN YOUR EXISTING PROJECT.

YOU CAN
SEAMLESSLY CALL FROM KOTLIN INTO
THE JAVA PROGRAMMING LANGUAGE AND BACK WHICH MEANS IT IS VERY
EASY TO GET STARTED. YOU CAN ADD AS LITTLE AS A SINGLE
KOTLIN CLASS.
ANOTHER REASON WHY KOTLIN IS SUCH AN AMAZING FIT FOR ANDROID
IS IT'S MATURE AND PRODUCT-READY. KOTLIN HAS BEEN
AROUND FOR FIVE YEARS, AND MAJOR
APPS LIKE FLIPBOARD, PINTEREST, SQUARE CASH, EXPEDIA, AND MORE
ARE ALL USING KOTLIN IN PRODUCTION. NOW, KOTLIN'S NOT
JUST A GREAT LANGUAGE.

IT HAS OUTSTANDING IDE SUPPORT. THE
TEAM THAT BROUGHT YOU KOTLIN IS THE SAME TEAM BEHIND INTELLIJ
WHICH AS YOU KNOW IS WHAT POWERS
ANDROID STUDIO, OUR IDE. FINALLY, ANDROID HAS COMMITTED
TO KOTLIN AS A FIRST-CLASS LANGUAGE AND AS YOU HEARD,
WE'RE ANNOUNCING OUR PLANS TO PARTNER
WITH JETBRAINS TO MOVE CLOTH INTO A NON-PROFIT FOUNDATION —
KOTLIN INTO A NON-PROFIT FOUNDATION. KOTLIN IS OPEN
SOURCED UNDER APACHE 2. WE LOVE
HOW IT FITS.AROUND OUR COMMUNITY. NOW TOR WOULD LOVE
TO SHOW YOU KOTLIN IN ACTION. SO, TOR.
[ CHEERS AND APPLAUSE ] Tor Norbye: THANKS, STEPH.
SO HERE'S A PRETTY TYPICAL DATA CLASS WITH THREE PROPERTIES
IMPLEMENTED IN JAVA. AS YOU CAN
SEE, THERE'S A LOT OF BOILERPLATE CODE HERE WITH
FIELDS, GETTERS, SET QUESTIONERS, HASH CODES,
ET CETERA. LET'S LOOK AT HOW WE
WOULD IMPLEMENT THIS IN KOTLIN. AND NOW I'M GOING TO WRITE THE
EQUIVALENT KOTLIN CODE. HERE'S THE FIRST LINE.
AND THAT IS ALSO THE LAST LINE. THIS CODE —
[ CHEERS AND APPLAUSE ] THIS CODE IS COMPLETELY
EQUIVALENT TO THE 87 LINES I JUST DELETED.

THE COMPILER
DOES ALL THE WORK. IT GENERATES THE
SAME CODE AS BEFORE PLUS SOME EXTRA GOODIES. SO FROM JAVA, I
CAN CALL INTO MY NEW KOTLIN CLASS AND ACCESS THE SAME
GETTERS AS BEFORE. BUT LOOK WHAT HAPPENS IN KOTLIN. HERE
WE HAVE A REALLY NICE PROPERTY
SYNTAX, SO I CAN, FOR EXAMPLE, USE ASSIGNMENT TO ASSIGN TO
THIS PROPERTY INSTEAD OF CALLING A
SETTER. NOW, AS YOU ARE STARTING OUT
WITH KOTLIN, YOU MIGHT FIND YOURSELF STUCK REALIZING YOU
DON'T KNOW HOW TO DO SOMETHING. IMAGE PROCESSING AND I REALIZE
THAT I DON'T KNOW HOW TO DECLARE
TWO-DIMENSIONAL ARRAY. WELL, WHAT I CAN DO IS OPEN UP A JAVA
FILE, WRITE THE CODE IN JAVA, WHICH I KNOW HOW TO DO, GO BACK
TO KOTLIN, AND LOOK WHAT HAPPENS
WHEN I PASTE.

THAT'S RIGHT, THE
IDE CONVERTS IT FOR ME. [ CHEERS AND APPLAUSE ] IT'S A HUGE HELP WHEN YOU'RE
STARTING OUT. SO AS STEPH CAN ATTEST, I CAN LITERALLY SET FOR
THREE HOURS AND TELL YOU ALL THE
THINGS I LOVE ABOUT KOTLIN. WE DON'T HAVE TIME FOR THEM.
INSTEAD I WOULD ENCOURAGE THEM ALL TO COME TO OUR EXCELLENT
TALKS ON FRIDAY WHERE YOU LEARN EVERYTHING YOU NEED TO KNOW TO
GET STARTED WITH KOTLIN. I HOPE
YOU WILL LOVE CODING IN KOTLIN AS MUCH AS I DO. Stephanie Saad Cuthbertson:
THANKS, TOR. [ CHEERS AND APPLAUSE ]
FOR US ON ANDROID, ADDING KOTLIN
FEELS LIKE A MOMENT IN HISTORY. WE'RE EXCITED TODAY. IT'S JUST
THE BEGINNING, THOUGH. WE'RE EVEN MORE EXCITED ABOUT THE
POSSIBILITIES THAT KOTLIN CREATES FOR THE FUTURE.
BUT THERE'S MORE.

OUR SECOND THEME IS MAKING
DEVELOPMENT FASTER AND EASIER WITH OUR TOOLS AND LIBRARIES.
ANDROID STUDIO'S OUR OFFICIAL IDE. IT IS PURPOSE-BUILT FOR
ANDROID. AND WE KEEP INCREASING
INVESTMENT. TODAY, WE'RE RELEASING ANDROID
STUDIO 3.0'S FIRST CANARY, FOCUSING ON SPEED AND SMARTS
AND ANDROID PLATFORM SUPPORT, PLUS
NEW LIBRARIES FOR APP ARCHITECTURE.
SO LET'S GO STRAIGHT TO A DEMO. THIS IS MORE FUN.
ALL RIGHT. SO HERE I HAVE ANDROID STUDIO 3.0. AND I'VE
JUST BUILT AND DEPLOYED MY APP. PROFILERS, CPU, MEMORY, AND
NETWORK. SO I'M JUST GOING TO OPEN THE
APP. AND LET ME DO A LITTLE BIT OF
NETWORK HERE SO YOU CAN SEE IT ON THE GRAPH.
WHAT YOU CAN SEE IS THE NETWORK PROFILER. AND IT'S REALLY COOL
THAT YOU CAN SEE ALL OF THE REQUESTS. BUT PARTICULARLY
COOL WOULD BE IF YOU COULD CLICK AND
SEE THE ACTUAL PAYLOAD OF THE REQUEST.
EVEN BETTER THAN THAT WOULD BE IF YOU COULD LOOK AND SEE THE
HEADERS. BUT I ACTUALLY THINK IT WOULD BE VERY COOL IF YOU
COULD CLICK ON THE CALL STACK AND SELECT AND GO TO THE LINE
OF CODE.
[ CHEERS AND APPLAUSE ] SO THOSE ARE THE THREE NEW
PROFILERS.

3.0 ALSO INCLUDES A PREVIEW FEATURE FOR DEBUGGING
ANY APK, SO YOU CAN BUILD IN ANY
IDE AND DEBUG IN ANDROID STUDIO,
INCLUDING USING THESE PROFILERS FOR JAVA CODE.
SO TO SAY MORE ON SPEED AND SMARTS, YOUR FEEDBACK HAS MADE
DRIVING DOWN SYNC AND BUILD TIME
OUR NUMBER-ONE PRIORITY. BENCHMARKING WITH A REAL-LIFE,
100-MODULE PROJECT SINCE 2.2, THE BUILD CONFIG TIME HAS
DROPPED FROM THREE MINUTES DOWN TO TWO SECONDS, AND WE WILL
KEEP WORKING ON BUILD SPEED.
ON THE EMULATORS, WE'VE ADDED PLAY STORE FOR END-TO-END
TESTING. AND THERE'S SO MUCH MORE HERE.
THE NEXT THING I WANT TO TALK ABOUT IS ANDROID PLATFORM
SUPPORT. YOU WILL FIND AWESOME FEATURES
FOR ANDROID AND O, LIKE END-TO-END INSTANT APPS
SUPPORT, O SYSTEM IMAGES, AND TONS OF
HELPER TOOLS.

FOR INSTANCE, DAVE TALKED ABOUT
ADAPTIVE ICONS, WHICH WE ALL NEED TO BUILD NOW. SO OUR TEAM
HAS BUILT TOOLS THAT MAKE THAT EASY.
AND ONE OF MY PERSONAL FAVORITE FEATURES IS TO DOWNLOAD ANDROID
DEPENDENCIES FOR BUILD, YOU DON'T HAVE TO GO THROUGH THE
ANDROID SDK MANAGER ANYMORE. WE'RE NOW DISTRIBUTING THROUGH
OUR OWN MAVEN REPOSITORY. [ CHEERS AND APPLAUSE ] FINALLY, YOU HAVE ASKED US TO
MAKE ANDROID FRAMEWORKS EASIER, LIKE PROVIDING AN OPINIONATED
GUIDE TO BEST PRACTICES OR A BETTER WAY OF DEALING WITH LIFE
CYCLES.

WE'RE LAUNCHING A PREVIEW OF
NEW ARCHITECTURE COMPONENTS,
LIBRARIES FOR COMMON TASKS. THIS STARTS WITH LIBRARIES FOR
THE VIEW MODEL PATTERN, DATA STORAGE, AND MANAGING ACTIVITY
AND FRAGMENT LIFE CYCLES. WE WOULD LOVE IF YOU WOULD
DOWNLOAD AND TRY ALL OF THIS TODAY.
NOW, AS WE MOVE FROM CODING OVER
INTO HOW TO TUNE YOUR QUALITY AND GROW, I'D LIKE YOU TO HEAR
FROM ELLIE POWERS. PLEASE WELCOME ELLIE.
THANK YOU. [ APPLAUSE ] Ellie Powers: THANK YOU,
STEFTDZ. AS ALL OF YOU KNOW, BUILDING A
SUCCESSFUL BUSINESS ON PLAY STARTS WITH A HIGH-QUALITY APP. AND YOU'VE TOLD US THAT
SOMETIMES YOU NEED TO TARGET THE
RIGHT DEVICES IN ORDER TO ENSURE
THE BEST USER EXPERIENCE. SO WE'RE MAKING IT EASIER TO
UNDERSTAND ANDROID'S DEVICES AND
TARGET THEM IN THE PLAY CONSOLE.
NOW YOU CAN BROWSE A DETAILED DEVICE CATALOGUE, NO MORE
SEARCHING FOR SPECS ONE DEVICE AT A TIME.
IF YOU NEED A CERTAIN AMOUNT OF RAM OR YOU HAVE A PROBLEM WITH
A SPECIFIC SYSTEM ON A CHIP, YOU
CAN NOW SET TARGETING RULES TO ADDRESS THAT.
BEFORE EXCLUDING DEVICES, YOU CAN EVEN SEE YOUR INSTALLS,
RATING, AND REVENUE PER DEVICE.

NOW, ENSURING QUALITY
EXPERIENCES REALLY MATTERS. THE
PLAY TEAM TOOK A SAMPLE OF APPS AND ANALYZED THE CORRELATION
BETWEEN APP QUALITY AND BUSINESS
SUCCESS. WHEN APPS MOVE FROM AVERAGE TO
GOOD QUALITY, WE SAW AN AMAZING SIXFOLD INCREASE IN SPEND, AND
A SEVEN HELPFOLD INCREASE IN
RETENTION. THAT IS PHENOMENAL. WE ARE ALWAYS LOOKING FOR NEW
WAYS TO BRING USERS TO YOUR APPS, AND INSTANT APPS IS OUR
BIG BET IN THIS AREA. LAST YEAR, WE PROVED ANDROID
INSTANT APPS. INSTANT APPS ALLOWS YOU TO EXPERIENCE
EVERYTHING YOU LOVE ABOUT APPS, BUT WITHOUT THE HURDLE OF
INSTALLATION. SINCE THEN, WE'VE BEEN WORKING
WITH PARTNERS TO REFINE THE PRODUCT. THEY HAVE LAUCHED 50
INSTANT APPS, FROM IMMERSIVE VIDEO WITH VIMEO TO MOBILE
COMMERCE WITH JET, TO APARTMENT-HUNTING WITH HOTPADS.
AND WHILE IT'S STILL EARLY DAYS,
DEVELOPERS ARE REPORTING POSITIVE RESULTS. FOR EXAMPLE,
JET, HOTPADS, AND VIMEO ARE SEEING DOUBLE-DIGIT INCREASES
IN PURCHASES, LEADS GENERATED, AND
VIDEOS WATCHED. SO TODAY, WE ARE OPENING UP
ANDROID INSTANT APPS TO ALL ANDROID DEVELOPERS. THIS MEANS
ANYONE — [ APPLAUSE ]
THANK YOU.

THIS MEANS ANYONE CAN NOW BUILD
AND PUBLISH AN INSTANT APP. FEEDBACK FROM OUR PARTNERS HAS
SHAPED THE DEVELOPMENT TOOLS THAT WE'RE MAKING AVAILABLE TO
ALL ANDROID DEVELOPERS TODAY. LET'S TAKE A LOOK.
YOU BUILD INSTANT APPS IN ANDROID STUDIO 3.0. MANY OF
YOU WONDERED IF BUILDING AN INSTANT
APP MEANS MAINTAINING TWO FORKS OF YOUR CODE; RIGHT?
THE ANSWER IS NO. YOU CAN USE EXACTLY THE SAME
CODE FOR YOUR INSTANT APP AND YOUR INSTALLABLE APP.
YOUR INSTANT APP IS DOWNLOADED AS NEEDED, FEATURE BY FEATURE.
SO YOU'LL ORGANIZE YOUR PROJECT INTO FEATURE MODULES AND THEN
USE THAT CODE IN BOTH YOUR INSTANT APP AND YOUR
INSTALLABLE APP.
NOW, WE KNOW REFACTORING YOUR APP INTO FEATURES CAN SOMETIMES
BE A BIT OF A PAIN, SO WE'RE PROVIDING TOOLS TO EASE THE
PROCESS. FOR EXAMPLE, THE NEW MODULIZED
REFACTORING ACTION HELPS YOU MOVE CODE AND RESOURCES BETWEEN
MODULES. EVERY APP IS DIFFERENT, BUT
WE'VE SEEN WITH OUR EARLY PARTNERS THAT INSTANT APP
DEVELOPMENT TYPICALLY TAKES ABOUT FOUR TO SIX WEEKS WITH
THE LATEST TOOLS.
AS YOU ALL KNOW, THE FASTER YOUR
PRODUCT IS, THE MORE USAGE YOU'LL GET.

SO YOU'LL WANT
EACH MODULE TO LOAD AS QUICKLY AS
POSSIBLE. WE'RE PROVIDING OPTIMIZATION TOOLS, FROM
SPACE-SAVING SHARED LIBRARIES, TO MORE EFFICIENT ASSET
DELIVERY, TO ON-THE-WIRE COMPRESSION.
AND WHEN YOU'RE READY, YOU'LL JUST UPLOAD YOUR INSTANT APP
APKs TOGETHER WITH YOUR INSTALLABLE APK IN THE PLAY
CONSOLE. IF YOU'RE GETTING READY TO
BUILD FOR ANDROID O, WE'RE
INTRODUCING NEW APIs AND BEHAVIORS FOR
INSTANT APPS. THERE'S A NEW, MORE EFFICIENT
RUNTIME SANDBOX, AND USERS WILL BE ABLE TO FIND INSTANT APPS
DIRECTLY IN THE LAUNCHER AND THEN ADD THEM TO THEIR HOME
SCREENS. LET'S LOOK AT AN EXAMPLE.
I HEARD ABOUT THE NEW YORK TIMES
CROSSWORD APP RECENTLY, AND I CAN SEARCH FOR IT IN THE
LAUNCHER AND THEN OPEN IT WITH A
SINGLE TAP.

I CAN EVEN DRAG IT TO THE HOME SCREEN, SO IT'S
EASY TO COME BACK LATER.
BY THE WAY, IN EARLY TESTING, THE TIMES IS SEEING
SIGNIFICANTLY MORE ENGAGEMENT FROM PEOPLE PLAYING AND
COMPLETING PUZZLES. TO GET STARTED BUILDING AN
INSTANT APP TODAY, GO TO G.CO/INSTANTAPPS, AND COME
VISIT US AT OUR I/O SESSIONS OR AT
THE ANDROID SANDBOX.
WITH ANDROID IN SO MANY PLACES, TYPES OF EXPERIENCES, LIKE THE
GOOGLE ASSISTANT, BRINGING GOOGLE'S INTELLIGENCE TO
BILLIONS OF PEOPLE. IT'S BEEN REALLY COOL TO SEE THE
ASSISTANT REALLY COMING TO LIFE AND
ROLLING OUT ON SO MANY DEVICES THIS YEAR.
NEXT UP, WE'LL LEARN WHAT THE GOOGLE ASSISTANT MEANS TO YOU
AS A DEVELOPER FROM BRAD ABRAMS.
THANK YOU. Brad Abrams: THANKS, ELLIE.
IN DECEMBER LAST YEAR WE LAUNCHED AN EARLY VERSION OF
THE ACTION ON GOOGLE DEVELOPER PLATFORM. THIS
VERSION LETS YOU BUILD APPS FOR GOOGLE HOME, BUT SINCE
THEN, WE'VE BEEN FOCUSED ON GROWING YOUR AUDIENCE,
EXPANDING THE PLATFORM FEATURE SET, AND IMPROVING
THE DEVELOPER EXPERIENCE. AS YOU HEARD IN THE KEYNOTE
THIS MORNING, YOUR APPS ARE NOW AVAILABLE TO GOOGLE
ASSISTANT USERS ACROSS ANDROID AND THE iPHONE.

AND AS WE CONTINUE TO EXPAND THE ASSISTANT'S REACH TO MORE
SURFACES, THE DEVELOPER PLATFORM WILL FOLLOW.
WITH APPS FOR THE ASSISTANT NOW AVAILABLE ON THE PHONE,
YOU'LL HAVE THE OPPORTUNITY TO GROW YOUR USER BASE, BUT
MORE IMPORTANTLY, YOU'LL BE ABLE TO BUILD APPS FOR
ENTIRELY NEW ASSISTIVE USE CASES, THINGS THAT PREVIOUSLY
WEREN'T WELL SUITED TO A VOICE-ONLY INTERFACE, SUCH AS
SHOPPING FOR CLOTHES OR ORDERING FOOD FROM A LENGTHY
MENU. IN ADDITION, WITH OUR NEW UI
ELEMENTS SUCH AS IMAGE CAROUSELS, LISTS, AND
SUGGESTION CHIPS, USERS CAN EASILY GET THINGS DONE WITH
YOUR APP. THEY CAN SEAMLESSLY TRANSITION BETWEEN
VOICE, TYPING, AND TAPS, ALL IN THE SAME CONVERSATION.
YOU CAN BUILD AND DEPLOY APPS FOR THE ASSISTANT ON THE
PHONE STARTING TODAY. [ CHEERING ]
THANK YOU.

WE ALSO WANT TO MAKE IT EASY
TO COMPLETE PURCHASES THROUGH THE ASSISTANT TO HELP YOU
GROW YOUR BUSINESS. WE DESIGNED THE TRANSACTION
EXPERIENCE ON THE ASSISTANT TO BE EASY AND LIGHTWEIGHT
FOR USERS AND DEVELOPERS ALIKE.
YOU HEARD ABOUT TRANSACTIONS THIS MORNING FROM VALERIE,
BUT LET ME EXPAND A LITTLE BIT FROM A DEVELOPER POINT OF
VIEW. FOR PAYMENTS, YOU CAN CHOOSE
TO USE GOOGLE-FACILITATED PAYMENTS WHICH ARE EASY TO
INTEGRATE, ALLOW YOU TO LEVERAGE HUNDREDS OF MILLIONS
OF CARDS THAT USERS HAVE ALREADY STORED WITH GOOGLE,
AND ARE AVAILABLE TO DEVELOPERS FOR FREE.
OR YOU CAN CHOOSE TO USE A PAYMENT METHOD THAT USERS
HAVE ALREADY PROVIDED YOU. TO DO SO, WE RECOMMEND USING
OUR NEW SEAMLESS ACCOUNT LINKING SUPPORT. THAT ALLOWS
USERS TO SIGN IN TO AN EXISTING ACCOUNT OR EVEN
CREATE A NEW ACCOUNT IN JUST TWO TAPS.
HOWEVER, THE TRANSACTION ISN'T OVER WHEN THE USER
PAYS.

USERS MAY WANT TO CHECK ON THE STATUS OF AN
ORDER, MODIFY AN ORDER, OR EVEN RE-ORDER AN ITEM.
THAT'S WHY THE ASSISTANT NOW ALLOWS USERS TO SEE ALL THEIR
TRANSACTIONS IN A SINGLE HISTORY VIEW.
FINALLY, WE BUILT A NEW ORDERS-UPDATE FEATURE TO
ALLOW USERS TO MAKE IT EASIER TO ENGAGE WITH YOUR APP. YOU
ARE NOW ABLE TO SEND STATUS UPDATES ASYNCHRONOUSLY FOR
EXAMPLE WHEN THEIR CAR ARRIVES OR A PRESCRIPTION IS
READY. YOU CAN BUILD AND TEST TRANSACTIONAL APPS TODAY
AND THEY'LL BE AVAILABLE TO GOOGLE ASSISTANT USERS ON THE
PHONE SOON. BUT WHAT GOOD ARE THESE
TRANSACTIONAL FEATURES IF USERS CAN'T DISCOVER YOUR
APP? TODAY WE'RE ROLLING OUT A NEW
APP DIRECTORY. USERS CAN ACCESS IT WITH A SINGLE TAP
FROM THE GOOGLE ASSISTANT. IT NOT ONLY HAS CATEGORIES
AND USER RATINGS, IT ALSO ALLOWS USERS TO TRY YOUR APP
RIGHT FROM THE DIRECTORY PAGE.
USERS CAN ALSO CREATE A SHORTCUT TO YOUR APP FOR AN
EASY WAY TO INVOKE IT.

FOR EXAMPLE, INSTEAD OF SAYING,
SAYING, "OKAY, GOOGLE, ASK FORE
CASTER JOE WHAT ELSE THE SURF REPORT FOR THE OUTER BANKS,"
YOU CAN JUST SAY YOUR SHORTCUT, "OKAY, GOOGLE, IS
THE SURF UP?" EACH APP'S DIRECTORY PAGE IS
ALSO SHAREABLE ON THE WEB SO THAT YOU CAN PROMOTE YOUR APP
TO NEW USERS AND YOUR EXISTING USERS CAN SHARE IT
WITH THEIR FRIENDS. AND TO MAKE FINDING YOUR APP
EASIER, THE ASSISTANT IS ALSO LEARNING FROM THE DIRECTORY
AND OTHER INFORMATION PROVIDED BY THE DEVELOPER.
THANKS TO THESE ADDITIONAL SIGNALS, THE ASSISTANT CAN
OFTEN PRESENT USERS WITH A FEW DIFFERENT OPTIONS FOR
GENERAL REQUESTS LIKE, "PLAY A GAME."
WHILE WE'RE CONFIDENT THESE FEATURES WILL HELP IMPROVE
DISCOVERABILITY OF YOUR APPS, OUR WORK IS NOT DONE.
IMPROVING DISCOVERABILITY IS IMPORTANT TO ALL OF US, AND
YOU CAN EXPECT ONGOING INVESTMENTS AND IMPROVEMENTS
IN THIS AREA.

WE'RE EQUALLY INVESTED IN
PROVIDING A GREAT DEVELOPER EXPERIENCE. TODAY, WE'RE
LAUNCHING A NEW DEVELOPER CONSOLE, THE ACTIONS CONSOLE
HELPS YOU WORK BETTER AS A TEAM, COLLECT DATA ABOUT YOUR
APP'S USAGE, PERFORMANCE AND DISCOVERY PATTERNS. THIS NEW CONSOLE IS WELL INTEGRATED
WITH FIREBASE AND THE GOOGLE CLOUD CONSOLE SO YOU CAN
EASILY SHARE DATA WITH YOUR APPS.
IN ADDITION TO THE BRAND-NEW CONSOLE, WE'RE ALSO PROVIDING
YOU ACCESS TO DEVELOPER TOOLS THAT LET YOU QUICKLY AND
EASILY BUILD APPS FOR THE ASSISTANT.
SINCE LAUNCHING OUR PLATFORM, WE'VE WORKED WITH AN
EXPANDING NUMBER OF DEVELOPER TOOLS COMPANIES TO MAKE THEIR
SOLUTIONS COMPATIBLE WITH ACTIONS ON GOOGLE. WE'RE
ALSO EXPANDING THE CAPABILITIES OF API.AI, OUR
OWN CONVERSATION BUILDING TOOL, LAUNCHING NEW FEATURES
SUCH AS FOLLOW-UP INTENTS, PREBUILT AGENTS, AND
IN-DIALOGUE ANALYTICS.

WHILE WE'RE STILL AT THE
EARLY DAYS OF THE ACTIONS ON GOOGLE PLATFORM, WE'RE
FOCUSED ON MAKING IT ROBUST AND EXPANDING ITS REACH AND
CAPABILITIES. WE'RE SOON LAUNCHING THE PLATFORM IN
U.K. ENGLISH WITH FRENCH AND FOLLOWING LATER THIS YEAR.
WE ALSO INTEND TO BRING THE PLATFORM TO MANY NEW DEVICES,
INCLUDING ALL THOSE POWERED BY THE GOOGLE ASSISTANT SDK.
WE'RE EXCITED ABOUT THE ROAD AHEAD, AND WE WANT MORE OF
YOU TO JOIN US BY DEVELOPING FOR THE PLATFORM. WITH AN
ADDRESSABLE AUDIENCE OF 100 MILLION DEVICES, NEW
CAPABILITIES LIKE TRANSACTIONS AND IMPROVED
DEVELOPER EXPERIENCE, WE THINK THIS IS AN INCREDIBLE
OPPORTUNITY FOR ALL OF US. YOU KNOW, THE MAGIC OF THE
ASSISTANT IS ENABLED BY GOOGLE'S DEEP INVESTMENTS IN
AI AND THE CLOUD. AND TO TELL YOU MORE ABOUT HOW YOU
CAN USE THAT DIRECTLY, PLEASE WELCOME FEI-FEI.
THANK YOU. [ APPLAUSE ]
Fei-Fei Lee: HI. I'M FEI-FEI LEE. I'M CHIEF
SCIENTIST OF AI AND MACHINE LEARNING AT GOOGLE CLOUD.
WHAT AN EXCITING DAY.

I'VE BEEN DOING AI RESEARCH
FOR ALMOST TWO DECADES, AND I CAN HONESTLY SAY THESE LAST
FEW YEARS HAVE BEEN THE MOST EXCITING OF MY ENTIRE CAREER.
AI IS TRANSFORMING EVERYTHING GOOGLE DOES. AND AS WE
SPEAK, INDUSTRIES FROM FINANCE TO HEALTHCARE ARE
AUGMENTING HUMAN CAPABILITIES WITH MACHINE INSIGHTS.
BUT BUILDING AI EXPERTISE IS A SIGNIFICANT INVESTMENT, AND
WE KNOW THAT MANY OF YOU SIMPLY HAVEN'T HAD THE
OPPORTUNITY.

I JOINED GOOGLE PRECISELY FOR
THIS REASON, TO ENSURE THAT EVERYONE CAN LEVERAGE AI TO
STAY COMPETITIVE AND SOLVE THE PROBLEMS THAT MATTER MOST
TO THEM. IN OTHER WORDS, WE'RE MEETING
YOU WHERE YOU ARE. WE CALL THIS DEMOCRATIZING AI. AND
I'D LIKE TO SHARE A FEW EXAMPLES IN ACTION.
FIRST, WE'RE DEVELOP- — DEMOCRATIZING THE ALGORITHMS
THAT MAKE AI SO POWERFUL, WITH A COLLECTION OF
HIGH-LEVEL MACHINE LEARNING APIs THAT CAN HELP YOUR
APPLICATIONS UNDERSTAND THE CONTENT OF IMAGES, VIDEOS,
AUDIOS, AND NATURAL LANGUAGE WITH MINIMAL EFFORTS.
WHATEVER YOUR LEVEL OF EXPERTISE, THESE ARE TOOLS
YOU CAN PUT TO USE IMMEDIATELY AND SEE RESULTS.
AT THE SAME TIME, WE'RE EQUALLY FOCUSED ON DEVELOPERS
READY TO BUILD THEIR OWN MODELS.
IN NOVEMBER 2015, GOOGLE OPEN SOURCED TENSORFLOW, A
SOFTWARE FRAMEWORK FOR MACHINE LEARNING THAT IS USED
EXTENSIVELY THROUGHOUT GOOGLE.

TODAY, WE'RE
CONTINUING THE EVOLUTION BY BRINGING NEW HIGH-LEVEL
APIs IN TENSORFLOW 1.2 THAT MAKES IT EASIER FOR YOU TO
START TRAINING MACHINE LEARNING MODELS ON YOUR DATA
RIGHT AWAY USING THE BEST HARDWARE YOU HAVE AVAILABLE.
I ENCOURAGE YOU TO CHECK OUT OUR TENSORFLOW SESSIONS TO
LEARN MORE. ADDITIONALLY, WE ALSO
LAUNCHED THE CLOUD MACHINE LEARNING ENGINE TO HELP YOU
MANAGE LARGE-SCALE TENSORFLOW TRAINING AND PREDICTION JOBS
IN THE CLOUD.
OF COURSE OF THERE'S NO GETTING
AROUND THE FACT THAT AI REQUIRES ENORMOUS
COMPUTATIONAL RESOURCES, AND THIS REPRESENTS ONE OF THE
STEEPEST BARRIERS TO ENTRY FOR DEVELOPERS. TO ADDRESS
THIS, SUNDAR ANNOUNCED THIS MORNING THAT GOOGLE HAS
DEVELOPED A SECOND-GENERATION TPU, OR TENSOR PROCESSING
UNIT, THAT CAN TRAIN MACHINE LEARNING MODELS AS WELL AS
RUN THEM. OUR TPUs DELIVER A
STAGGERING 180 TERAFLOPS AND ARE BUILT FOR JUST THE KIND
OF NUMBER-CRUNCHING THAT DRIVES MACHINE LEARNING TO PUT THIS IN PERSPECTIVE OUR
NEW LARGE-SCALE TRANSLATION MODEL TAKES A FULL DAY TO TRAIN
TODAY.ON 32 OF THE WORLD'S BEST COMMERCIALLY
AVAILABLE GPUs WHILE ONLY 1/8 OF A TPU POD CAN
DO THIS JUST IN AN AFTERNOON.

BUT TPU SPECS ARE ONLY PART OF
THE STORY. THE REAL BREAKTHROUGH LIE IN HOW WE'RE
WORKING TO DEMOCRATIZE COMPUTATION AS A WHOLE. GOOGLE
CLOUD PLATFORM ALLOWS US TO MAKE
THIS INCREDIBLE NEW HARDWARE AVAILABLE TO EVERYONE.
YOU'LL SOON BE ABLE TO RENT CLOUD TPUs WITHOUT ANY UP
FRONT CAPITAL EXPENSES, THE SAME
WAY YOU CAN RENT OTHER INFRASTRUCTURES ON GOOGLE
COMPUTE ENGINE, PAYING ONLY FOR WHAT YOU NEED.
WE STRIVE TO ENSURE CONSISTENT EXPERIENCES AND PAINLESS
INTEROPERABILITY, WHETHER YOU'RE
RUNNING YOUR CODE ON CPUs, GPUs, TPUs, OR WHATEVER
COMES NEXT. IF YOU'RE INTERESTED IN BEING
ONE OF THE FIRST DEVELOPERS TO TRAIN MACHINE LEARNING MODELS
ON CLOUD TPUs, PLEASE SIGN UP AT
THIS LINK TO LEARN MORE ABOUT OUR CLOUD TPU ALPHA PROGRAMS.
I SEE ALL THE CELL PHONES.
[ LAUGHTER ] AS AN AI RESEARCHER MYSELF, I
CAN TELL YOU THAT THE RESEARCH IMPLICATIONS OF TPUs ARE
SIGNIFICANT AS WELL, WHICH IS WHY I'M SO EXCITED ALSO ABOUT
THE TENSORFLOW RESEARCH CLOUD, A
CLUSTER OF 1,000 CLOUD TPUs
THAT WE'RE MAKING AVAILABLE TO TOP MACHINE LEARNING
RESEARCHERS FOR FREE!
AS AN EXAMPLE, WE SHARE THE NEWS
ABOUT OUR CLOUD TPUs WITH HARVARD MEDICAL SCHOOL, AND
THEY'RE EAGER TO USE OUR TENSORFLOW RESEARCH CLOUD TO DO
RESEARCH AT A NATIONAL SCALE THAT JUST HASN'T BEEN POSSIBLE
TILL NOW.

WE'RE SETTING UP A PROGRAM TO
ACCEPT APPLICATIONS FOR ACCESS TO THE TENSORFLOW RESEARCH
CLOUD. AND YOU CAN SIGN UP TO LEARN MORE ABOUT THIS.
I ESPECIALLY ENCOURAGE STUDENTS AND KAGGLE USERS TO APPLY.
THESE ARE EXCITING TIMES. GOOGLE HAS SPENT YEARS
DEVELOPING SOME OF THE MOST ADVANCED AI IN THE WORLD. AND
THE EMERGENCE OF THE CLOUD MEANS
YOU CAN SHARE IT WITH EVERYONE, FROM STARTUPS TO ENTERPRISES,
FROM HEALTHCARE TO RETAIL, AND EVERYTHING IN BETWEEN.
WE CREATED THE CLOUD AI TEAM TO MAKE AI DEMOCRATIC, TO MEET YOU
WHERE YOU ARE WITH GOOGLE'S MOST
POWERFUL AI TOOLS AND TO SHARE THE JOURNEY AS YOU PUT THEM TO
USE.

WHETHER YOU'RE BUILDING
STATE-OF-THE-ART MACHINE LEARNING MODELS FROM SCRATCH OR
JUST WANT TURN-KEY SOLUTIONS FOR
IMMEDIATE RESULTS, WE'RE HERE TO
SUPPORT YOU AT EVERY STEP OF THE
WAY. NOW, TO TELL YOU MORE ABOUT HOW
GOOGLE IS IMPROVING DEVELOPMENT FOR THE WEB, PLEASE WELCOME
TAL. THANK YOU. [ CHEERS AND APPLAUSE ] Tal Oppenheimer: THANKS,
FEI-FEI. I'M A TAL FROM THE CHROME TEAM AND I'M EXCITED TO
TELL YOU ABOUT SOME OF THE GREAT
IMPROVEMENTS WE'VE MADE ON THE WEB OVER THE LAST YEAR. THE
WEB IS BIG. WITH OVER 2 BILLION
INSTANCES OF CHROME, WE KNOW THAT THE WEB HAS TREMENDOUS
REACH. BUT ONE OF THE REAL STRENGTHS OF THE WEB IS THAT
IT'S BIGGER THAN A SINGLE BROWSERS.
BROWSER. VARIOUS ESTIMATES SHOW
THAT THERE ARE WELL OVER 5 BILLION ACTIVELY USED
DEVICES, AND REGARDLESS OF WHETHER THAT
DEVICE IS A SMARTPHONE OR A LAPTOP OR A DESKTOP OR A
TABLET, THEY ALL HAVE A BROWSER.

AND
THAT MEANS THAT ANY WEB APP IS AVAILABLE ON THESE BILLIONS OF
DEVICES TODAY. AND WE'VE SEEN THIS HAVE A REAL IMPACT ON HOW
MANY USERS WEB APPS ARE REACHING.
WEAVES ALL SEEN HOW QUICKLY MOBILE HAS BEEN GROWING. AND
NATIVE APPS HAVE BEEN GROWING AT
A TREMENDOUS PACE WITH IT. BUT WHAT'S REALLY REMARKABLE IS
THAT EVEN WITH THE WEB'S LARGE
INITIAL REACH, WE'VE SEEN THE AVERAGE MONTHLY WEB AUDIENCE
GROWING EVEN FASTER.

AND BECAUSE OF THIS GROWTH, WE'RE
SEEING THE WEB EXPAND INTO NEW AREAS WITH EXPERIENCES LIKE
WEBVR BEING BUILT ON THE WEB PLATFORM. AND THE WEB
CONTINUES TO POP UP IN MORE AND MORE
PLACES. EVEN SOME WE DIDN'T REALLY EXPECT.
A COUPLE OF WEEKS AGO McDONALD McDONALD'S ANNOUNCED THAT THEY
USED THE WEB AND POLYMER TO BUILD THEIR NEW MENU BOARDS.
NOW WHEN YOU ARE LOOKING AT THE MENU AT McDONALD'S, THAT'S
BUILT ON THE WEB AS WELL. SO WITH THE WEB PRETTY MUCH
EVERYWHERE, WE ARE CONSTANTLY TRYING TO PUSH THE BOUNDARIES
OF WHAT IT CAN DO.
IF YOU LOOK AT ALL OF OUR LAUNCHES SINCE LAST YEAR'S I/O,
WE'VE SHIPPED 215 ADDITIONAL APIs THAT COVER A RANGE OF
CAPABILITIES, FROM MAKING IT EASIER TO INTEGRATE PAYMENTS
INTO YOUR EXPERIENCE, TO MAKING IT POSSIBLE TO BUILD FULLY
CAPABLE OFFLINE MEDIA EXPERIENCES DIRECTLY ON THE
WEB. AND WITH ALL OF THESE NEW
CAPABILITIES, WE'VE SEEN A MASSIVE GROWTH IN EXPERIENCES
BUILT ON THE WEB.

ACCELERATED MOBILE PAGES OR AMP PAGES MAKE
IT REALLY EASY FOR PUBLISHERS TO
CREATE FAST ARTICLES. SINCE LAUNCH WE'VE SEEN THIS GROW
FROM OVER 2 BILLION AMP PAGES FROM
ACROSS 900,000 DOMAINS. BEYOND AMP PAGES, THE MODERN MOBILE
WEB ALSO ALLOWS DEVELOPERS TO BUILD
DEEP, RICH MOBILE EXPERIENCES WITH SOMETHING WE CALLED
PROGRESSIVE WEB APPs OR PWA. PWAs. PWAs ARE ABOUT
HELPING DEVELOPERS LEVERAGE BUILD HIGH-CLASS EXPERIENCES
THAT FEEL IMMERSIVE. THEY CAN LOAD QUICKLY AND WORK OFFLINE
AND CAN EVEN SEND NOTIFICATIONS TO USERS. WE'VE SEEN A NUMBER
OF AMAZING EXPERIENCES TAKING ADVANTAGES OF THESE NEW
CAPABILITIES. AS JUST ONE EXAMPLE, THERE'S TWITTER WHO
RECENTLY REBUILT THEIR MOBILE WEB EXPERIENCE. HERE THEY HAVE
A POLISHED, FAST, IMMERSIVE EXPERIENCE THAT WORKS ON ANY
CONNECTION TYPE. AND IT CAN SEND USERS NOTIFICATIONS AND
IT'S COMPLETELY BUILT ON THE MOBILE WEB, SO IT'S ALREADY
ACCESSIBLE ON BILLIONS OF DEVICES.
AND WITH AN IMMERSIVE EXPERIENCE
LIKE THIS, WE ALSO WANT TO MAKE SURE THAT USERS CAN GET BACK TO
IT EASILY.

ADD TO HOME SCREEN HAS ALWAYS ALLOWS USERS TO ADD
ANY EXPERIENCE TO THEIR HOME SCREEN. BUT WITH OUR IMPROVED
ADD TO HOME SCREEN FLOW, WHEN YOU ADD A PWA TO YOUR HOME
SCREEN, IT'S FULLY INTEGRATED INTO THE PLATFORM. SO TO
USERS, IT FEELS LIKE ANY OTHER APP
EXPERIENCE ON THEIR DEVICE. IT WILL APPEAR IN THE ANDROID
LAUNCHER ALONGSIDE YOUR ANDROID APPS, AND IT WILL EVEN APPEAR
IN ANDROID STORAGE SETTINGS. BUT
SINCE IT'S A PWA, IT'S INHERENTLY SMALLER WITH
TWITTER'S PROGRESSIVE WEB APP AT
UNDER 1 MEGABYTE. SO USERS ARE GETTING A COMPARABLE EXPERIENCE
THAT REQUIRES SIGNIFICANTLY LESS
STORAGE SPACE. AND THE FACT THAT IT'S SO SMALL DOESN'T JUST
REDUCE ITS STORAGE SIZE BUT ALSO
MEANS THAT IT LOADS ALMOST INSTANTLY ON ANY CONNECTION
TYPE. AND THIS FAST, INTEGRATED,
IMPROVED ADD-TO-HOME SCREEN FLOW
IS ROLLING OUT NOW. WITH ALL OF THESE NEW
CAPABILITIES, WE'VE ALSO BEEN WORKING TO MAKE SURE IT'S
REALLY EASY FOR WEB DEVELOPERS TO
BUILD THESE EXPERIENCES.

WE'LL BE
GOING INTO A LOT MORE DETAIL ON HOW TO DEVELOP PWAs THROUGHOUT
THE MOBILE WEB TRACK OVER THE NEXT FEW DAYS. BUT NO MATTER
HOW YOU'RE BUILDING OUR WEB APP,
LIGHTHOUSE IS A TOOL THAT CAN SHOW YOU HOW TO IMPROVE YOUR
WEB EXPERIENCE.
LIGHTHOUSE IS A CHROME EXTENSION
AND COMMAND LINE TOOL THAT RUNS ALMOST 100 AUDIOS ON YOUR SITE
TO — AUDITS ON YOUR SITE TO IMPROVE YOUR APP'S PERFORMANCE,
ACCESSIBILITY, AND PROGRESSIVE WEB APPYNESS.
AND WE'RE EXCITED TO ANNOUNCE THAT LIGHTHOUSE WILL BE
INTEGRATED DIRECTLY DO DEVTOOLS.
SO NOW YOU CAN QUICKLY SEE HOW YOUR WEB SITE IS DOING AND WHAT
TO DO NEXT DIRECTLY IN CHROME. [ CHEERS AND APPLAUSE ]
AND WITH ALL OF THESE TOOLS, WE'VE SEEN JUST HOW EASY IT CAN
BE FOR COMPANIES TO TAKE ADVANTAGE OF THESE NEW
CAPABILITIES FOR THEIR WEB EXPERIENCE. TO GIVE ONE,
THERE'S WEGO, ONE OF THE BIGGEST
TRAVEL PLAYERS IN THE SOUTHEAST ASIA AND MIDDLE EAST THAT BUILT
ONE OF THE MOST POLISHED PWAs WE'VE SEEN.

THEIR EXPERIENCE
WORKS QUICKLY, WHETHER YOU'RE ONLINE OR OFFLINE. THEY LINK
OFF TO AMP PAGES TO ENSURE THAT PAGES LOAD QUICKLY AS WELL.
AND THEY LEVERAGE SOME OF THE NEWEST WEB APIs TO MAKE
PAYMENTS AND IDENTITY REALLY EASY FOR THEIR USERS. BUT
WHAT'S REALLY REMARKABLE IS THAT
THIS CORE PWA EXPERIENCE WAS BUILT IN JUST OVER TWO MONTHS
BY A SINGLE ENGINEER WHO WAS NEW
TO WEB DEVELOPMENT.
AND THIS IS JUST ONE EXAMPLE OF MANY. LEVERAGING THE MODERN
MOBILE WEB IS NOW THE NORM AROUND THE WORLD. WE'VE SEEN
COMPANIES EVERYWHERE BUILDING PROGRESSIVE WEB APPS AND SEEING
A TANGIBLE IMPACT ON THEIR KEY METRICS. WITH THE MODERN
MOBILE WEB, IT'S POSSIBLE TO EASILY
BUILD IMMERSIVE, FULLY CAPABLE EXPERIENCES THAT CAN REACH
BILLIONS OF PEOPLE AROUND THE WORLD TODAY.
AND NOW LET'S TURN OUR FOCUS TO WHAT WE'RE DOING TO HELP MAKE
IT EASIER TO DEVELOP APPS AND GROW
YOUR BUSINESS.

PLEASE JOIN ME IN WELCOMING BEN.
[ APPLAUSE ]
Ben Galbraith: THANKS, TAL. HEY, EVERYONE.
LAST YEAR AT I/O, WE INTRODUCED AN EXPANDED FIREBASE, A MOBILE
DEVELOPMENT PLATFORM THAT HELPS YOU WITH THINGS LIKE STORING
DATA IN THE CLOUD AND SYNCHRONIZING IT ACROSS
DEVICES, PINPOINTING APP CRASHES,
SENDING TARGETED NOTIFICATIONS TO JUST
THE RIGHT USERS, SERVING ADS IN YOUR APPS, AND MORE.
ALL OF THIS IS BUNDLED TOGETHER IN A SINGLE EASY-TO-USE
CROSS-PLATFORM SDK. FIREBASE ALSO INCLUDES A POWERFUL FREE
AND UNLIMITED ANALYTICS TOOL PURPOSE-BUILT FOR THE NEEDS OF
NATIVE APPS AND NEW THIS YEAR, ANALYTICS GIVES YOU REALTIME
VIEWS INTO WHAT'S HAPPENING INSIDE OF YOUR APP WHICH OPENS
UP SORT OF A LIVE WINDOW INTO WHAT'S HAPPENING RIGHT NOW.
FIREBASE IS ALSO INTEGRATED WITH
THE GOOGLE CLOUD PLATFORM WHICH MEANS IT SCALES WITH YOU AS
YOUR NEEDS GROW. FOR EXAMPLE,
ANALYTICS CONNECTS SEAMLESSLY WITH BIGQUERY WHICH MEANS YOU
CAN EXECUTE FAST SQL-LIKE QUERY
AT DATA AT SCALE. SINCE LAST YEAR'S LAUNCH OVER A MILLION
DEVELOPERS ARE USING FIREBASE.

WE ARE SO HUMBLED THAT SO MANY
OF YOU HAVE TAKEN THIS JOURNEY WITH US AND HAVE CHOSEN TO USE
US IN YOUR APP. WE'RE DEEPLY COMMITTED TO
FIREBASE, AND WE'RE DOUBLING DOWN ON OUR EFFORTS TO SIMPLIFY
MORE EVERYDAY DEVELOPER CHALLENGES. TO THAT END, IN
JANUARY, THE FABRIC TEAM JOINED GOOGLE. SINCE FIRST LAUNCHING
CRASH LYTICS IN 2011, THE FABRIC
TEAM HAS BEEN A SIMILAR MISSION TO OUS AND HAVE BUILT
REMARKABLE SET OF PRODUCTS THAT HAVE
ACHIEVED WIDESPREAD DEVELOPER ADOPTION. THE FIREBASE AND
AFRICA TEAMS ARE HARD AT WORK INTEGRATING THESE TWO PLATFORMS
TOGETHER IN A THOUGHTFUL WAY TO BRING YOU THE BEST OF BOTH.
WE'LL HAVE MORE TO SHARE ON THIS
FRONT IN THE COMING MONTHS. OVER THE PAST YEAR, WE'VE BEEN
CONTINUOUSLY IMPROVING AND EXPANDING FIREBASE. AND TODAY
I WANT TO HIGHLIGHT A COUPLE OF
OF THE ENHANCEMENTS THAT WE'VE
MADE STARTING WITH CLOUD FUNCTIONS.
ONE OF OUR GOALS WITH FIREBASE IS FREEING YOU FROM HAVING TO
THINK ABOUT SERVERS AND INFRASTRUCTURE SO YOU CAN FOCUS
ON CREATING GREAT APPS.

BUT SOMETHING'S BEEN MISSING FOR US
TO TRULY ACCOMPLISH THIS GOAL, AND IT'S A GAP THAT WE'RE NOW
ABLE TO FILL WITH CLOUD FUNCTIONS FOR FIREBASE, WHICH
WE JUST RECENTLY RELEASED INTO
BETA. CLOUD FUNCTIONS GIVES YOU AN
EASY WAY TO DEPLOY JAKE WHARTON CODE INTO THE CLOUD AND THIS —
GENTLEMAN HAVE ASCRIPT CODE INTO
THE CLOUD AND IT CAN INTEGRATE INTO FIREBASE EVENS. THESE
FUNCTIONS RUN IN AN MAD NODE.JS ENVIRONMENT SO YOU CAN EASILY
TAP INTO THE VAST NODE APACHEJ ECOSYSTEM.

YOU CAN USE THESE
FUNCTIONS TO DO THINGS LIKE RESPOND TO A DATABASE UPDATE BY
SENDING NOTIFICATION WITH CLOUD MESSAGING OR YOU CAN RESIZE
IMAGES UPLOADED BY YOUR USERS BEFORE SAVING THEM WITH CLOUD
STORAGE. AND TODAY, WE'RE OPENING UP A
NEW INTEGRATION BETWEEN FUNCTIONS AND FIREBASE HOSTING. NOW, HOSTING LET'S YOU SERVE
STATIC CONTENT LIKE HTML AND CSS
FILES THAT ARE AUTOMATICALLY BACKED BY A GLOBAL CACHING
NETWORK, BY COMBINING THOSE WITH
CLOUD FUNCTIONSES, YOU CAN NOW GENERATE DYNAMIC WEB CONTENT
THAT YOU CAN SERVE ON OUR OWN DOMAIN WITH A STATIC CONTENT
AND IS BOTH ACCELERATED BY THIS
GLOBAL CACHING NETWORK. SO AS WITH CLOUD FUNCTIONS, YOU
CAN DEPLOY INDIVIDUAL UNITS OF CODE AS YOU NEED THEM, WHICH
GIVES YOU A REALLY ELEGANT WAY TO FACTOR CODE OUT FROM YOUR
APPS AND SHARE THEM ACROSS YOUR WEB AND NATIVE APPS AS YOU NEED
WITHOUT HAVING TO WORRY ABOUT APP SERVERS OR SERVER-SIDE
APPLICATIONS. AND IT ENABLES TRUE SERVERLESS DEVELOPMENT.
WE ARE REALLY EXCITED ABOUT THIS.
ALL RIGHT. I HAVE GOT ONE MORE THING I WANT TO SHARE WITH YOU. AND THIS HAS TO DO WITH YOUR
NATIVE APPS QUALITY.

AS DEVELOPERS, WE SPEND A LOT OF
TIME OPTIMIZES AND TESTING OUR APPS TO GET THEM TO FORM
PERFORM JUST RIGHT. WHEN WE RELEASE
THEM INTO THE WILD IT'S REALLY OWN OUR USERS THAT HOE HOW THEY
ARE PERFORMING. IT'S HARD TO KNOW EXACTLY HOW THEY ARE
BEHAVING ACROSS A HUGE ARRAY OF DEVICES AND VARIED NETWORK
CONDITIONS ACROSS THE WORLD. AND NOT HAVING THEY
WILL.PERFORM WELL IS FRUSTRATING FOR
EVERYONE. WE ARE RELEASING A NEW PRODUCT TO HELP CALLED
FIREBASE PERFORMANCE MONITORING.
AFTER YOU ADD FIREBASE PERFORMANCE — THANK YOU.
AFTER YOU ADD FIREBASE PERFORMANCE WITH YOUR APP WITH
ONE LINE OF CODE, FIREBASE PERFORMANCE AUTOMATICALLY
PROVIDES INSIGHTS INTO TWO OF THE MOST CRITICAL ASPECTS OF
APP PERFORMANCE, STARTUP TIME AND
NETWORK RESPONSIVENESS. YOU CAN THEN USE IT'S SIMPLE
API — [ APPLAUSE ]
THANK YOU. YOU CAN USE ITS SIMPLE API TO MEASURE VIRTUALLY
ANYTHING IN YOUR APP AS YOU SEE ON THE SLIDE, YOU JUST INVOKE A
FUNCTION AT THE BEGINNING AND THEN AT THE END AND FIREBASE
PERFORMANCE DOES THE HEAVY LIFTING OF COLLECTING ALL OF
THE PERFORMANCE METRICS FOR YOU
ACROSS ALL OF YOUR APP INSTANCES.
AND THEN YOU CAN FILTER THESE METRICS BY COUNTRY, DEVICE
TYPE, OS, AND APP VERSION TO GET A
CLEAR VIEW OF WHERE YOU NEED TO FOCUS YOUR EFFORTS.
THE BETA VERSION OF FIREBASE PERFORMANCE IS AVAILABLE TODAY.
[ APPLAUSE ] THANK YOU.
WE HOPE THIS MAKES A BIG DIFFERENCE IN YOUR EFFORTS TO
CREATE HIGH-PERFORMING NATIVE APPS.
WE HAVE A BUNCH OF OTHER FIREBASE ANNOUNCEMENTS TODAY AT
SESSIONS HERE AT I/O, INCLUDING SUPPORT FOR PHONE NUMBER
AUTHENTICATION AND WE'RE OPEN SOURCING MANY OF OUR FIREBASE SDKs.
[ CHEERS AND APPLAUSE ] THANKS TO NEW ENHANCEMENTS WE'VE
ALSO MADE THE TEST LAB FOR ANDROID AND OUR RECENTLY
RELEASED UNITY AND CPU CPU C++ DEVELOPERS, TOO.

WE WANT
FIREBASE TO BE THE BEST PLACE FOR YOU TO START YOUR NEXT APP,
FREEING YOUR ENERGIES TO FOCUS ON MAKING YOUR APP AWESOME
WHICH IS WHERE YOU SHOULD BE SPENDING
ALL YOUR TIME. THANK YOU. AND NOW I WOULD
LIKE TO BRING JASON BACK UP.
[ APPLAUSE ] Jason Titus: THANKS, BEN.
AS YOU CAN SEE, AT GOOGLE, WE'VE
BEEN WORKING ACROSS A RANGE OF TEAMS TO MAKE IT EASIER TO
BUILD PRODUCTS. DURING I/O, YOU'LL
HAVE AN OPPORTUNITY TO GO DEEP INTO A NUMBER OF THESE, WITH 14
CONTENT TRACKS AND OVER 140 BREAKOUT SESSIONS, COVERING
EVERYTHING FROM ANDROID TO THE CLOUD TO VR.
WE ALSO HAVE SANDBOXES TO HELP YOU GET HANDS-ON EXPERIENCE
WITH OUR PRODUCTS AS WELL AS OVER 70
CODE LABS TO GET YOU UP AND RUNNING WITH OUR LATEST APIs
TODAY.

IN ADDITION, THE GOOGLERS THAT
BUILT THESE PRODUCTS ARE HERE SO
GRAB THEM FOR ONE-ON-ONE CONSULTATIONS IN OFFICE HOURS
OR AT THE SANDBOXES. NOT ONLY CAN
THEY HELP YOU UNDERSTAND OUR PRODUCTS BUT MORE IMPORTANTLY
THEY CAN GET YOUR FEEDBACK ON HOW WE'RE DOING.
I DO HAVE ONE OTHER ANNOUNCEMENT
BEFORE WE GO OUT TO BREAKOUT SESSIONS. AS YOU CAN TELL,
WE'RE REALLY EXCITED ABOUT THE FUTURE OF AI AND PARTICULARLY
OUR GOOGLE ASSISTANT PLATFORM. AND SO TO GET YOU RAMPED UP,
WE'RE HOSTING OUR FIRST-EVER ACTIONS ON GOOGLE DEVELOPER
CHALLENGE BY BUILDING CREATIVE, USEFUL OR SIMPLY FUN APPS FOR
THE GOOGLE ASSISTANT, YOU CAN COMPETE TO WIN ONE OF OVER 20
PRIZES.

AND FOR THOSE OF YOU HERE AT
SHORELINE, WE'RE GIVING YOU A GOOGLE HOME DEVICE AND $700 OF
CLOUD CREDIT TO GET YOU STARTED.
[ CHEERS AND APPLAUSE ] WE CANNOT WAIT TO SEE WHAT YOU
BUILD! SO SUNDAR TALKED ABOUT THE
TECHNOLOGICAL SHIFT TO AI. AS WELL AS THE POWER OF OPEN
PLATFORMS. THIS IS A REALLY EXCITING TIME IN COMPUTING. WE
HOPE YOU'RE AS INSPIRED AS WE ARE ABOUT THE FUTURE. AND,
REMEMBER, ALL OF US HERE AT GOOGLE ARE HERE TO HELP YOU
THIS WEEK. SO PLEASE TAKE ADVANTAGE
OF IT. AND LET'S BUILD GREAT THINGS
TOGETHER. THANK YOU AND HAVE FUN! PLUS PLUS [ APPLAUSE ] [ CHEERS AND APPLAUSE ] Chet Haase: HELLO, AND WELCOME
TO WHAT'S NEW IN ANDROID, OR, AS
I, THE ONLY PERSON, LIKE TO REFER TO IT AS THE ANDROID
KEYNOTES. I'M CHET HAASE FROM THE ANDROID UI TOOLKIT TEAM.
Romain Guy: ROMAIN GUY FOR THE GRAPHICS TEAM.
Dan Sandler: AND I'M DAN SANDLER, FROM THE SYSTEM UI
TEAM. AND WE DON'T HAVE A LOT OF
TIME, SO LET'S GET TO IT.
ARE YOU READY FOR WHAT'S NEW IN ANDROID?
HERE'S WHERE WE LEFT OFF LAST TIME.

API 25. SO WE'RE JUST
GOING TO GRAP THAT THERE, POP IT
INTO GIT DIFFICULT AND OFF WE GO.
YOU'RE GOING TO WANT TO WRITE THIS DOWN.
[ LAUGHTER ] OKAY. NEXT.
YEAH, THAT WAS A GOOD ONE. OKAY.
Chet Haase: I LOVE THOSE. Dan Sandler: REMEMBER, WE
ALMOST NAD THAT AN ENUM? IT WAS
HILARIOUS. YOU GOT THAT? YOU THINK THIS
IS WHAT PEOPLE CAME FOR? I DON'T KNOW WHY WE DIDN'T THINK
OF THIS BEFORE. SO WE'VE BEEN DOING THIS TALK,
TELLING YOU WHAT'S NEW FOR YEARS, AND YOU CAN SEE THAT —
I FORGOT MY BALLET BLAZER.

I HAD
A LOVELY RED BLAZER, BUT SOMEBODY BORROWED IT FOR THE
KEYNOTE. BUT THIS YEAR WAS A LITTLE
DIFFERENT. HAD YOU THE DEVELOPER PREVIEWS WELL IN
ADVANCE, SO YOU'VE SEEN A LOT OF
THESE APIs BEFORE. YOU HAD THE GOOGLE KEYNOTE WHERE WE
SHOWED OFF A LOT OF REALLY EXCITING STUFF. WE HAD A
DEVELOPER KEYNOTE, WHERE YOU LEARNED ABOUT EVEN MORE
DEVELOPER STUFF. SO WHAT ARE WE DOING HERE?
WHAT IS THE POINT OF WHAT'S NEW IN
ANDROID? Chet Haase: EXISTENTIAL CRISIS.
Dan Sandler: SO — DID YOU TEST
THIS CLICKER? Chet Haase: I DID, I DID.
Dan Sandler: THINK OF THIS TALK
LIKE A WINE TASTING OR A WHISKEY
FLIGHT OR ONE OF THOSE SODA MACHINES THAT YOU CAN PUSH ALL
THE BUTTONS ON. THIS IS AN ARTISINAL,
HAND-PICKED SELECTION OF THINGS YOU MAY HAVE OVERLOOKED IN THE
NEW RELEASE OF ANDROID.

THINGS YOU'RE GOING TO NEED TO DO NO
MATTER WHAT TO BE PART OF ANDROID O. AND, WELL,
HONESTLY, JUST THINGS WE'D LIKE TO TALK
ABOUT, AND WE'RE ONSTAGE. SO WITH THAT, THIS IS REALLY
WHAT'S NEW IN ANDROID, SPECIFICALLY, WHAT YOU MIGHT
HAVE MISSED IN THE DEVELOPER PREVIEW OR THE I/O KEYNOTE OR
THE OTHER KEYNOTE, AND WHY YOU SHOULD CARE.
ONE LAST THING THAT I WANT TO MAKE SURE WE GET TO TODAY IS
THIS. EVERYBODY'S ALWAYS EXCITED ABOUT THIS.
WE'RE GOING TO HOLD THAT FOR THE
END. (GROANING).
Speaker: IT'S GOING TO BE GOOD. Dan Sandler: LET'S GET
STARTED, ROMAIN, AND TALK ABOUT UI AND
GRAPHICS. Romain Guy: YES, LET'S START.
THE FIRST FEATURE WE WANT TO TALK ABOUT IS ONE THAT YOU SAW
THIS MORNING IN ONE OF THE KEYNOTES. CHET, THIS CLICKER
DOES NOT WORK. YOU DIDN'T TEST IT.
[ LAUGHTER ] Chet Haase: YOU KNOW, YOU
KNOW — WASTING TIME.

I'M GOING TO STAND BACK HERE
AND DO THE SLIDES FOR YOU.
Romain Guy: ALL RIGHT. GO TO THE NEXT SLIDE.
Dan Sandler: THIS IS WHY THEY DIDN'T WANT TO GIVE US A
CLICKER. [ LAUGHTER ]
Romain Guy: SO IF YOU — [ LAUGHTER ]
Dan Sandler: Chet Haase: IT WORKS FOR ME.
Romain Guy: JUST GO BACK THERE.
I DON'T WANT TO SEE YOU. SO THE FIRST FEATURE THAT YOU
SAW THIS MORNING IN ONE OF THE KEYNOTES, PICTURE IN PICTURE,
IS NOT JUST FOR TV ANYMORE. IT'S
ALSO FOR YOUR PHONE. HERE WE HAVE AN EXAMPLE WITH
THIRD-PARTY APPLICATION, NETFLIX, RUN
ONGOING YOUR PHONE, PICTURE IN PICTURE.
GIVE ME THAT CLICKER. Chet Haase: LET'S MOVE BACK.
THERE WE GO. Romain Guy: IT'S REALLY EASY
TO IMPLEMENT IN YOUR APPLICATION.
YOU JUST HAVE TO MODIFY YOUR MANIFEST. AND STOP PLAYING THE
ANIMATION, PLEASE. YOU JUST HAVE TO SAY SUPPORT
PICTURE IN PICTURE TRUE, YOU DON'T NEED TO RESIZE THE
ACTIVITY PICTURE TRUE ANYMORE, AND YOU SHOULD ALSO TEST
CONFIGURATION CHANGES. AND IN YOUR CODE, WHEN YOU WANT
TO ENTER THE PICTURE IN PICTURE CODE, YOU HAVE ONE CALL, YOU
CALL ENTER PICTURE IN PICTURE.

SUPER SIMPLE AND IT'S GOING TO
MAKE YOUR USERS SUPER HAPPY. A FEATURE DEAR TO MY HEART,
MANAGEMENT, ADDING SUPPORT — IT
WILL ONLY BE ON DEVICES THAT — WE'LL ENABLE IT FOR YOUR
APPLICATION. ADDING SUPPORT FOR
16-BIT PNG FILES, WIDER COLORS,
MORE SATURATED. WE SUPPORT ICC PROFILES, COLORS IN —
IF WILL ENSURE ACCURATE RENDITION OF COLORS ACROSS
MULTIPLE SCREENS. WE ALSO HAVE A BUNCH OF NEW
APIs WHICH WE'RE GOING TO TALK ABOUT MORE AT THE END OF THE
WEEK IN A DIFFERENT TALK.

SO BECAUSE A PICTURE IS WORTH A
THOUSAND WORDS, THIS IS COLOR MANAGEMENT AND HOW IT WORKS.
HOPE IT'S CLEAR. .
[ LAUGHTER ] BUT, REALLY, THE COLOR
MANAGEMENT IS ABOUT SOMETHING YOU'VE PROBABLY EXPERIENCED
WITH YOUR OWN APPLICATION, YOUR
COLORS LOOK DIFFERENT ACROSS DEVICES, SO WE HAVE SOLUTIONS
FOR YOU IN ANDROID O. SO IF YOU
WANT TO KNOW MORE, THERE'S GOING
TO BE A TALK THAT I'M GOING TO GIVE ON FRIDAY AT 11:30 ONSTAGE
2. IT'S CALLED UNDERSTANDING COLOR.
NEXT, WE'RE ALSO ADDING SUPPORT FOR MULTIPLE DISPLAYS. IF RUR
APPLICATION IF YOUR APPLICATION
IS ALREADY — CLICKER IS HORRIBLE — IF YOUR APPLICATION
SUPPORTS MULTIPLE WINDOWS ALREADY, THE MULTIWINDOW MODE,
IT ALREADY SUPPORTS MULTIPLE DISPLAY IN O.
WHEN THE PHONE IS CONNECTED OR AN ANDROID DEVICE IS CONNECTED
TO MULTIPLE DISPLAYS AND YOU HAVE AN APPLICATION THAT IS
COMPATIBLE, THE USER CAN SEND THE APPLICATION ON A DIFFERENT
DISPLAY.

WHEN THIS HAPPENS, YOU'RE GOING TO GET RESIZING
CONFIGURATION CHANGE. YOU CAN ALSO CONTROL ON WHAT DISPLAY
YOUR ACTIVITY SHOWS UP. YOU CAN
USE THE ACTIVITY OPTIONS FOR THAT.
AND YOU SHOULD REALLY TEST YOUR APP IF YOU WANT TO SUPPORT THIS
FEATURE. TO HELP YOU WITH TESTING, WE
HAVE TWO NEW DEVELOPER TOOLS, YOU CAN RUST ABD SHELL DUMPSYS. IF YOU CALL ABD SHELL START
WITH YOUR ACTIVITY INTENT. YOU
CAN — IT'S A VERY EASY WAY FOR YOU TO TEST THIS.
THERE'S A LOT MORE TO THOSE APIs, SO WE ENCOURAGE YOU TO
GO TO THE OFFICE HOURS ON FRIDAY AND THURSDAY, THE OFFICE
HOURS FOR WINDOWS AND ACTIVITIES.
NEXT, MEDIA. [ LAUGHTER ]
SO WE HAVE A LOT OF VERY USEFUL CLASSES IN THE MEDIA PACKAGE,
THE RECORDER, THE EXTRACTOR AND THE CODEC, WE ADDED A NEW GET
METRICS API, IT HELPS TO QUERY ABOUT THE MEDIA YOU'RE DEALING
WITH, THE BIT RATE, THE CODEC, THE DURATION, THIS KIND OF DATA
.

IT'S SUPER EASY TO USE, JUST THOSE
OBJECTS AND YOU GET THE PERSISTIBLE BUNDLE AND YOU CAN
LOOK UP THE DOCUMENT ON DWEP.ANDROID.COM TO KNOW WHAT
KIND OF QUERIES ARE AVAILABLE. PLAYBACK IS ALSO MUCH IMPROVED. YOU NOW HAVE CONTROL OVER THE
BUFFERING NEW APPLICATION. SO YOU CAN SPECIFY A LOW AND A
HIGH WATERMARK.
SO THE PLAYBACK OF THE VIDEO WILL NOT START UNTIL YOU REACH
THE LOW WATERMARK, AND THE SYSTEM WILL DO ITS BEST TO KEEP
CACHED DATA BETWEEN THE SLOW AND
THE HIGH WATERMARK. AND YOU CAN
SPECIFY THE WATERMARKS IN DURATION OR AMOUNT OF DATA IN
SIZE. WE ALSO IMPROVED SEEKING. SO
WHEN YOU SEEK INTO A VIDEO, YOU CAN NOW CHOOSE THE BEHAVIOR, DO
YOU WANT TO SEEK TO THE CLOSEST FRAME, THE NEXT KEY FRAME, TO
THE PREVIOUS KEY FRAME, OR TO THE CLOSEST SYNC FRAME.
FINALLY, WE MADE THE DRM PLAY PLAY BACK IN WIDEVINE A LOT
EASIER IN ALL OF YOUR APPLICATIONS.
FOR RECORDING, UNTIL NOW, THE MEDIA MIXER ONLY LETS YOU
HAVE — SORRY, ADD ONE VIDEO TRACK AND/OR ONE AUDIO TRACK.

NOW YOU CAN HAVE AS MANY AUDIO ENGINEER TRACKS AS YOU WANT.
YOU CAN ALSO CREATE CUSTOM TRACKS. THE (INDISCERNIBLE)
HAS TO START WITH APPLICATION
SLASH, AND IT'S BASICALLY A SIDE BAND
WHERE YOU CAN INVOKE ANY KIND OF
DATA YOU WANT. TO — TO REPLACE
UP TO 16 VIDEO OR SOMETHING LIKE
THAT. WEBVIEW COMES WITH REALLY
USEFUL NEW APIs. WE'VE ADDED THE ABILITY TO DO SAFE BROWSING
THAT YOU KNOW AND LOVE FROM CHROME THAT DETECTS MALWARES
AND UNSECURE WEB PAGES. SO IF YOU
ADD THIS TAG IN YOUR MANIFEST, THIS METADATA TAG, IT'S GOING
TO USE THE SAME BACK END AND API
THAT CHROME ITSELF USES TO SECURE THE BROWSING EXPERIENCE
FOR YOUR USERS.

THE WEBVIEW USES NOW MULTIPLE
PROCESSES. AND, IN PARTICULAR, THERE'S A RENDER PROCESS. WE
HAVE A NEW API TO DEAL WITH THESE MULTIPLE PROCESSES. IF
THE RENDERS PROCESS CRASHES, YOU
CAN USE THE TERMINATION HANDLE API TO DETECT THE CRASH AND
DECIDE WHAT TO DO IN YOUR APPLICATION. YOU CAN CRASH
YOUR APPLICATION IF YOU WANTED. YOU
CAN TRY TO RESTART THE WEBVIEW, OR YOU CAN JUST LOG SOMETHING
AND SHOW A MESSAGE TO THE USER. BEFORE.
YOU CAN USE THE RENDER (INDISCERNIBLE) API TO BETTER
DEAL WITH THE LOW MEMORY SITUATIONS. SO WHEN THE SYSTEM
IS LOW ON MEMORY, IT'S GOING TO TRY TO RECLAIM RAM FROM
SOMEWHERE, AND YOU CAN TELL THE SYSTEM WHETHER YOUR WEBVIEW IS
VERY IMPORTANT OR NOT THAT IMPORTANT TO YOUR APPLICATION.
SO IF THE WEBVIEW IS CRITICAL TO
YOUR APPLICATION, YOU SHOULD DEFINITELY TAKE A LOOK AT THIS
API.

Chet Haase: SO YOU KNOW IT'S
THE RIGHT BUTTON; RIGHT? Romain Guy: YES, I KNOW THAT.
[ LAUGHTER ] Chet Haase: SO THERE WERE A
COUPLE OF LONG-REQUESTED FEATURES FOR ANIMATORS,
SPECIFICALLY FOR ANIMATOR SETS. CEPTIVELY TRICKY TO IMPLEMENT,
SO IT TOOK A WHILE. IN ANDROID O, WE HAVE THE CAPABILITY IN
ANIMATOR SETS OF HAVING SEEKING.
IF YOU HAVE AN ANIMATOR THAT'S A
COLLECTION OF CHILD ANIMATORS, YOU CAN SEEK WITHIN THOSE CHILD
ANIMATORS IN THE OVERALL ANIMATORSET.

SO YAY.
WE ALSO HAVE THE ABILITY — [ LAUGHTER ]
— TO REVERSE. Romain Guy: DIDN'T YOU TRY TO
IMPLEMENT THOSE APIs A WHILE AGO?
Chet Haase: MAYBE. Romain Guy: UH-HUH. AND WHO
IMPLEMENTED THE APIs IN THE END?
Chet Haase: NOT ME. Romain Guy: EXACTLY.
[ LAUGHTER ] Chet Haase: OKAY. SO NEW
CAPABILITY, AGAIN, IN ANIMATORSET TO REVERSE. SO YOU
NO LONGER HAVE TO ,YOU KNOW, SET
UP A SEPARATE ANIMATORSET WITH ALL THAT FUNCTIONALITY AND GET
A LISTEN AND ALL THAT. WE DO ALL
OF THAT TEDIOUS WORK FOR YOU. SO YAY.
AUTOFILL, BECAUSE IT'S REALLY TEDIOUS TO GET ALL THIS
INFORMATION CORRECT OVER AND OVER, WE SAW THIS IN THE
KEYNOTE EARLIER. IT'S THE ABILITY TO
— YOU'VE GOT A FORM TO FILL IN.
THERE'S A PROVIDER THAT CAN GIVE
YOU THAT INFORMATION. SO WHEN YOU GET THOSE TEXT FIELDS, WE
CAN AUTOMATICALLY ENTER THAT INFORMATION FOR YOU. AND THERE
ARE A COUPLE OF DIFFERENT ASPECTS TO THIS. ONE IS THAT
YOU CAN CERTAINLY IMPLEMENT YOUR
OWN SERVICE AND PROVIDE THAT CAPABILITY OR DEPEND ON SERVICE
THAT QUEER PROVIDING — THE STANDARD VIEWS JUST WORK, IF
YOU'RE USING TEXTVIEW, IF YOU'RE
USING EDIT TEXT, WE KNOW HOW TO RECEIVE THIS INFORMATION,
INTERACT WITH THE SERVICE ALREADY.

SO YOU DON'T NEED TO
DO ANYTHING FOR STANDARD VIEWS. IF YOU'RE USING CUSTOM VIEWS OR
IF YOU WANT TO PROVIDE MORE INFORMATION ABOUT STANDARD
VIEWS, WE HAVE APIs FOR PROVIDING HINTS TO US ABOUT
WHAT THE VALUE TYPES ARE, AS WELL AS
APIs TO TELL US MORE ABOUT YOUR CUSTOM VIEWS AND HOW YOU
WANT TO INTERACT WITH THAT.

ALSO, IF YOU HAVE A CUSTOM VIEW
HIERARCHY, LET'S SAY YOU HAVE A SURFACEVIEW, WHERE YOU HAVE
VIEWS INSIDE OF THERE, BUT ALL WE KNOW IS THAT THERE'S A
SURFACEVIEW, THEN THERE ARE APIs FOR YOU TO TELL US ABOUT
THE VIRTUAL HIERARCHY THAT YOU WANT US TO INTERACT WITH.
THERE IS GOING TO BE MORE ABOUT THIS IN A SESSION ON FRIDAY
MORNING. SO GO TO THAT IF YOU WANT TO LEARN MORE ABOUT
AUTOFILL. AND NOW LET'S TALK A LITTLE BIT
ABOUT TEXT. THERE'S BEEN A BUNCH OF STUFF GOING ON IN THE
TEXT ARENA THIS TIME.

I THINK WE CAN REWRITE THIS. THERE WE
GO. [ LAUGHTER ] I ONLY USE THAT FONT BECAUSE IT
HURTS DAN. IT JUST PHYSICALLY HURTS HIM. IT'S AWESOME.
Romain Guy: I THINK YOU BROKE HIM.
Chet Haase: ALL RIGHT. SO, FIRST OF ALL, YOU CAN USE XML TO
DECLARE FONT INFORMATION USING SORT OF A NEAT HACK WITH DATA
BINDING. BUT IT'S KIND OF TRICKY TO DO. AND WHY
SHOULDN'T WE ACTUALLY PROVIDE THAT
CAPABILITY FOR YOU? SO NOW WE DO. SO YOU CAN NOW
ACTUALLY PUT A FONT FILE DIRECTLY IN THIS NEW RESOURCE
FONT DIRECTORY.

[ CHEERS AND APPLAUSE ] YAY, INDEED.
SO, PUT THAT IN THE DIRECTORY, OR YOU CAN TELL US ABOUT THE
FONT FAMILY SO YOU CAN PROVIDE SEVERAL FONTS WITH INFORMATION
ABOUT THE STYLES OF EACH. AND THEN YOU CAN JUST USE THOSE
DIRECTLY AS YOU COULD ANY OTHER AND FROM CODE, YOU JUST SAY,
GIVE ME THAT RESOURCE, AND AWAY YOU GO.
DOWNLOADABLE FONTS. NOW WE HAVE
THE CAPABILITY FOR YOU TO DECLARE A FONT THAT YOU WANT TO
USE THAT WE WILL THEN DOWNLOAD AND CACHE ON THE SYSTEM FOR YOU
IF IT IS NOT THERE YET OR IF IT IS ON THE SYSTEM, THEN WE'LL
USE IT FROM THE CACHE. YOU CAN DO THIS FROM CODE OR
FROM XML AND USE IT AS A RESOURCE, JUST LIKE YOU DID IN
XML FONTS ON THE PREVIOUS EXCITING SLIDE.
AND WE ALSO HAVE A FONT PROVIDER
THAT WE ARE PROVIDING IN A NOT YET RELEASED VERSION OF GOOGLE
PLAY SERVICES.

THERE IS A BETA VERSION OF THAT AVAILABLE AT
THE CONFERENCE THIS WEEK. I DON'T
KNOW THE DETAILS ON THAT. BUT THERE'S A SESSION WHERE YOU CAN
LEARN THE DETAILS, OR YOU SHOULD
BE ABLE TO GO TO THE PLAY SERVICES WEB SITE TO LEARN MORE
ABOUT THAT. AND THIS GIVES YOU ACCESS TO
ALL THE OF GOOGLE FONTS. SO IF YOU
JUST WANT TO USE ONE OF THE STANDARD ONES, SUCH AS THAT
BEAUTIFUL FONT I USED TO KICK OFF THIS SECTION, MAYBE THAT'S
IN THERE, THEN YOU CAN ASK FOR
THAT DIRECTLY FROM THE SERVICE. ALSO, THERE'S THE ABILITY TO
HAVE AUTO-SIZING TEXTVIEW. SO TYPICALLY, IF YOU RESIZE A
TEXTVIEW — [ CHEERS AND APPLAUSE ]
Dan Sandler: YOU NEVER KNOW WHAT'S GOING TO BE THE HIT;
RIGHT? Chet Haase: TEXT, TEXT IS
COOL. Dan Sandler: TEXT.
Chet Haase: ESPECIALLY WHEN IT'S IN THE RIGHT FONT.
SO WHAT YOU GET NOW IS THE BEHAVIOR ON THE LEFT THERE,
WHERE WE'RE JUST RESIZING THE VIEW ITSELF, THERE'S NO CHANGE
TO THE FONT.

BUT ON THE RIGHT, IF YOU OPT INTO THE
AUTO-SIZING TEXTVIEW BEHAVIOR, THEN WE'RE GOING TO RESIZE THE
FONT FOR YOU. AND YOU CAN SPECIFY THE BEHAVIOR, THE STEP
INCREMENTS THAT YOU WANT TO USE,
OR THE SPECIFIC SIZE THAT YOU WANT TO SNAP TO AS IT RESIZES.
SO THERE'S APIs FOR THAT. THERE'S APIs IN BOTH XML, AS
WELL AS JAVA PROGRAMMING LANGUAGE CODES. SO KNOCK
YOURSELF OUT. AND FOR ALL OF THESE TEXT
FEATURES, XML FONTS, DOWNLOADABLE FONTS, AND
AUTO-SIZING TEXTVIEW, THEY'RE TALKING ABOUT ALL OF THESE IN
THE WHAT'S NEW SUPPORTED LIBRARY
SESSION. AREN'T THEE O PLATFORM
APIs? YES, THEY ARE, AND THEY ARE ALSO IN SUPPORT LIBRARIES.
[ CHEERS AND APPLAUSE ] SO YOU CAN USE ALL OF THESE
CAPABILITIES GOING BACK ON EARLIER RELEASES.
ACCESSIBILITY SERVICE UTILITIES.
IF YOU'RE WRITING AN ACCESSIBILITY SERVICE, GREAT
THING TO DO, WE HAVE NOW CAPABILITIES THAT YOU CAN TAKE
ADVANTAGE OF, LANGUAGE DETECTION, THE ABILITY TO PUT A
BUTTON IN THE NAVIGATION BAR, ALONG WITH THE OTHER BUTTONS
THERE, TO MAKE IT EASIER TO ACCESS YOUR STUFF, SEPARATE
VOLUME CONTROL FOR ACCESSIBILITY
VOLUME SO YOU'RE NOT CONFLATING THAT VOLUME WITH THE VOLUMES ON THE DEVICES.

AND ALSO THE
ABILITY TO DEFINE CUSTOM GESTURES, FINGERPRINT GESTURES. IF YOU WANT TO LEARN ANYTHING
MORE ABOUT THESE, THERE'S A SESSION THIS AFTERNOON ON
ACCESSIBILITY THAT YOU SHOULD CHECK OUT.
FINALLY, ONE OF MY FAVORITE REALLY TINY CHANGES, I'M GOING
TO SAY TINY BECAUSE IT'S ONE LINE OF CODE FOR THE API. BUT
THE ACTUAL CLs THAT WENT IN TO FIX ALL THE CODE THAT WAS
DEPENDENT UPON THE FORMER IMPLEMENTATION WAS HUGE. SO I
DON'T WANT TO DETRACT FROM THE WORK FROM IT. BUT API-WISE,
KIND OF TINY, HIDDEN, KIND OF LOOKS LIKE THE SAME THING FROM
THE OUTSIDE. THE WAY FINDVIEWBYID, AND THEN
YOU CALL THAT, YOU PASS IN YOUR RESOURCE ID AND GET BACK A
VIEW, AND THEN YOU IMMEDIATELY CAST
IT INTO WHAT YOU WANT.

SO
TEXTVIEW, YOU HAVE TO TELL IT TO
TEXTVIEW ON BOTH THE LEFT AND THE RIGHT AND THERE'S
PARENTHESES AND IT'S A BIG BOTHER. PEOPLE USE HELPER
LIBRARIES JUST TO GET AROUND THE
FACT THAT THIS LOOKS SO HORRIBLE.
SO NOW — [ CHEERS AND APPLAUSE ]
— WE HAVE THIS. I CALL THIS FEATURE CASTAWAY.
I THINK I AM THE ONLY ONE THAT
DOES SO. [ LAUGHTER ]
Dan Sandler: ALL RIGHT. MY FIRST SLIDE. I'M GOING TO
TALKS A LITTLE BIT ABOUT SOME OF THE
UI SYSTEM STUFF YOU'RE GOING TO LOOK AT.
IF YOU HAVE AN APP, YOU'RE GOING
TO NEED TO KNOW ABOUT ADAPTIVE ICONS. I THINK THIS GOT BARELY
A MENTION IN ONE OF STEPH'S SLIDES EARLIER TODAY. BUT,
ESSENTIALLY, THIS IS — WE'RE TRYING TO SAVE YOU TIME AND
MONEY.

THERE ARE SO MANY LAUNCHERS OUT THERE, AND EACH
ONE OF THEM HAS A DIFFERENT RECOMMENDATION FOR THE SHAPE OF
YOUR ICON. SO ADAPTIVE ICONS IS
A NEW PIECE OF TECHNOLOGY THAT WE HAVE BROUGHT TO YOU IN O
THAT ALLOWS YOU TO SAY, HERE'S MY
BACKGROUND, HERE'S MY FOREGROUND. CUT IT OUT TO
WHATEVER SHAPE YOU LIKE. SO EVEN IF THE LAUNCHER HAS A
CIRCLE OR IT'S GOT A ROUND RECTANGLE OR IT'S GOING
SOMETHING AWFUL, YOU HAVE AN ICON THAT MATCHES EXACTLY THE
LOCAL — THE LOCAL FLAVOR. THERE'S GOING TO BE A TON MORE
INFORMATION ABOUT ADAPTIVE ICONS
AT A TALK ON THURSDAY. AND DEFINITELY GO TO THAT ONE.
ALL RIGHT. LET'S TALK ABOUT SHORTCUTS AND WIDGETS, BECAUSE
LAUNCHER IS ALSO PART OF SYSTEM UI.

PREVIOUSLY TO GET
SHORTCUTS AND WIDGETS ON THE USER'S
SCREEN, THERE'S A BROADCAST FOR SHORTCUTS THAT SORT OF, KIND OF
WORKS. AND FOR WIDGETS, YOU HAVE TO BEG THE USER, PLEASE,
PLEASE, SEE IF YOU CAN FIND OUR WIDGET INSIDE THE LAUNCHER. IN O, YOU CAN NOW ACTUALLY
REQUEST ONE OF THESE THINGS TO BE PINNED TO THE USER'S
WORK SPACE USING SHORTCUT MANAGER FOR SHORTCUTS, USING
APP MANAGER FOR WIDGETS. AND THE USER THEN GETS THE
OPPORTUNITY TO SAY NO, I DON'T WANT THAT ON MY DESKTOP
OR YES I DO AND IN FACT I WILL PLACE IT EXACTLY WHERE I
WANT IT OR THEY CAN SAY SURE, I WANT TO FIND THE EXACT SPOT
FOR IT.

NOW YOU DON'T HAVE TO SEND THEM INTO THIS LONG
FLOW. IT'S SUPER CONVENIENT. LOOK AT ALL THE USERS
YOU'RE GOING TO HAVE ON YOUR WIDGETS.
[ CHEERS AND APPLAUSE ] FOR AP APPLAUSE WHEN I'M REALLY
FUTZING WITH THE CLICKER HERE. THIS WE'LL TALK ABOUT
ON THURSDAY AT 4:30. ALL RIGHT. NOTIFICATIONS,
YOU KNEW IT WAS COMING. THEY'RE SUPER USEFUL.
THEY'RE GREAT FOR GEAMENT, USERS LOVE THEM. ENGAGEMENT
THEY MAY BE A LITTLE OUT OF CONTROL.
THERE'S A LOT BEING USED IN THE NOTIFICATION STREAM RIGHT
NOW AND IT'S HARD FOR THE USER TO MANAGE THE INFLOW OF
DEMANDS ON THEIR ATTENTION. IF IT'S OUT OF CONTROL NOW
THE USER SHOULD ALWAYS BE IN CONTROL. THAT'S BEEN A
PRINCIPLE OF OURS SINCE THE BEGINNING. WEEDED THE
WE WE ADDED THE ABILITY TO BLOCK, IN NOWGHT
WE NOUGAT WE REFINED IT. BUT THE
NUMBER ONE REQUEST WE GET FROM USERS IS, OKAY, BUT CAN
I JUST BLOCK SOME OF AN APP'S NOITIONZ? ON THE OTHER HAND
THE NUMBER ONE REQUEST WE GET FROM DEVELOPERS IS COULD THE
USER JUST BLOCK SOME OF MY NOTIFICATIONS.

IT'S THE SAME
THING. EVERYBODY HAS BEEN ASKING FOR THE SAME THING.
AND THIS IS WHERE NOTIFICATION CHANNELS COME
FROM. IT'S A NEW API IN O. A CHANNEL IS A NAME CATEGORY
OF NOTIFICATIONS FROM ONE APP THAT SHARES THE SAME
BEHAVIOR. VIBRATION, SOUND, LIGHT, SO THEY POP UP ON THE
SCREEN SO THE USER HAS EXPLICIT AND FINE-GRAINED
CONTROL. [ APPLAUSE ]
SO IT'S AN APP, YOU'LL GET TO SET UP ALL THE CHANNELS,
DEFINE THE DEFAULT BEHAVIOR FOR O AND A PRIVATE MESSAGE
SHOULD POP UP AND IN O, MAYBE A TAG DOESN'T POP UP OR HAS A
LOWER PRIORITY.

AND USERS, WHEN THEY LONG PRESS A
NOTIFICATION OR USE THE NEW SLIDE GESTURE TO LOOK AT IT
THEY CAN SEE WHAT CHANNEL IT'S ON AND MAKE CHANGES
RIGHT THERE IN LINE. ONCE YOU TARGET O, IF YOU
TAKE NOTHING ELSE AWAY FROM MY TWO MINUTES HERE, TAKE
AWAY THIS, YOU HAVE TO USE CHANNELS FOR EVERY
NOTIFICATION OR THEY WILL BE DROPPED. SO UNTIL YOU TARGET
O, YOU CAN START, LIKE, SLOWLY EVOLVING YOUR
NOTIFICATION SYSTEM OVER TO CHANNELS. ONCE YOU TARGET O,
THEY HAVE TO ALL BE CHANNELIZED BECAUSE WE'RE
TRYING TO GET TO A CONSISTENT EXPERIENCE WHERE THE HEUFER
KNOWS GOING TO GET AND WOORS GOING TO
TALK ABOUT THAT AND A LOT OF OTHER GREAT STUFF, ALL THE
CODE I DIDN'T PUT UP THERE, WHATEVER THE LITTLE BLINKY
THING IS UP THERE ON THIS TALK AT 4:30 TOMORROW.
THRAZ A LOT OF THERE'S'S A LOT OF OTHER
GREAT STUFF.

IT RAN OFF HERE. I LIKE DOING THAT WITH
SLIDES. AND I ENCOURAGE YOU VERY MUCH TO CHECK OUT THE
DEVELOPER PREVIEWS AND PLAY WITH THE BETA SNAWLG
INSTALLER. WE'RE REALLY PROUD OF IT.
Romain Guy: AS DEVELOPERS, WE EXPANDED ON THE STRICT
MODE API THAT I'M SURE YOU'RE ALL USING IN YOUR DEBUGGING
SO NOW ON THE THREAD POLICY YOU CAN USE IT WHEN YOU HAVE
UNBUFFERED I/O. SO WHEN YOU HAVE A INPUT/OUTPUT, YOU'LL
GET A FLASH OR WHATEVER IT IS, THE TRIGGER WARNING YOU
SET. ON THE VM POLICY IF YOU DON'T TAG YOUR SOCKETS, YOU
CAN GET WARNED. TAGGING SOCKETS IS REALLY IMPORTANT
FOR TRAFFIC DEBUGGING IN ANDROID STUDIO. AND IF YOU
SET AN INTENT OUTSIDE YOUR APPLICATION AND YOU NEED TO
GRANT PERMISSION, YOU CAN ALSO BE WARRANTED. SO IT'S
FAIRLY EASY TO USE. IT LOOKS LIKE THE PREVIOUS APIs WE
HAD. MEDIA FILE ACCESS. SO WE
INTRODUCED A DOCUMENT PRIFERS A WHILE AGO, A COUPLE
RELEASES AGO AND THEY'RE EXTREMELY USEFUL EXCEPT WHEN
YOU HAVE LARGE DOCUMENTS. IF YOU HAVE A LARNG DOCUMENT YOU
NEED IT TO DOWNLOAD THE ENTIRE DATA BEFORE YOU CAN
PASS IT TO THE USERS OF THE DOCUMENT PROVIDER.

SO NOW
YOU CAN USE SEEKABLE FILE SCRIPTERS. IT'S USEFUL FOR
VIDEO, AUDIO OR ANY CONTENT. YOU GET THE STORAGE MANAGER,
YOU OPEN THE PROXY FILE SCRIPTER, YOU INVOKE A CALL
BACK TO REQUEST SOME AMOUNT OF DATA IN THE BAT ARRAY, AND
THEN WE'RE GOING TO TELL TELL YOU WHEN TO CLOSE IT.
CACHED DATA. SO THIS IS NEW API THAT THE SYSTEM GIVES YOU
TO BE A BETTER CITIZEN. SO EACH APP HAS A CERTAIN AMOUNT
OF DATA IT CAN USE IN THE CACHE PARTITION. AND WHEN
THE SYSTEM RUNS OUT OF SPACE, OUT OF STORAGE SPACE, IT'S
GOING TO START DELETING SOME OF YOUR CACHED DATA. SO IF
YOU STAY BELOW THE QUOTA THAT YOU'RE GIVEN, YOU CAN AVOID
YOUR DATA BEING DELETED. FOR THIS YOU CAN USE THE
STORAGE MANAGER. YOU CAN QUERY THE NUMBER OF BYTES
THAT ARE ALLOCATED TO YOUR APP. YOU SHOULD QUERY THAT
FROM TIME TO TIME BECAUSE THE QUOTA CAN CHANGE DEPENDING ON
HOW MUCH OF THE QUOTA YOU USE OR HOW OFTEN THE USER USES
THE APPLICATION. THEN WHEN YOU WANT TO ALLOCATE DATA YOU
CAN JUST USE ALLOCATE BYTES.

YOU CAN DO IT YOURSELF. YOU
CAN CREATE A FILE, CREATE AN OUTPUT STREAM BUT IT'S MUCH
BETTER TO DO IT THIS WAY BECAUSE WHEN YOU GO THROUGH
ALLOCATE BYTES IF NEEDED IT WILL DELETE ANOTHER APPS
CACHED DATA TO MAKE SPACE FOR YOUR DATA. SO THAT MEANS IT
COULD BE BIGGER THAN THE FREE SPACE THAT'S LEFT ON THE
DEVICE. YOU CAN ALSO USE SOMETHING
CALLED SET CACHE BEHAVIOR TOMBSTONE. SO THIS IS VERY
USEFUL TO — FOR YOUR APP TO BE ABLE TO TELL THE
DIFFERENCE BETWEEN A FILE THAT WAS NEVER CACHED AND A
FILE THAT WAS CACHED BUT DELETED.
SO WHEN YOU SET THAT BEHAVIOR AND THE SYSTEM DELETES SOME
OF YOUR FILES IN YOUR KAMP, CACHE
IT WILL TRUNCATE THE FILE.

SO THE FILE WILL STILL BE
THERE BUT THE SIZE WILL BE SET TO ZOA. THAT TELLS ZERO. THAT TELLS YOU
IT WAS DELETED BY THE SYSTEM. Dan Sandler: THERE'S A LOT
GOING ON IN ANDROID SECURITY IN THIS RELEASE AND WE ONLY
HAVE A LITTLE BIT OF TIME TO TALK ABOUT T I WANT TO
HIGHLIGHT SOME OF THE PRIVACY IMPROVEMENTS THAT ARE NEW IN
ANDROID O. IF YOU HAVE BEEN USING ANDROID I.D., YOU NEED
TO KNOW NOW THAT IT IS GOING TO BE DIFFERENT FOR EVERY
APP, FOR EVERY USER ON THE DEVICE. SO IT CAN'T BE USED
TO TRACK USERS BETWEEN APPS ON THE SAME DEVICE ANYMORE.
SIMILARLY, IF USB YOU'VE BEEN REFLECTING IN THE SYSTEM
PROPERTIES TO GET NET.HOST NAME, IT IS EMPTY NOW.

SO IF
YOU ARE SAYING I REALLY NEED ADVERTISING IDs TO BE ABLE
TO SEND USERS THE CORRECT CONTEXTUAL ADVERTISEMENTS,
THAT IS WHAT THE ADVERTISING ID API IN PLAY GOOGLE PLAY SFS
IS FOR SO GO CHECK IT OUT IN
GOOGLE PLAY BUT YOU CANNOT USE AN ANDROID ID. YOU CAN'T
TRUST IT ANYMORE IN THE SAME WAY YOU MIGHT HAVE DONE.
I HAD A SLIDE HERE ABOUT WEBVIEW BUT THEN ROMAIN TOOK
IT.

ONE THING I WANTED TO MENTION ABOUT SAFE BROWSING
IN WEBVIEW IS BECAUSE WEBVIEW IS NOW PUSHED TO THE PLAY
STORE EVERY SIX MONTHS YOU'LL BE ABLE TO OPT INTO SAFE
BROWSING FEATURES AS FAR ACAS BACK
AS LOLLYPOP WHICH IS FANTASTIC.
WE ALSO SAW IN THE KEYNOTE SOMETHING CALLED GOOGLE PLAY
PROTECT WHICH IS A LOT OF THE TECHNOLOGIES WE HAD IN PLACE
BEFORE BUT NOT GIVEN THE VISIBILITY THEY TRULY DESERVE
BECAUSE WE ARE WATCHING OUT FOR PEOPLE ALL THE TIME. SO
ANY APP THAT GETS UPLOADED TO PLAY IS PRESCREENED AND
CONTINUOUSLY RESCREENED FOR EACH NEW VERSION THAT'S
UPLOADED.

AND EVERY TIME YOU INSTALL AN APP WHERE YOU HAVE
PLAY PROTECT SET UP, THAT APP IS GOING TO BE SCREENED AS
WELL EVEN IF YOU GOT IT FROM ANOTHER STORE OR FROM, YOU
KNOW, ADB INSTALL. AND WE'RE REALLY EXCITED ABOUT THIS.
THERE IS SO MUCH MORE TO TALK ABOUT, SO MUCH MORE TO TALK
ABOUT IN ANDROID SECURITY, THEY GAVE ME A WHOLE, LIKE,
SLIDE DECK OF STUFF SO I SAID WHY DON'T YOU HAVE YOUR OWN
TALK. I ACTUALLY DIDN'T SAY THAT. THEY HAD THEIR OWN
TALK ANYWAY. ON THURSDAY AT WHAT'S NEW IN ANDROID
SECURITY EVERYTHING FROM SOUP TO NUTS.
Romain Guy: LANGUAGE AND RUNTIME. I THINK YOU ALREADY
KNOW WHAT I'M GOING TO SAY. SO THIS MORNING WE ANNOUNCE
OFFICIAL SUPPORT FOR KOTLIN.

[ CHEERS AND APPLAUSE ]
YOU SAW STEPH ON STAGE, AND I SEE HERE SITTING RIGHT THERE
IN THE HALLWAY. SO IF YOU SEE HER AT I/O, GO SAY
THANKS. SO STEPH AND THE WHOLE TEAM BEHIND HER DID AM
MAIGZ WORK OVER THE PAST, YOU KNOW, HOWEVER MUCH TIME TO
BRING YOU THIS. SO GO THANK HER. SHE'LL PASS YOUR THANKS
ALONG TO THE WHOLE TEAM.

SO IT'S AVAILABLE TODAY IN
ANDROID STUDIO 3.0. THERE'S A LOT OF DOCUMENTATION
ONLINE. I COULD SPEND HOURS TALKING ABOUT KOTLIN AND WHY
IT'S GOOD FOR YOU, WHY IT'S GOOD FOR US.
Chet Haase: HE DOES, IN FACT.
Romain Guy: BUT UNFORTUNATELY WE DON'T HAVE
THAT MUCH TIME IN THIS SESSION. SO INSTEAD I INVITE
YOU TO COME ON FRIDAY AT 10:30 HERE ON THIS STAGE.
THERE'S GOING TO BE A TALK CALLED INTRODUCTION TO KOTLIN
FROM ANDREY BRESLAV, THE TECH — LEAD LANGUAGE DESIGNER AT
JETBRAINS, AND HADI, VP AT JETBRAINS.
AND THEN IN THE AFTERNOON — AND THEN IN THE AFTERNOON ON
STAGE 4, WE'LL HAVE LIFE IS GREAT AND EVERYTHING WILL BE
OKAY, KOTLIN IS HERE, BY CHRISTINA LEE FROM PINTEREST
AND JAKE WHARTON FROM SQUARE.

[ CHEERS AND APPLAUSE ]
AND THIS IS IMPORTANT TO US BECAUSE THE REASON WHY WE
BROUGHT YOU KOTLIN IS BECAUSE YOU THE COMMUNITY IS USING
KOTLIN. WE LISTENED, WE HEARD YOU. WE'RE BRINGING
YOU WHAT YOU WANTED SO WE WANTED TO HAVE YOU THE
COMMUNITY ON STAGE TO TALK ABOUT IT BETTER THAN WE CAN.
ALSO, IF YOU HAVE QUESTIONS YOU CAN COME TO THE DEVELOPER
SANDBOX AT THE ANDROID CORE PLATFORM BOOTH TODAY FROM
3:00 TO 4.30 ON THURSDAY FROM TWO TO FOUR, AND ON FRIDAY
FROM NOON TO 2:00 P.M, ANDREY THE LANGUAGE DESIGNER WILL BE
THERE TO ANSWER YOUR QUESTIONS. SO ANYTHING YOU
WANT TO KNOW ABOUT KOTLIN, PLEASE GO THERE AND ASK YOUR
QUESTIONS. NOW, LIKE STEPH MENTIONED
WE'RE ALSO DOUBLING DOWN ON THE OTHER LANGUAGES, SO THE
JAVA PROGRAMMING LANGUAGE AND WE ALSO 72C AND COMPLUS SOY
FOR THE JAVA PROGRAMMING LANGUAGE WE HAVE JAVA.TIME
THAT MAKES MANIPULATING TIME AND DATES EASY AND IT MAKES
SENSE.

IT MAKES A LOT MORE SENSE THAN THE OTHER APIs.
IT'S ABOUT TIME. WE'RE ALSO BRINGING YOU JAVA.NOI.FILE.
IT IMPROVES ON THE. IT GIVES YOU THE ATTRIBUTES OF THE
FILE. IT LETS YOU EASILY MANIPULATE PATHS. WIELDS
GIVE YOU AN EXAMPLE. AND SLIGHT REFOR EXAMPLE, THIS IS
AN APPROXIMATION BUT IT'S REALLY COOL BECAUSE IT LET'S
YOU TRANSFORM AND WRAP METHOD HANDLES IN YOUR APPLICATION.
SO HERE'S AN EXAMPLE OF THE NEW FILES API. SO YOU CAN
USE THE PATH CLASS TO GET A PATH. AND THEN YOU CAN JUST
CALL FILES THAT LINES, IT WILL READ THE ENTIRE CONTENT
OF THE FILE. YOU ARE GOING TO GET A STREAM. SO IN THIS
EXAMPLE I AM USING (INDISCERNIBLE) AND STRING
STRING APIs TO REMOVE ALL THE LINES THAT START WITH THE
POUND SIGN AND I COLLECT EVERYTHING BACK INTO A SINGLE
STRING AT THE END. SO IT'S A LOT EASIER THAN IT WAS
BEFORE. Chet Haase: WE HAVE SOME
CHANGES IN RUNTIME. WE HEARD ABOUT SOME OF THESE THIS
MORNING AND. NEW CONCURRENT COPYING COLLECTOR MAKING
EVERYTHING FASTER AND BETTER. IT MEANS NO PAUSE TIME EXCEPT
WHEN THERE'S A FULL TPUS C SO IT CAN DO ALL THE STUFF IT
NEEDS TO DO THE BACKGROUND WHILE YOU'RE DOING OTHER
STUFF.

IN PARTICULAR, ONE OF THE REALLY COOL THINGS THAT
IT CAN DO IS ACTUALLY COMPACT THE HEAP IN THE FOREGROUND.
SO PREVIOUSLY IN R, I BELIEVE IN THE PREVIOUS RELEASE, IT
HAD THE ABILITY TO COMPACT THE HEAP, IT CAN MAKE THE
HEAP SMALLER, IT CAN MAKE ALLOCATIONS AND COLLECTIONS
FASTER BUT ONLY WHEN ACTIVITIES WERE IN THE
BACKGROUND. SO IT WILL GO INTO AN IDLE STATE AND DO IT
WHEN IT WAS IN THE IDLE STATE BUT WHEN IT WAS IN THE
FOREGROUND, THERE WAS NOTHING IT CAN DO.

NOW IT CAN
COLLECT AND DEFRAG IN THE FOREGROUND AND EVERYTHING IS
FASTER. THERE'S ALSO A NEW FASTER MECHANISM FOR
ALLOCATIONS SO IT CAN US J DO BUMP POINTER ALLOCATIONS
WHICH IS MUCH, MUCH FASTER. COLLECTIONS ARE FASTER AND
ALL OF THIS ESSENTIALLY RESULTS IN LESS JANK FOR YOU.
SO FASTER TO ALLOCATE STUFF, FASTER TO COLLECT STUFF MEANS
THAT JUST DEALING WITH GARBAGE AND MEMORY IN GENERAL
IS MUCH FASTER USING ART IN THE O RELEASE.
VARIOUS OPTIMIZATION SES.
DALVIK WITH REN JAITD WITH MEMORY SCYTHE TIGHT
CONSTRAINTS.

EVERYTHING WAS ABOUT SAVING MEMORY WITH
DALVIK WHICH MEANS IT CAN ONLY DO SO MUCH OPTIMIZE MIEZ
SAYINGS. WHEN ART CAME ONLINE THEY PUT IN A PLATFORM
UPON WHICH WE COULD BUILD FUTURE OPTIMIZATIONS. SO
WE'RE STARTING TO REAP THOSE BENEFITS NOW WHERE WITH EVERY
RELEASE, INCLUDING O AND FUTURE RELEASES, WE'RE GOING
TO BE ABLE TO DO MORE AND MORE. AND THERE'S A BUNCH OF
THEM IN THIS RELEASE AND YOU SHOULD CHECK OUT A SESSION
LATER IN THE WEEK FOR MORE INFORMATION ON THAT. ALSO
THERE'S DEX LOCALITY. THIS IN PARTICULAR IMPROVES LAUNCH
TIME FOR ACTIVITIES BECAUSE WE CAN COLLECT ALL THE MEMORY
IN THE SAME SPACE. SO IT'S EASIER AND FASTER TO ACCESS
AS YOU'RE APPLICATION IS STARTING UP.
SO THERE'S A SESSION ON FRIDAY MORNING, PERFORMANCE
AND MEMORY IMPROVEMENTS. SO CHECK THAT OUT FOR MORE
PARTICULARS THERE. SO BEYOND THE PLATFORM, WE
HAVE SUPPORT LIBRARY, WE HAVE OTHER MECHANISMS FOR
DELIVERING THINGS THAT AREN'T JUST ABOUT THE O RELEASE.

WE
WANTED TO CALL OUT SOME OF THOSE. THERE'S THE v26
BETA RELEASE THAT COMES OUT WITH DEVELOPER PREVIEW TWO.
THE STUFF WE ALREADY TALKED ABOUT IN TEXT. FONTS IN XML, DOWNLOADABLE FONTS AS WELL AS
AUTO SIZING TEXTVIEW. THOSE ARE ALL IN THERE. YOU CAN
CHECK THOSE OUT. IN ADDITION THERE'S SOMETHING WE CALL
MOIJ COMPAT. SO EMOJICOMPAT. ONE OF THE BIG
PROBLEMS WE HAVE WITH EMOJIS IF YOU HAVE FRIENDS SENDING
YOU SOMETHING FROM EMOJIS FROM A FUTURE STANDARD,
YOU'RE NOT GOING TO SEE THOSE AND YOU'RE GOING TO SEE TOFUS
INSTEAD. WHICH GIVEN SOME OF THE EMOJIS, MAY BE MORE
ATTRACTIVE BUT NOT VERY MEANINGFUL. SO WOULDN'T IT
BE GREAT IF YOU COULD GET UPDATED MOIDGES ON YOUR
DEVICE. SO NOW WE HAVE TWO MECHANISMS THAT DEVICES CAN
USE TO GET UPDATED EMOJIS. ONE IS IT CAN BUNDLE WITH
UPDATED MOIFNLINGS SO THEY CAN UPDATE THE APPS TO THE
PLAY STORE AND THEN TO THEIR USERS SO THE USERS GET MORE
TIMELY UPDATES OF THESE EMOJIS. THE OTHER, AND
PROBABLY BETTER CERTAINLY LONG-TERM SOLUTION, IS TO
ACTUALLY USE A SERVICE WE CAN PROVIDE THROUGH DOWNLOADABLE
FONTS WE TALKED ABOUT EARLIER WHERE THEY CAN AUTOMATICALLY
GET UPDATED FONTS THROUGH DOWNLOADABLE FONTS; RIGHT?
SO THEY CAN — THE APP CAN BUILD IN THE CAPABILITY TO
USE THE DOWNLOADABLE FONTS CAPABILITY TO HAVE UPDATED
EMOJIS AS WE PROVIDE THEM INTO THE SERVICE.
SO AGAIN, GO TO THE WHAT'S NEW IN SUPPORT LIBRARY TALK
TOMORROW MORNING TO LEARN MORE ABOUT ALL OF THOSE.
WE ALSO HAD MORE STUFF GOING ON IN ANIMATION BESIDES THE
SMALL STUFF IN ANIMATORSET I TALKED ABOUT EARLIER.

WE
HAVE THE ABILITY TO NOW HAVE PHYSICS-BASED ANIMATION
STUFF. SO IF WE WANT TO SEE THAT IN ANIMATION FORM. THE
ABILITY TO HAVE ESSENTIALLY ANIMATIONS DRIVEN THROUGH
VELOCITY, ALL THE ANIMATION ABILITIES WE HAVE IN THE
PLATFORM TO DATE HAVE BEEN DRIVEN AROUND THE IDEA OF A
DURATION. YOU TELL IT HOW LONG YOU WANT IT TO RUN FOR,
BUT MANY ANIMATIONS, YOU REALLY WANT TO DRIVE IT BY
THE VELOCITY IN PARTICULAR, ANIMATIONS THAT ARE DRIVEN BY
USER INTERACTIONS. YOU'RE DRAGGING SOMETHING ON THE
SCREEN AND YOU LET GO. WOULDN'T IT BE NICE IF IT
TOOK OFF FROM YOUR FINGER AT THE SAME VELOCITY THAT YOU
ARE WERE CRAGGING IT DRAGGING IT WHEN YOU
LET GO.

SO FLINGS, SCROLLS, ALL THAT STUFF, IT REALLY
REQUIRES A VELOCITY-BASED ANIMATION SYSTEM INSTEAD.
YOU CAN DO THAT WITH THE ANIMATORS BUT IT'S REALLY
TEDIOUS. IT REQUIRES MATH. MATH IS HARD. AND SO WE
BAKED IN THAT CAPABILITY TO THIS NEW PHYSICS ANIMATION
SYSTEM THAT IS MORE NATURAL, MORE INTERACTIVE AND MORE
INTERRUPTIBLE BECAUSE IT WAS REALLY INTENDED TO WORK WITH
THAT USER INTERACTIVITY MODEL. HERE IS A DEMO OF
THIS. SO AS WE'RE DRAGGING THE TOP THING AROUND, THE
OTHER CIRCLES ARE HINGED TO THE TOP ONE THROUGH SPRINGS
YOU DEFINE SO THEY FOLLOW IT IN SPACE. THEY'RE NOT LOCK
STEP FOLLOWING IT BUT THEY'RE BASICALLY ON SPRINGS THAT ARE
ATTACHED AND THEY IMMEDIATELY BENEFIT FROM THAT INTERACT
ACTIVITY. SO THERE'S A TALK BASED ON THIS FRIDAY
AFTERNOON, ALL ABOUT THE NEW PHYSICS BASED ANIMATION
STUFF. PLEASE COME THAT IF YOU WANT TO KNOW MORE ABOUT
THAT.

ART-BASED, THIS WAS MENTIONED
IN THE KEYNOTES. WE THOUGHT SOMETIMES ANDROID DEVELOPMENT
IS A LITTLE HARDER THAN IT NEEDS TO BE SO WE TOOK A STEP
BACK AND SAID OKAY WHAT ARE SOME OF THE MAJOR PROBLEMS WE
SHOULD TAKE ANOTHER RUN AT TO START TO SIMPLIFY THIS TO FOR
APP VERLTS AND A COUPLE OF THESE WE HAVE TAKEN RUNS AT
RIGHT NOW ARE AROUND LIFE CYCLE. IT'S APPARENTLY HARD
TO DEAL WITH THE FACT THAT YOUR ACTIVITIES CAN DIE
ANYTIME WHEN YOU ROTATE THE STREEN OR GOES IN THE
BACKGROUND OR WHATEVER AND FINDING OUT EXACTLY WHAT
STATE YOU'RE IN CAN BE A BIT TEDIOUS. IT IS AN ONGOING
ISSUE ALL APP DEVELOPERS NEED TO DEAL WITH SO WE'VE TAKEN
ANOTHER APPROACH TO THAT TO MAKE IT MUCH EASIER AND IN
ADDITION TO THAT WE'VE TAKEN A LOOK AT PERSISTENCE SO. SO
WE HAVE A NEW WAY OF DOING THAT THAT BUILDS ON THAT
CAPABILITY AND MAKES IT EASIER AND MORE POWERFUL.
AND WE'RE GOING TO YOU CAN AT THAT ABOUT ALL OF THOSE THIS
WEEK.

WE'RE GOING TO HAVE AN INTRODUCTION TO ARCHITECTURE
COMPONENTS I WOULD ENCOURAGE YOU TO GO TO THIS AFTERNOON.
THAT'S ACTUALLY IMMEDIATELY AFTER THIS SESSION. AND THEN
TOMORROW MORNING WE'RE GOING TO HAVE ONE ON THE LIFE CYCLE
PROBLEM AND HOW WE'VE SOLVED THAT AND WE'RE ALSO GOING TO
HAVE ONE ON PERSISTENCE AND OFFLINE. AND ALL OF THESE
ARE BITS THAT YOU CAN ACTUALLY TRY OUT IN AN EARLY
RELEASE FORM ALREADY. SO CHECK THOSE OUT. HOPEFULLY
IT WILL MAKE YOUR DEVELOPER LIVES EASIER.
THERE ARE SOME BEHAVIOR CHANGES SOME OF WHICH YOU'RE
GOING TO CARE ABOUT MORE THAN OTHERS. THERE HAVE BEEN SOME
CHANGES TO THE BEHAVIOR OF BACKGROUND APPLICATIONS; IN
PARTICULAR, ROGUES LOCATION. IF YOU
ARE RUNNING AS A BACKGROUND APPLICATION YOU ARE ONLY
GOING TO GET COARSE GRAINED LOCATION INFORMATION. ALL OF
THESE THINGS ARE BEING DONE NOT TO NEIGHBORING IT HARDER
BUT TO MAKE THE DEVICE BETTER. IF ALL APPLICATIONS
HAVE LOCATION AT ANY TIME AND THEY CAN DO WHATEVER THEY
WANT TO AT ANY TIME THEN ESSENTIALLY YOU'RE GOING TO
RUN THE BATTERY DOWN BECAUSE EVERYBODY USING BARYT BATTERY
ALL THE TIME.

SO WE'RE TRYING TO
BE JUDICIOUS ABOUT WHICH APPLICATION NEEDS IT AT WHAT
TIME SO YOU CAN MAKE THE EXPERIENCE FOR YOUR USERS
MUCH BETTER AS HE WILL. SO ONE OF THOSE IS IN LOCATION,
COARSE GRAINED INFORMATION WHEN YOU'RE IN THE
BACKGROUND. ANOTHER ONE IS ONEBOX. WE
WAKELOCKS. WE NOTICED IT IS COMMON FOR AN APPLICATION TO
GO INTO A CACHE STATE AND TO WOULD JUST KEEP THAT WAKELOCK
AND IT WOULD HOLD IT FOR A REALLY LONG TIME AND THAT
REALLY RUNS THE BATTERY YOU DOWN.

SO NOW SOMETIME AFTER YOU GO INTO A CACHE STATE THE
WAKELOCK IS AUTOMATICALLY RELEASED SO IT DOESN'T PUT
THE DEVICE INTO THAT UNSEEMLY STATE.
AND ALSO THERE ARE LIMITS TO EXECUTION WHEN YOU'RE RUNNING
IN THE BACKGROUND. THERE HAVE ALSO BEEN CHANGES TO
ALERT WINDOWS. IN PARTICULAR, THERE'S THIS NEW
TYPE OF WINDOW CALLED TYPE APPLICATION OVERLAY. IF YOU
ARE TARGETING THE O SDK, THEN THIS IS THE WINDOW TYPE YOU
MUST USE IF YOU WANT TO HAVE AN ALERT WINDOW CAPABILITY.
IF YOU'RE ON EARLIER RELEASES, OBVIOUSLY THAT
DIDN'T EXIST, YOU'RE NOT GOING TO USE THIS.

JUST KNOW
THAT WHATEVER WINDOW TYPE YOU'RE USING IS GOING TO BE
LAYERED UNDER ONE OF THESE TYPE OVERLAY WINDOWS BECAUSE
WE HAVE A MORE CLEARLY DEFINED LAYERING POLICY NOW
WITH THAT. THERE IS MORE INFORMATION
ABOUT THIS THIS AFTERNOON AT 5:00, BACKGROUND CHECK AND
OTHER INSIGHTS. SO PLEASE COME TO THAT IF YOU WANT TO
KNOW ALL THE DETAILS ABOUT THAT.
AND THEN FINALLY, WE PROMISED TO GET BACK TO THIS, DIDN'T
WE? Dan Sandler: WE DID. THIS
IS ONE ONE MORE THING; RIGHT? Chet Haase: SO WE WERE GOING
TO TALK ABOUT "THIS." AND I MEAN, WE HAVE TO HAVE A DRUM
ROLL, DON'T WE? HOW ABOUT LIKE A THIGH ROLL? CAN WE
HAVE A THIGH ROLL? ALL RIGHT.
Dan Sandler: THAT SOUNDS NICE.
Chet Haase: UNFORTUNATELY I'M LOOKING AT THE TIMER ON
STAGE AND I'M GOING TO SAY THAT O STANDS FOR — OH, NO,
WE'RE OUT OF TIME.

THANK YOU.!
[ APPLAUSE ]
(SINGING HAPPY BIRTHDAY).
HAPPY BIRTHDAY DEAR ROMAIN, HAPPY BIRTHDAY TO YOU.
Romain Guy: THANK YOU! [ CHEERS AND APPLAUSE ] ES [ APPLAUSE ]
Sridhar Ramaswamy: THANK YOU. GOOD AFTERNOON, EVERYBODY. MY
NAME IS SRIDHAR. THANK YOU FOR JOINING ME HERE TODAY.
IT'S REALLY GREAT TO HAVE I/O RIGHT IN OUR BACKYARD AT
SHORELINE AGAIN. IT'S A REAL HIGHLIGHT FOR ME.

I GET TO MEET OTHER ENGINEERS,
DEVELOPERS, AND PRODUCT WORLD
AND CHECK OUT ALL THE AMAZING THINGS THAT YOU ARE BUILDING.
I HAVE HAD A CHANCE TO TALK TO
SOME OF YOU. AND I'M IN AWE OF ALL THE CREATIVITY THAT iOS
SEEN. I'VE SEEN.
YOU REPRESENT THE BEST DEVELOPERS THAT ARE OUT THERE.
I'M SURE THAT THE CREATORS OF THE NEXT POKEMON GO, FLIPKART,
OR AIRBNB ARE RIGHT HERE IN THIS
AUDIENCE. BUT CREATING A SUCCESSFUL BUSINESS TAKES MORE
THAN JUST AN AWESOME PRODUCT. ALL OF YOU KNOW THAT.
I KNOW OF MANY GREAT PRODUCTS THAT, LIKE, AREN'T REALLY
AROUND BECAUSE THEY ARE NOT ABLE TO
GET ENOUGH USERS OR MAKE ENOUGH
MONEY.

SO FOR MY TEAM HERE AT GOOGLE,
OUR MISSION IS CRYSTAL CLEAR. WHAT CAN WE DO TO HELP YOU TURN
YOUR AMAZING PRODUCTS INTO PROFITABLE BUSINESSES? TODAY
WE'RE GOING TO DISCUSS THREE THINGS YOU NEED TO FOCUS ON TO
GET THERE. NUMBER ONE IS DEVELOPING
SEAMLESS PAYMENT EXPERIENCES. NUMBER TWO, EARNING MORE FROM
YOUR APPS. AND NUMBER THREE, GROWING BY FINDING MORE OF YOUR
BEST CUSTOMERS. WE'LL SHARE NEW PRODUCT
INNOVATIONS IN EACH OF THESE AREAS TO HELP YOU DELIGHT YOUR
CUSTOMERS AND MAKE YOUR BUSINESSES MORE SUCCESSFUL.
YOU'VE ALL HEARD THE SAYING, "THE CUSTOMER IS ALWAYS RIGHT." THEY ARE! CONSUMER
EXPECTATIONS ARE HIGHER THAN EVER BEFORE.
CONSUMERS ARE LOOKING FOR MORE USEFUL AND MORE DELIGHTFUL
EXPERIENCES EVERY SINGLE DAY. AND WITH BILLIONS OF MOBILE
USERS GLOBALLY, THE OPPORTUNITY IN FRONT OF US IS PRETTY
AMAZING.

BUT THE SAME IS TRUE FOR ALL OF YOUR COMPETITION,
TOO. AND PEOPLE HAVE WAY MORE CHOICE NOW THAN EVER BEFORE.
OVER 5 MILLION APPS, MANY, MANY MORE SITES THAN THAT, HUNDREDS
OF TV CHANNELS, SOCIAL MEDIA, IT
GOES ON AND ON. SO HOW ARE YOU GOING TO STAND OUT IN THIS SEA
OF AMAZING CHOICES? JIM LYSKI, THE CMO OF CARMAX,
RECENTLY PUT IT THIS WAY: CONSUMERS USED TO EVALUATE
THEIR EXPERIENCES IN SILOS. I'LL
COMPARE CARMAX AGAINST ALL OTHER
USED CAR DEALERS, AND I'LL COMPARE NORDSTROM AGAINST ALL
OTHER CLOTHING RETAILERS. LET'S GO BACK ONE SLIDE,
PLEASE, ONE SLIDE FORWARD.
BUT NOW PEOPLE ARE CLEARLY TAKING THOSE BEST EXPERIENCES
FROM ONE INDUSTRY AND DEMANDING THAT THEY RECEIVE THE SAME OR
BETTER EVERYWHERE.

IF THEY CAN ORDER A VERY SPECIFIC CUP OF
COFFEE AND GET IT EVERY MORNING,
WHY CAN'T THEY HAVE AN EXPERIENCE THAT'S BESPOKE AND
CUSTOMIZED FOR THEM WHEN THEY BUY A CAR? THAT MAKES SENSE.
WITH SO MUCH COMPETITION AND INCREASING CUSTOMER
EXPECTATIONS, YOU CAN'T WIN CUSTOMERS WITH A ONE SIZE FITS
ALL APPROACH. THIS REALLY CALLS FOR NEW
STRATEGIES THAT PUTS THE FOCUS ON EACH INDIVIDUAL CUSTOMER.
IT MEANS UNDERSTANDING YOUR
CUSTOMERS AND HOW THEY DIFFER. IT MEANS CREATING GROWTH AND
MONETIZATION STRATEGIES THAT REFLECT THOSE INSIGHTS.
AND IT MEANS USING TOOLS THAT ARE POWERFUL AND FLEXIBLE
ENOUGH TO ACT ON THAT INFORMATION.
AND THIS IS WHERE WE THINK WE CAN HELP.

ONLY GOOGLE CAN
PROVIDE YOU WITH THE TOOLS AND TECHNOLOGY THAT HELP YOU PUT
YOUR CUSTOMERS AT THE CENTER OF HOW YOU DEVELOP, EARN, AND GROW
FROM YOUR PRODUCT. TO START WITH, WE'RE HELPING
YOU DEVELOP EASIER WAYS TO PAY FOR
YOUR PRODUCTS AND SERVICES. HOW
MANY OF YOU HAVE ABANDONED A SHOPPING CART ONLINE? I DID
JUST YESTERDAY. SOMETIMES IT TAKES REALLY LONG TO CHECK OUT
OR YOU DON'T HAVE YOUR CREDIT CARD HANDY. EITHER WAY, IT'S A
PRETTY FRUSTRATING EXPERIENCE, BOTH FOR YOU, YOU DIDN'T GET
WHAT YOU WANT DONE, AND FOR THE BUSINESS THAT LOST YOUR MONEY.
PAYING ONLINE SHOULD BE EASY. AND THAT'S ONE OF THE REASONS
WHY WE'VE MADE THIS A TOP PRIORITY FOR GOOGLE. OUR OPEN
PLATFORM APPROACH MAXIMIZES THE WAY IN WHICH PEOPLE CAN PAY AND
THE WAYS YOU CAN GET PAID.

WE WANT TO PROVIDE A SEAMLESS,
CONSISTENT EXPERIENCE ACROSS DEVICES AND ACROSS PLATFORMS.
HUNDREDS OF MILLIONS OF PEOPLE HAVE ALREADY SAVED THEIR
PREFERRED PAYMENT METHOD, LIKE A
CREDIT CARD OR A DEBIT CARD, TO THEIR GOOGLE ACCOUNT. AND
TODAY WE'RE GOING TO ANNOUNCE A
DEVELOPER SOLUTION THAT WILL ALLOW PEOPLE TO USE THESE SAVED
CARDS WHEN CHECKING OUT IN YOUR APPS, SITES, AND MORE WITH JUST
ONE SINGLE BUTTON. PAYMENTS ARE A CRITICAL PART OF
THE CONVERSION PROCESS, AND WE WANT TO HELP YOU MAKE IT AS
QUICK AND AS EASY AS POSSIBLE.

AND WHEN YOU MAKE IT EASIER FOR
PEOPLE TO PAY FOR WHAT THEY WANT, YOU WIN.
IT'S REALLY THAT SIMPLE. NEXT UP, EARNING MORE FROM YOUR
APPS. WHILE SOME OF YOUR USERS MIGHT
MAKE IN-APP PURCHASES, LET'S FACE IT, THE MAJORITY NEVER
REALLY DO. AND THAT'S WHY EARNING MONEY WITH IN-APP ADS
IS THE MOST COMMON REVENUE MODEL
FOR MOBILE BUSINESSES. ADMOB HELPS YOU DO THAT.
TODAY, OVER A MILLION APPS USE ADMOB
TO MAKE MONEY ON iOS AND ON
ANDROID. IN FACT, TO DATE, WE'VE PAID OUT OVER $3.5
BILLION IN ADS REVENUE TO ADMOB
DEVELOPERS, LIKE YOU, MORE THAN ANY OTHER AD NETWORK.
AND A TRULY CUSTOMER-CENTRIC MONETIZATION STRATEGY MEANS YOU
MONETIZE DIFFERENT USER GROUPS IN DIFFERENT WAYS.

FOR THAT,
YOU NEED A SOLUTION THAT'S POWERED BY INSIGHTS, ONE THAT
OFFERS GREAT AD FORMATS, EASY-TO-USE TOOLS, AND HELPS
YOU SCALE TO MEET INCREASING GLOBAL
DEMAND. AND TODAY WE'RE GOING TO SHOW
YOU A COMPLETELY REIMAGINED ADMOB, REBUILT FROM THE GROUND
UP, BASED ON YOUR FEEDBACK TO GIVE YOU ALL OF THAT AND MORE
FOR YOUR APPS. AND LAST, BUT NOT LEAST,
GROWING YOUR USER BASE. FINDING
VALUABLE USERS ISN'T EASY. LET ME EXPLAIN.

I STILL LOVE
PLAYING WORDS WITH FRIENDS. I KNOW! AND PART OF WHAT I LOVE
ABOUT THE APP IS THAT MY WIFE AND I PLAY AGAINST EACH OTHER
PRACTICALLY EVERY DAY. USUALLY HAVE MULTIPLE GAMES GOING ON ON
ANY GIVEN MOMENT. AND AFTER PLAYING A TURN IN ONE GAME, YOU
HAVE TO VIEW AN AD BEFORE BEING ABLE TO PLAY A TURN IN ANOTHER
GAME. MY WIFE, WHO IS BLESSED WITH A
LOT OF PATIENCE, WILL WAIT BETWEEN EACH GAME. ON THE
OTHER HAND, I PAID FOR THE PREMIUM
VERSION OF THE GAME THAT LET ME SWITCH BETWEEN UNLIMITED GAMES. MY WIFE AND I ARE TWO USERS WHO
INTERACT WITH APPS IN VERY DIFFERENT WAYS, BOTH VALUABLE
BUT QUITE DIFFERENT.

AND AS A DEVELOPER, YOU NEED TO
VALUE US DIFFERENTLY. TO THAT END, YOU NEED A MARKETING TOOL
THAT KNOWS AND CAN HELP YOU PAY THE RIGHT AMOUNT WHEN ACQUIRING
NEW CUSTOMERS WHO ARE LIKE ME OR
LIKE MY WIFE. THAT'S WHY WE INTRODUCED
UNIVERSAL APP CAMPAIGNS, WE CALL
IT UAC FOR SHORT. UAC MAKES IT EASY TO FIND USERS WHO NOT ONLY
INSTALL YOUR APP BUT ACTUALLY TAKE ACTIONS WITHIN THE APP.
UAC REACHES USERS ACROSS iOS AND ANDROID ON EACH OF GOOGLE'S
BILLION-USER PROPERTIES LIKE GOOGLE PLAY, GOOGLE SEARCH,
YOUTUBE, GMAIL, AS WELL AS THE MILLIONS OF SITES AND APPS THAT
ARE ON OUR DISPLAY NETWORK. AND RATHER THAN HAVING TO
MANAGE MULTIPLE CAMPAIGNS AND MANUALLY
OPTIMIZING EACH ONE ACROSS THESE
CHANNELS AND CONTEXTS, UAC DOES THIS AUTOMATICALLY WITH ONE
SINGLE CAMPAIGN. IT USES MACHINE LEARNING, AND
AI, TO IMPROVE AND MAKE YOUR CAMPAIGN SMARTER WITH EVERY
SINGLE APP. AND IT LEARNS FROM COUNTLESS SIGNALS LIKE WHERE
PEOPLE ARE ENGAGING MOST WITH YOUR APP AND WHICH CREATIVE
WORKS BEST, ALL IN REALTIME.

AND WITH OVER HALF A DOZEN
BILLION-USER PROPERTIES, WE HAVE
THE POWER TO FIND YOUR USERS WITH BOTH SIMPLICITY AND
MASSIVE SCALE. AND IT'S WORKING.
AT I/O LAST YEAR WE ANNOUNCED THAT OUR APP ADS HAD DELIVERED
OVER 2 BILLION APP INSTALLS. THIS YEAR, I'M PRETTY EXCITED
TO SHARE THAT THIS HAS GROWN BY A
FACTOR OF 2.5 TO OVER 5 PLUS BILLION APP INSTALLS.
BETTER YET, WE'RE NOW HELPING ADVERTISERS DRIVE OVER 3
BILLION IN-APP ACTIONS PER QUARTER.
THESE ARE REAL PEOPLE TAKING REAL ACTIONS INSIDE YOUR APP.
UNIVERSAL APP CAMPAIGNS ARE TRANSFORMING THE WAY DEVELOPERS
AND MARKETERS REACH AND ACQUIRE THE RIGHT USERS, AND WE TRULY
THINK THIS IS THE FUTURE OF APP GROWTH.
AND TO DELIVER MORE VALUE TO DEVELOPERS AND MARKETERS, WE
ARE BUNDLING ALL FUTURE APP GROWTH
INNOVATIONS RIGHT INTO UAC, MAKING IT A ONE-STOP SHOP TO
GET STUFF DONE.
I'M AN ENGINEER. I'M REALLY PROUD OF THESE NEW INNOVATIONS. AND I'M EXCITED ABOUT HOW THEY
CAN HELP YOU UNDERSTAND AND BETTER SERVE YOUR CUSTOMERS IN
ORDER TO STAND OUT IN WHAT'S A REALLY COMPETITIVE ECOSYSTEM.
SO WITH THAT, I'D LIKE TO BRING UP MY TEAM TO DIVE DEEPER INTO
THESE INNOVATIONS.

AND WE'RE GOING TO KICK IT OFF WITH PALI
BHAT. THANK YOU. [ APPLAUSE ] Pali Bhat: THANKS, SRIDHAR.
HELLO, EVERYONE. I'M PALI, AND I'M THE PRODUCT LEAD FOR
PAYMENTS AT GOOGLE. TODAY I WANT TO SHARE HOW YOU CAN MAKE
IT EASY FOR YOUR CUSTOMERS TO PAY FOR YOUR PRODUCTS AND
SERVICES WHILE GIVING THEM A DELIGHTFUL EXPERIENCE.
NOW, YOUR CUSTOMERS EXPECT TO ENGAGE WITH YOU WHEREVER THEY
ARE, WHETHER IT'S ON YOUR MOBILE
WEB SITE OR ON YOUR APP OR IN THE FUTURE THROUGH THE
ASSISTANT.

NOW, ACROSS ALL THESE SURFACES,
THEY EXPECT CHECKOUT TO BE FAST AND EASY. UNFORTUNATELY, THE
CHECKOUT SCREEN IS A SINGLE BIGGEST SOURCE OF FRICTION IN
THE PURCHASE EXPERIENCE TODAY. IN FACT, THE PROBLEM IS EVEN
MORE ACUTE ON MOBILE WHERE CONVERGENCE ARE A FULL 1/3
LOWER RELATIVE TO DESKTOP. AND A
LARGE REASON FOR THAT IS BECAUSE
THE EXISTING DESKTOP CHECKOUT EXPERIENCE, WHICH HAS BEEN
OPTIMIZED OVER A PERIOD OF 20 YEARS, SIMPLY DOESN'T WORK
WELL ON MOBILE. NOW, LAST YEAR WE ANNOUNCED OUR
FIRST SET OF SOLUTIONS TO THIS COMPLEX ISSUE WITH ANDROID PAY
SERVING AS YOUR PASSPORT TO GIVE
YOUR CUSTOMERS A STREAMLINED CHECKOUT EXPERIENCE. WE HAVE
SEEN TREMENDOUS PROGRESS OVER THE LAST TEN MONTHS WITH
ANDROID PAY NOW BEING AVAILABLE IN TEN
MARKETS AROUND THE WORLD. I'M EXCITED TO ANNOUNCE THAT WE
ARE GOING TO BE BRINGING ANDROID
PAY TO EVEN MORE MARKETS OVER THE NEXT FEW MONTHS, INCLUDING
BRAZIL, CANADA, RUSSIA, SPAIN, AND TAIWAN. [ CHEERS AND APPLAUSE ] WE HAVE ALSO SEEN TREMENDOUS
MOMENTUM ON THE APP SIDE WITH THOUSANDS OF TOP DEVELOPERS
HAVING ADOPTED ANDROID PAY TO DELIVER A SEAMLESS CHECKOUT
EXPERIENCE FOR THEIR USERS.

BUT WE HAVE THE OPPORTUNITY TO
BRING THIS EXPERIENCE TO EVEN MORE USERS, AND WE CAN DO THAT
IN PARTNERSHIP WITH ALL OF YOU IN THE PAYMENTS ECOSYSTEM. SO
I'M EXCITED TO SHARE ONE OF THE FIRST COLLABORATIONS THAT IS
GOING TO DELIVER A VERY, VERY MEANINGFUL NUMBER OF USERS A
MUCH, MUCH BETTER CHECKOUT EXPERIENCE. WE'VE DONE THIS IN
COLLABORATION WITH OUR FRIENDS AT PAYPAL WHERE PAYPAL USERS
ARE GOING TO GET THE STREAMLINED
ANDROID PAY EXPERIENCE SIMPLY BY
LINKING THE PAYPAL ACCOUNT TO ANDROID PAY. SO VERY EXCITED
ABOUT THIS. SO LET ME SHOW YOU HOW THIS IS
GOING TO WORK ON THE MOBILE WEB.
SO THINKING THROUGH WHAT I'M GOING TO SHOW YOU ALL IN TERMS
OF, LIKE, BUYING SOMETHING, USING PAYPAL AND ANDROID PAY IN
ACTION, I THOUGHT OF MY 8-YEAR-OLD. EARLIER THIS WEEK
HE HAD A "DRESS YOUR COLOR" DAY AT SCHOOL. "DRESS YOUR COLOR"
MEANS YOU HAVE TO PICK YOUR FAVORITE COLOR AND WHERE YOUR
ENTIRE OUTFIT IN THAT COLOR.

HIS FAVORITE COLOR IS BLUE. SO
HE HAD ON BLUE JEANS. HE HAD A BLUE TOP. HE HAD A BLUE
HOODIE. AND, OF COURSE, BECAUSE IT
WASN'T BLUE ENOUGH, HE EVEN HAD A HOMEMADE BLUE CAPE. THE ONLY
THING THAT WAS MISSING WAS BLUE SHOES. SO I FIGURED I WOULD
SURPRISE HIM AND BUY HIM SOME BLEW SHOES TODAY ON NIKE.COM.
LET ME SHOW YOU HOW THIS WORKS. LET ME SWITCH TO THE PHONE,
PLEASE, FOR PAYPAL. WONDERFUL.
SO I'M GOING TO BRING UP NIKE.COM ON THE CHROME BROWSER. AND I'VE ALREADY PICKED OUT THE
SHOES. I'VE GOT SOME SUEDE BLUE
SHOES. WHEN I'M READY TO CHECK OUT, I'M GOING TO CHECK OUT
WITH PAYPAL AS USUAL. AND YOU'LL
NOTICE THAT THAT GETS ANDROID PAY GOING.

AND INSTEAD OF
HAVING TO HAVE TO ENTER MY USER NAME OR PASSWORD, ALL I NEED TO
DO IS USE MY FINGERPRINT, AUTHORIZE, AND I'M DONE.;
RIGHT? NO MORE ENTERING YURN USERNAMES OR
PASSWORDS OR HAVING TO CREATE AN
ACCOUNT. YOU SIMPLY HAVE TO USE
YOUR FINGERPRINT. NOW, THIS EXPERIENCE IS GOING TO BE
COMING TO MANY OF THE PAYPAL'S
MILLIONS OF SITES OVER THE COMING FEW
MONTHS AND EVENTUALLY ROLL OUT TO ALL OF THEIR SITES THAT HAVE
IMPLEMENTED PAYPAL. NOW, LET'S SWITCH BACK TO THE SCREEN.
THE SLIDES, PLEASE.
CAN YOU SWITCH BACK TO THE SLIDES, PLEASE? HMM.
AWESOME. WE WANT TO BRING THE SAME
EXPERIENCE TO VISA CHECKOUT AND MASTERPASS USERS. VERY EXCITED
ABOUT THAT. AS EXCITED AS WE ARE WITH ALL OF THE PROGRESS
THAT WE'VE SEEN IN ANDROID PAY, WE KNOW THAT OUR OVER 1 BILLION
PLUS GOOGLE USERS DON'T ALL HAVE
ANDROID PAY. OR FOR THAT MATTER, ANY DIGITAL WALLET.
HOWEVER, THESE GOOGLE USERS FREQUENT POPULAR GOOGLE
PRODUCTS LIKE GOOGLE PLAY AND YOUTUBE,
AND AS SRIDHAR MENTIONED HAVE SAVED HUNDREDS OF MILLIONS OF
CREDIT CARD AND DEB AT THIS TIME
CARDS TO THEIR GOOGLE ACCOUNTS.

SO TODAY WE WANT TO ANNOUNCE A
SIMPLE API FOR ALL OF YOU DEVELOPERS OUT THERE TO BE ABLE
TO ACCEPT ALL OF THESE PAYMENT METHODS THROUGH GOOGLE.
AND DEVELOPERS WHO ADOPT THIS API CAN ENABLE AN EASY-TO-USE
CHECKOUT EXPERIENCE FOR THEIR CUSTOMERS. AND, OF COURSE, AS
WE DISCUSSED EARLIER, REDUCE THE
AMOUNT OF FRICTION WHICH CAN LEAD TO HIGHER CONVERGENCE AND
MORE REVENUES. BEST OF ALL, THIS NEW DEVELOPER API, WHICH
WE CALL THE GOOGLE PAYMENT API, IS
GOING TO BE FREE FOR DEVELOPERS.
[ APPLAUSE ]
NOW, USERS DON'T NEED TO DO ANY ADDITIONAL SETUP IF THEY'VE
ALREADY SAVED THEIR PAYMENT METHOD TO GOOGLE. THEY SIMPLY
SIGN IN AND GET THIS STREAMLINED
CHECKOUT EXPERIENCE. NOW, WE'VE
BUILT THIS GOOGLE PAYMENT API ON
TOP OF THE PAYMENT REQUEST STANDARD WHICH IS NOW A W3C
SPEC. NOW, DEVELOPERS CAN SIMPLY ADD
THIS PAYMENT GOOGLE BUTTON TO THEIR FAVORITE WEB SITES OR
APPS BY INTEGRATING WITH THE GOOGLE
PAYMENT API. I WANT TO SHARE WITH YOU A
LITTLE STORY ABOUT THIS PAYMENT GOOGLE BUTTON THAT YOU SEE
HERE.

THIS BUTTON IS VERY SIMILAR TO
THE SIGN-IN WITH GOOGLE BUTTON THAT USERS ARE ALREADY USED.
TO. AND OUR TEAM WAS BRAINSTORMING
ALL OF THE DIFFERENT VARIATIONS THAT WE COULD POSSIBLY HAVE ON
THIS BUTTON, AND ONE OF MY ABSOLUTE FAVORITE VARIANTS WAS
"TREAT YOURSELF WITH GOOGLE." [ LAUGHTER ]
NOW, WE DIDN'T LAND ON THAT, BUT
I THINK WE'VE GOT A REALLY GOOD ALTERNATIVE WITH "PAY WITH
GOOGLE." SO SPEAKING OF TREATING MYSELF,
I WANTED TO BUY SOME COOL NEW HEADPHONES.

AND WISH IS
EXACTLY THE PLACE TO GET IT. SO WE'VE
BEEN DOING SOME WORK WITH OUR FRIENDS OVER AT WISH TO ENABLE
THIS COOL PAYMENT GOOGLE EXPERIENCE. LET ME SHOW YOU
HOW IT WORKS WITHIN THE APP.
CAN WE SWITCH TO THE WISH PHONE,
PLEASE? THANK YOU.
SO LET ME BRING UP THE WISH APP.
I'VE ALREADY ADDED THE COOL BLACK HEADPHONES THAT I WANTED
TO MY CART.

AND WHENEVER I'M
READY TO PAY, I SIMPLY NEED TO PICK MY FORM OF PAYMENT AND
HERE'S THE SPECIAL PART; RIGHT? METHODS ALREADY ATTACHED TO MY
GOOGLE ACCOUNT. YOU SEE THAT PAYPAL ACCOUNT THAT I JUST USED
TO BUY THOSE COOL BLUE SHOES, I HAVE THAT. I HAVE THE
MASTERCARD THAT I HAVE ADDED TO ANDROID PAY AND, OF COURSE, I
HAVE MY AMERICAN EXPRESS THAT I HAVE SAVED TO MY GOOGLE
ACCOUNT. SO I'M GOING TO CONTINUE AND
THAT'S IT. I SLIDE TO PAY.; RIGHT? I DON'T NEED TO ENTER
ANY USERNAMES, REMEMBER PASSWORDS, OR HAVE TO CREATE A
NEW ACCOUNT ON THE WISH SITE. PAY WITH GOOGLE MAKES IT THAT
SIMPLE. NOW, THE WISH TEAM IS GOING TO BE ROLLING OUT THIS
"PAY WITH GOOGLE" EXPERIENCE TO ALL OF THEIR USERS IN THE
COMING WEEKS. BUT WE'VE ALSO BEEN
WORKING WITH A LOT OF THE TOP DEVELOPERS TO ENABLE THIS PAY
WITH GOOGLE EXPERIENCE TO MORE USERS. SO LET'S SWITCH TO THE
SLIDES, PLEASE. SO I'M EXCITED TO ANNOUNCE
THAT WE ARE SOON GOING TO HAVE
AIRBNB, DELIVEROO, DOORDASH, AND
E24, INTEGRATED WITH THE PAY WITH GOOGLE EXPERIENCE, AND
MANY MORE DEVELOPERS ARE GOING TO BE COMING SOON.
SO AS YOU SAW, THIS EXPERIENCE IS SOMETHING THAT'S GOING TO BE
AVAILABLE NOT JUST IN THE UNITED
STATES, BUT ALSO INTERNATIONALLY.

SO WE'RE VERY
EXCITED ABOUT THAT. AND IF YOU'RE INTERESTED IN
THIS API, YOU CAN SIGN UP FOR EARLY
ACCESS. SO THAT WAS PAY WITH GOOGLE, IN
ACTION ACROSS BOTH THE MOBILE WEB AND WITHIN APPS.
BUT WE ALSO TALKED ABOUT HOW THE
ASSISTANT IS GOING TO BE A HUGE NEW PLATFORM FOR COMMERCE.
SO ONE OF THE THINGS WE'VE DONE IS WORK CLOSELY WITH THE
ASSISTANT TEAM TO BRING THE SAME
GREAT PAY WITH GOOGLE EXPERIENCE
TO THE GOOGLE ASSISTANT.

NOW, IF YOU WERE AT THE
KEYNOTE, I THINK YOU MIGHT HAVE SEEN A
DEMO ALREADY OF HOW THIS ORDERING EXPERIENCE WOULD LOOK
ON PANERA. NOW, LET'S SEE THAT DEMO IN ACTION AGAIN.
SO LET'S SWITCH TO THE DEMO THAT
WE HAVE. FOR THE ASSISTANT. AND NOW, I'M GOING TO BE TRYING
THIS ON THE ASSISTANT. IT'S A LITTLE BIT NOISY IN HERE, SO IF
EVERYONE CAN BEAR WITH ME AND KEEP REAL QUIET, WE'RE GOING TO
DO THIS LIVE. OKAY? SO I'M GOING TO BRING UP THE ASSISTANT AND THEN TRY TO ORDER
A SANDWICH AND SOME SMOOTHIES FROM PANERA.
YOU YOU HAD. Google: THESE CAME BACK FROM A SEARCH.
Pali Bhat: TALK TO PANERA.

Google: I FOUND A COUPLE OF
PLACES. Pali Bhat: I THINK IT'S A BIT
NOISY. SO I'M GOING TO TRY AGAIN.
TALK TO PANERA. Google: I FOUND A COUPLE OF
PLACES. Pali Bhat: MM.
FEELS LIKE WE HAVE A LOT OF NOISE IN HERE. MAYBE WE CAN
ALL DO IT TOGETHER.
LET ME TRY ONCE MORE, 'CAUSE THIS DEMO IS REALLY COOL.
TALK TO PANERA. Google: I FOUND A COUPLE OF
PLACES. Pali Bhat: AHH!
THE DEMO GODS ARE NOT SMILING ON
US. SO, YOU KNOW, WE'RE GOING TO
GIVE IT ONE MORE SHOT, BECAUSE ALL OF YOU, I THINK, WILL BE
INTERESTED IN THIS. AND THEN WE'LL SWITCH TO A COOL VIDEO WE
HAVE IN CASE THIS EXACTLY HAPPENED.
TALK TO PANERA. Google: I FOUND A COUPLE OF
PLACES. Pali Bhat: SO YOU KNOW WHAT?
WHY DON'T WE ACTUALLY SWITCH TO THE VIDEO, AND I'LL SHOW YOU A
LITTLE BIT OF HOW THIS WORKS ON THE VIDEO.
SO THE COOL THING ABOUT THIS IS,
IF YOU'RE ACTUALLY IN A LESS NOISY ENVIRONMENT THAN THE
SHORELINE AMPHITHEATER, WHICH HOPEFULLY NOT MANY OF YOU ARE
TRYING TO ICANN USE THE ASSISTANT IN, THEN YOU CAN
ACTUALLY GET THIS EXPERIENCE WHERE YOU CAN INTERACT WITH THE
ASSISTANT ACROSS BOTH VOICE OR BY INTERACTING WITH YOUR TOUCH
SCREEN.

AND THE COOL THING ABOUT IT IS,
YOU CAN SWITCH SEAMLESSLY BETWEEN BOTH THE VOICE AND
USING THE PROMPTS THAT THE ASSISTANT
GIVES YOU. SO IN THIS PARTICULAR EXAMPLE,
I COULD ACTUALLY START ORDERING,
LET'S SAY, THE STRAWBERRY POPPY SEED SALAD WITHOUT CHICKEN, AND THEN SWITCH TO PICKING OUT MY
FAVORITE SMOOTHY, AND THEN CHECKING OUT.
AND WHAT WE'VE DONE IS INTEGRATED THE PAY WITH GOOGLE EXPERIENCE INTO THE ASSISTANT,
SO DEVELOPERS LIKE YOU CAN HAVE A SEAMLESS EXPERIENCE FOR ALL
OF YOUR CUSTOMERS.
AND, OF COURSE, JUST LIKE YOU SAW WITH BOTH THE PAYPAL
PURCHASE I SHOWED YOU AND THE WISH PURCHASE I SHOWED YOU, I
SIMPLY CONFIRM WITH A FINGERPRINT, AND YOU'RE DONE.
SO WE'RE VERY EXCITED ABOUT ALL OF THESE NEW EXPERIENCES THAT
WE ARE BRINGING TO DEVELOPERS LIKE
YOU. SO WE LOOK FORWARD TO SEEING ALL OF YOU INTEGRATING
PAY WITH GOOGLE INTO YOUR WEB SITES, APPS, OR EXPERIENCING IT THROUGH THE ASSISTANT.
WITH THAT, I'D LIKE TO WELCOME SISSIE HSIAO, WHO'S GOING TO
TELL YOU A LITTLE BIT MORE ABOUT
HOW YOU CAN MONETIZE AND GROW YOUR APPS.
THANK YOU. [ APPLAUSE ] Sisie Hsiao: HI, EVERYONE. MY
NAME IS SISSIE, AND I AM SUPER EXCITED TO BE HERE TODAY TO
SHARE WITH YOU HOW GOOGLE WILL HELP YOU BUILD A MORE
SUCCESSFUL MOBILE APPS BUSINESS.
AS SRIDHAR TALKED ABOUT EARLIER,
THERE ARE OVER 5 MILLION APPS ACROSS ANDROID AND iOS.

AND
IF I TELL YOU THAT THE VAST MAJORITY ARE FREE, I'M SURE
MOST OF YOU WON'T BE SURPRISED.
SO WHAT DOES IT MEAN FOR YOU, TRYING TO BUILD A GREAT
BUSINESS THAT USERS WANT BOTH FREE AND
AMAZING APPS? IT MEANS THAT YOU NEED TO THINK
VERY CREATIVELY ABOUT HOW TO MONETIZE YOUR APPS AND MAKE
SURE THAT YOU'RE USING EVERYTHING IN
YOUR ARSENAL, INCLUDING IN IN-APP PURCHASES,
SUBSCRIPTIONS, AND NOW, INCREASINGLY,
ADVERTISING. THOSE OF YOU WHO ARE USING
ADMOB KNOW THAT PUTTING IN-APP ADS IS
A PRIMARY AND EFFECTIVE WAY TO MONETIZE YOUR APPS.

AND WE AT
GOOGLE HAVE BEEN FOCUSED ON CONNECTING YOU TO MILLIONS OF
GOOGLE ADVERTISERS AND OVER 40 AD NETWORKS.
BUT JUST PUTTING ADS INTO YOUR APPS ISN'T ENOUGH. HOW DO YOU
BUILD A PRODUCT THAT DELIGHTS YOUR USERS WITH ADS EXPERIENCES
THAT ARE JUST AS GOOD? IN ORDER TO BE SUCCESSFUL, YOU
NEED TO BE AS THOUGHTFUL ABOUT PUTTING ADS INTO YOUR APP AS
THE CORE USER EXPERIENCE ITSELF.
LET'S TAKE A MAJOR GAME DEVELOPER, ZEPTOLAB. I THINK
THEY MADE CUT THE ROPE, WHICH I'M SURE MOST OF YOU HAVE
PLAYED AT ONE POINT IN TIME. AND THEY
HAVE A NEW AWESOME GAME CALLED CATS. THEY'VE BEEN USING THE
ADMOB PLATFORM FOR OVER FIVE YEARS TO MONETIZE THEIR APPS.
AND THEY USE OUR FULL SUITE OF FORMATS, INCLUDING
INTERSTITIALS, REWARDED VIDEO ADS, AND NOW NATIVE ADVANCED.
AND WHEN THEY'RE DOING THAT ADVERTISING, THEY'RE VERY, VERY
CAREFUL TO MAKE SURE THAT THE ADS ARE NATIVE TO THE GAME AND
THAT THEY'RE BLENDING SEAMLESSLY
SO THAT USERS WHO ARE PLAYING ARE STILL HAVING A DELIGHTFUL
AND FUN EXPERIENCE AND IT'S WORKING FOR THEM.
SINCE THEY'VE ADDED REWARDED AD UNITS TO CATS, THEY HAVE MORE
TRIPLED THEIR ADMOB REVENUE IN THE PAST FEW MONTHS.
ZEPTO LABS IS JUST ONE EXAMPLE.

APPS USING ADMOB ACROSS ANDROID
AND iOS TO MONETIZE THEIR APPS. AND WE HAVE PAID OUT
MORE THAN $3.5 BILLION TO DATE TO
APP DEVELOPERS, MORE THAN ANY AD
NETWORK. BUT WE KNOW YOU NEED MORE.
WE'VE BEEN LISTENING TO YOUR FEEDBACK VERY CLOSELY, AND
WE'VE HEARD THAT YOU NEED MORE FROM
THIS PRODUCT. YOU NEED THREE THINGS.
NUMBER ONE, YOU WANT A HOLISTIC PICTURE OF YOUR REVENUE, NOT
JUST ADS, BUT HOW DOES ADS RELATE TO THE OTHER REVENUE
STREAMS, LIKE IN-APP PURCHASES AND SUBSCRIPTIONS.
NUMBER TWO, YOU WANT INTEGRATED APP ANALYTICS. YOU WANT TO SEE
HOW ADS WORKS AND HOW THEY AFFECT THE CORE USER EXPERIENCE
OF YOUR APP ITSELF. AND, FINALLY, NUMBER THREE, YOU
WANT BETTER AND MORE POWERFUL TOOLS TO MANAGE AND MAXIMIZE
YOUR REVENUE. BECAUSE OF THESE NEEDS, THAT'S
WHAT SPURRED MY ENGINEERING TEAM
TO EMBARK ON A MISSION AND REBUILD ADMOB FROM THE GROUND
UP. AND THAT'S WHY TODAY I AM
INCREDIBLY EXCITED TO SHARE WITH
YOU THE LAUNCH OF A COMPLETELY REBUILT, REIMAGINED ADMOB.
[ APPLAUSE ] THANK YOU.

WE WANTED TO GIVE YOU THE TOOLS
YOU NEED TO BUILD A SUCCESSFUL MOBILE APPS BUSINESS. AND
WE'RE FOCUSED ON BUILDING AN
END-TO-END MONETIZATION PLATFORM
THAT WORKS FOR YOU. OUR GOALS HERE ARE PRIMARY
TWOFOLD. NUMBER ONE, WE WANT TO
GIVE YOU DEEPER INSIGHTS INTO HOW YOUR ADS BEHAVE AND HOW
THEY AFFECT THE REST OF YOUR CORE
APP. AND I'LL SHOW YOU THAT IN A SECOND.
AND NUMBER TWO, WE BUILT ADVANCED CONTROLS SO THAT YOU
CAN — AND REPORTING, SO THAT YOU CAN MAXIMIZE AND OPTIMIZE
YOUR ADS REVENUE. AND, FINALLY, WE BUILT ALL OF
THESE FEATURES ON A CLEAN AND MODERN, REDONE USER INTERFACE.

HOWEVER, INSTEAD OF JUST TALKING
ABOUT IT, LET ME SHOW YOU A FEW SCREENS FROM THE REAL —
REALLY NEW ADMOB.
LET ME STORY TELL FOR A SECOND. AT
A MID-SIZED COMPANY, BUILDING HEALTH AND FITNESS APPS. AND
WHEN I FIRST LOG INTO THE NEW ADMOB, I SEE A COMPLETELY
DIFFERENT USER EXPERIENCE. AND WHAT I SEE HERE IS A HOME
DASHBOARD. THIS HOME DASHBOARD IS A QUICK SNAPSHOT OF ALL THE
APPS IN MY ADMOB ACCOUNT. AND IT'S TELLING ME IMPORTANT
INFORMATION ABOUT HOW MUCH I'M MAKING IN EACH OF THESE APPS
ACROSS MY ENTIRE BUSINESS. IF YOU SEE AT THE TOP, I'M
SHOWING A NEW SCORECARD, WHICH IS TELLING ME HOW MUCH I'VE
MADE TODAY, THIS WEEK, YESTERDAY,
THIS WEEK, AND THIS MONTH.

SO IT SEEMS TO BE A REALLY USEFUL
WAY FOR ME TO CHECK HOW MY BUSINESS IS DOING.
IF I SCROLL DOWN, I'M GOING TO SEE A NEW CARD ON THE LEFT
CALLED THE APP PERFORMANCE CARD.
AND HERE, WE'RE BREAKING OUT EACH OF THE APPS IN THIS
ACCOUNT AND TELLING ME HOW MUCH MONEY
I'M MAKING ACROSS MY BUSINESS. IF I LOOK CAREFULLY, THOUGH, IT
LOOKS LIKE FITMOBBER, WHICH IS MY BEST APP, HAS BEEN TANKING.
IT'S DROPPED OVER $200 YESTERDAY, WHICH IS A DISASTER,
BECAUSE THIS IS THE ONE THAT'S GROWING THE BEST. I NEED TO
FIGURE OUT EXACTLY WHAT'S GOING ON.
I DIG IN, I DRILL IN AND CLICK ON THAT. AND LET ME JUMP OUT
OF STORY FOR A SEC TO EXPLAIN WHAT
YOU'RE SEEING NOW. YOU'RE NOW SEEING A COMPLETELY
NEW APP OVERVIEW DASHBOARD. AND
THIS APP OVERVIEW DASHBOARD IS A
DASHBOARD DESIGNED TO SHOW YOU EXACTLY WHAT'S GOING ON WITHIN
A PARTICULAR APP. IN THIS CASE,
IN OUR DEMO, THIS IS THE FITMOBBER APP.

AND YOU CAN SEE
ON BOTH THE LEFT-HAND AND THE TOP THAT IT'S SHOWING YOU THAT
ALL THE NUMBERS YOU'RE SEEING ARE RELATED TO FITMOBBER.
AND FURTHERMORE, IN THE MIDDLE, I SEE TWO NEW REPORTS. ON THE
LEFT, WITH THE COLORED BARS, A TOTAL REVENUE REPORT. AND THIS
IS SHOWING ME NOT JUST ADS REVENUE FROM ADMOB. IT'S ALSO
LAYERING IN IN-APP PURCHASES, SUBSCRIPTIONS, OR OTHER IN-APP
MONETIZATION MODELS RIGHT INTO THAT BAR CHART, SO YOU CAN SEE
AT A GLANCE HOW MY OVERALL REVENUE IS TRENDING ACROSS ALL
OF THESE DIFFERENT REVENUE STREAMS.
ON THE RIGHT, I SEE ALSO A COMPLETELY NEW USER METRICS
CARD. AND THIS CARD IS SHOWING ME IMPORTANT HEALTH METRICS OF
MY CORE APP, INCLUDING SESSIONS AND RETENTION.
WHAT WE'VE DONE TO ENABLE THIS IS WEAVE TOGETHER GOOGLE
ANALYTICS FOR FIREBASE DIRECTLY INTO THE CORE OF ADMOB. WE
KNOW THAT ADS ARE A CRITICAL PART OF
YOUR USERS' EXPERIENCE.

YOU CANNOT BUILD AN AMAZING APP
WITHOUT UNDERSTANDING HOW ADS BEHAVE IN THE APP. AND YOU
CAN'T MONETIZE WELL WITHOUT UNDERSTANDING HOW USERS BEHAVE
IN YOUR APP. SO FOR THE FIRST TIME EVER,
ADMOB AND FIREBASE CAN SHARE DATA ACROSS THESE TWO PLATFORMS
TO HELP YOU GAIN DEEPER INSIGHTS
AND BUILD A MORE SUCCESSFUL MOBILE APPS BUSINESS.
COOL. LET ME GET BACK TO MY STORY AND TELL YOU HOW I CAN
USE THIS TO FIX MY FITMOBBER ISSUE.
SO IF I LOOK AT THESE NUMBERS ON
THE LEFT, IT LOOKS LIKE THE BLUE
BARS HAVE BEEN SHRINKING.

AND THE BLUE BARS ARE ACTUALLY MY
ADS REVENUE. SO THAT MAKES SENSE. THAT'S WHY I SAW THE
$200 DROP YESTERDAY. AND IF I LOOK ON THE RIGHT,
USER METRICS HAVE ALSO TAKEN A TURN
FOR THE WORSE. IN FACT, SESSIONS PER USER AND SESSION
DURATION ARE BOTH DOWN. THAT MEANS THAT USERS ARE USING THE
APP LESS AND WALKING AWAY MORE. I GO TALK TO MY TEAM AND ASK
THEM WHAT IS GOING ON. AND I LEARN THAT THEY PUT A NEW AD
UNIT RIGHT AT THE SCREEN IN THE APP THAT IS RIGHT BEFORE USERS
WORK OUT, WHICH MEANS THAT THEY WERE JUST DETERRED ENOUGH TO
STOP WORKING OUT AND STOP SUBSCRIBING TO MY APP. THAT
WAS A REALLY BAD PLACEMENT FOR THAT
AD FOR SURE.

I MOVE IT, AND I WAIT A WEEK.
I HOP BACK INTO THE SAME SCREEN IN THE NEW MACINTOSH. AND,
ADMOB. AND, WOW, EVERYTHING IS BACK AND UP TO THE RIGHT.
BUSINESS IS NOW BOOMING AT FITMOBBER, AND I AM A GLOBAL
COMPANY. I'M ALSO USING AN ADVANCED FEATURE CALLED
MEDIATION. AND MEDIATION IS VERY SIMPLE. IT'S BASICALLY A
SET OF RULES THAT ALLOW ME TO SEND MY AD UNITS TO DIFFERENT
AD NETWORKS.
AND IF YOU'RE A BIGGER APP PUBLISHER BUSINESS, THIS IS
REALLY IMPORTANT FOR YOU TO USE AND TO MAXIMIZE YOUR REVENUE.
MANAGING MEDIATION IN THE NEW ADMOB IS EASIER THAN EVER, WITH
A FEATURE CALLED MEDIATION GROUPS. AND WHAT MEDIATION
GROUPS LETS YOU DO IS IT LETS YOU SET UP A SINGLE SET OF
MEDIATION RULES AND THEN APPLY IT ACROSS APPS, AD UNITS, OR
GEOGRAPHIES. I'LL GIVE YOU AN EXAMPLE.
LET'S SAY THAT FITMOBBER IS DOING REALLY WELL, ESPECIALLY
IN JAPAN. AND IN JAPAN
ESPECIALLY, YOU WANT TO SEND YOUR ADS TO
DIFFERENT REGIONAL AD NETWORKS, BECAUSE THERE ARE A FEW AD
NETWORKS THERE THAT WANT TO BUY ADS JUST FOR USERS THERE.
USING MEDIATION GROUPS, IT'S NOW
VERY EASY TO DO THIS.

I SET UP ONE MEDIATION GROUP FOR JAPAN
WITH MY RULES. AND AFTER THAT, IT'S QUITE TRIVIAL TO ADD AD
UNITS. I CAN ADD AD UNITS TO THIS GROUP, AND IT WILL START
AUTOMATICALLY OBEYING THE RULES.
I CAN ALSO, IF I CHANGE MY MIND AND WANT TO REORDER OUR ADD
DIFFERENT — NEW AD NETWORKS, ADD THAT IN ONE PLACE OR CHANGE
IT IN ONE PLACE AND HAVE IT AUTOMATICALLY APPLY TO ALL OF
MY ADS IN MY JAPAN APP.
VERY SIMPLE AND VERY POWERFUL. AT THIS POINT, I'VE TALKED TO
YOU A LOT ABOUT HOW GOOGLE IS HELPING YOU BUILD A GREAT
IN-APP ADVERTISING BUSINESS.
I WANT TO PIVOT COMPLETELY AND TALK ABOUT ANOTHER EXTREMELY
CRUCIAL PART OF BUILDING A SUCCESSFUL BUSINESS, MAYBE THE
MOST CRUCIAL PART. AND THAT IS YOU CANNOT HAVE A SUCCESSFUL
MOBILE APPS BUSINESS WITHOUT HAVING A SUCCESSFUL GROWTH
STRATEGY.

AND IN ORDER TO DO THAT, YOU HAVE TO ANSWER TWO
QUESTIONS. NUMBER ONE IS, WHO ARE MY BEST USERS?
AND NUMBER TWO IS, WHERE CAN I FIND THEM? WHERE ARE THE MOST
EFFECTIVE CHANNELS THAT I CAN SHOW THEM MY APP AND GET THEM
TO DOWNLOAD AND TRY IT?
I'M EXCITED TO SHARE THAT GOOGLE
HAS BEEN WORKING ON THESE PROBLEMS. AND WE HAVE QUITE A
FEW FEATURES TO SHARE TO SOLVE THESE GROWTH CHALLENGES.
LET ME START WITH GOOGLE PLAY. ANDROID IS NOW ACTIVE WITH OVER
2 BILLION MONTHLY ACTIVE USERS EVERY MONTH. AND GOOGLE PLAY
IS IN OVER 190 COUNTRIES AROUND
THE WORLD. PEOPLE TURN TO GOOGLE
PLAY EVERY DAY TO DISCOVER GREAT
APPS AND GAMES TO ENJOY. AND WE
FIND INCREASINGLY, THAT BESIDES WHICH THEY DEFINITELY STILL DO,
THEY SEARCH FOR THE APPS THAT THEY WANT, THEY ARE ALSO
RESPONDING AND DOWNLOADING APPS THAT WE'RE RECOMMENDING TO THEM
AS THEY'RE BROWSING THE PLAY STORE.

TO HELP YOU FIND THOSE USERS
WHO ARE BROWSING AND DISCOVERING
THEIR NEXT FAVORITE APP IN THE PLAY STORE, WE ARE ANNOUNCING
NEW AD PLACEMENTS IN THE HOME AND APP LISTINGS PAGES OF THE
GOOGLE PLAY STORE.
THESE AD UNITS WILL ONLY BE AVAILABLE EXCLUSIVELY TO
UNIVERSAL APP CAMPAIGNS. AND THEY'LL HELP YOU REACH USERS
RIGHT WHEN THEY'RE IN THAT MODE OF DISCOVERY IN THE PLAY STORE.
OBVIOUSLY, BESIDES THE PLAY STORE, THERE ARE MANY OTHER
CHANNELS THAT PEOPLE ARE DISCOVERING THEIR NEXT FAVORITE
APP. AND THAT'S WHY WE BUILT UNIVERSAL APP CAMPAIGNS, OR
UAC, AS WE LIKE TO CALL IT. UAC
HELPS YOU REACH PEOPLE ACROSS MULTIPLE BILLION-USER
PROPERTIES, INCLUDING GOOGLE PLAY, GOOGLE SEARCH, YOUTUBE,
GMAIL, AND MILLIONS OF APPS AND WEB SITES ACROSS THE GOOGLE
DISPLAY NETWORK. IN ORDER TO USE UAC, IT'S VERY
EASY. YOU TELL US WHAT APP YOU WANT TO PROMOTE. YOU TELL US
THE PRICE THAT YOU WANT TO PAY PER INSTALL. AND YOU GIVE US A
LITTLE BIT OF INFORMATION TO HELP US CREATE ADS, LIKE TEXT,
IMAGES, VIDEOS. WE THEN TAKE ALL OF THAT
INFORMATION IN UAC, AND WE USE MACHINE LEARNING TO DELIVER THE
MAXIMUM NUMBER OF INSTALLS TO YOU AT THE PRICE THAT YOU'VE
SPECIFIED.

AND WE DO THIS BY AUTOMATING
AND OPTIMIZING EVERY SINGLE BIT OF
THE ADVERTISING ITSELF, INCLUDING WHAT THE ADS LOOK
LIKE, WHERE TO PUT THE ADS, AND ALSO, MORE IMPORTANTLY, WHAT TO
BID FOR EACH IMPRESSION AND CLICK SO THAT WE HIT THAT
TARGET PRICE THAT YOU WANT, WHILE
DELIVERING THE MAXIMUM NUMBER OF
INSTALLS FOR YOU. SO WHEREVER YOUR USERS ARE AND
WHATEVER THEY'RE DOING, WHETHER THEY'RE SEARCHING ON GOOGLE
OR WATCHING VIDEOS ON YOUTUBE,
ONLY GOOGLE HAS THE BREADTH OF
CHANNELS TO HELP YOU FIND YOUR MOST VALUABLE USERS RIGHT WHEN
THEY WANT TO DOWNLOAD YOUR APP. UNIVERSAL AD CAMPAIGNS HAS BEEN
HELPING COMPANIES LIKE HEAD SPACE, WHICH IS A VERY POPULAR
MEDITATION APP, IMPROVE HEALTH AND HAPPINESS AROUND THE WORLD. AND ACCORDING TO ROBERT FROM
HEAD SPACE, UNIVERSAL APP CAMPAIGNS HAS SAVED THEIR TEAM
TIME AND DRIVEN RESULTS.

TRANSLATION: MORE USERS THAT
USE AND LOVE THE APP IN LESS TIME.
HOWEVER, LIKE HEADSPACE, WE ALL KNOW THAT GROWTH ISN'T JUST
ABOUT INSTALLS. MANY USERS WILL
INSTALL YOUR APP AND NOT GO ALONG AND SPEND OR ENGAGE OR
POTENTIALLY EVEN OPEN IT. YOU NEED TO SPEND YOUR ACQUISITION
DOLLARS WISELY TO FIND YOUR MOST
VALUABLE USERS, THE ONES THAT WILL ENGAGE AND SPEND AND
ACTIVATE AND ENJOY YOUR APPS. BECAUSE OF THAT, I'M ALSO
EXTREMELY HAPPY THAT WE'RE ANNOUNCING TWO NEW BIDDING
OPTIONS IN UNIVERSAL APP CAMPAIGNS, TARGET CPA, OR COST
PER ACQUISITION, AND TARGET ROAS, OR RETURN ON AD SPEND.
AND THESE BIDDING STRATEGIES WILL HELP YOU PROFITABLY
ACQUIRE HIGH-VALUE USERS.

OR PUT MORE
SIMPLY, HELPS YOU PAY MORE FOR USERS WHO WILL PAY YOU MORE AND
PAY LESS FOR USERS WHO WE THINK WILL PAY YOU SO I GIVE YOU A
VERY CONCRETE EXAMPLE. MY HUSBAND
AND I LESS ARE BOTH MOBILE GAMERS,
AND WE BOTH LOVE THIS NEW GAME BY NINTENDO CALLED FIRE
EMBLEM HEROES. I DON'T KNOW IF YOU PLAYED IT OR NOT.
IT'S TACTICAL RP TPUS AND BASICALLY IN THIS GAME YOU
COLLECT HEROES AND THE WAY YOU COLLECT HEROES IS THROUGH
EXCHANGING A VIRTUAL CURRENCY CALLED ORBS. NOW, I'M SURE
MOST OF YOU WHO PLAY GAMES KNOW THE WAY TO GET ORBS IS
BASICALLY TWO WAYS. ONE IS YOU BUY THEM WITH REAL MONEY,
AND NUMBER TWO IS YOU CAN SORT OF GRIND IT OUT IN THE
GAME AND EARN THEM OVER THE COURSE OF PLAYING.
NOW, I AM REALLY VERY IMPATIENT AND ALSO VERY
COMPETITIVE, SO I HAVE NO ISSUES SPENDING OVER A
HUNDRED DOLLARS BUYING ORBS TO COLLECT MY FAVORITE
HEROES.

MY HUSBAND, ON THE OTHER
HAND, IS MORE PRINCIPLED AND WANTS TO GRIND IT OUT, AND
HE'S JUST A LITTLE CHEAP, SO HE'S WILLING TO SPEND MAYBE,
AT MOST, $5. FOR AN APP DEVELOPER LIKE
NINTENDO, THEY SHOULD BE THINKING ABOUT ACQUIRING
PLAYERS LIKE ME AT THE HIGH PRICE POINT, AT A HIGHER
PRICE POINT THAN PLAYERS LIKE MY HUSBAND WHO SPEND A LOWER
PRICE POINT. AND WITH THESE NEW BIDDING STRATEGIES, THEY
CAN DO EXACTLY THAT. AND FINALLY, AT THE CORE OF
ANY SMART GROWTH STRATEGY IS MEASURING WHETHER YOU'RE
SPENDING YOUR ACQUISITION DOLLARS WISELY. AND WHEN WE
KNOW THAT MANY OF YOU ARE USING THIRD-PARTY MEASUREMENT
PROVIDERS TO MEASURE THE ATTRIBUTION OF YOUR INSTALLS.
AND THAT'S WHY TODAY I'M HAPPY TO ANNOUNCE THAT GOOGLE
IS LAUNCHING A COMPLETELY NEW APP ATTRIBUTION PROGRAM.

AND
WHAT THIS PROGRAM DOES IS IT'S DESIGNED TO INTEGRATE
DATA FROM THESE SEVEN GLOBAL COMPANIES THAT YOU SEE ON
THIS SLIDE RIGHT INTO ADWORDS. AND OUR GOAL IS TO
CREATE CONSISTENCY AND RELIABILITY OF THE DATA
INTEGRATION AND THE RESULTS THAT YOU'LL GET.
WE HAVE ALSO STREAMLINED THE FLOW, SO IT'S INCREDIBLY EASY
NOW TO GET THESE APP MEASUREMENT COMPANIES UP AND
RUNNING IF YOU'RE USING ADWORDS.
WITH THAT, I WANT TO THANK YOU ALL FOR THE OPPORTUNITY
TO BE HERE AND SHARE ALL OF THESE GREAT FEATURES THAT MY
TEAM HAS BEEN WORKING ON.

PLEASE TRY THEM OUT AND
PLEASE SHARE YOUR FEEDBACK WITH US.
AND WITH THAT, I'D LIKE TO TURN IT BACK TO SRIDHAR TO
CLOSE WITH HIS FINAL THOUGHTS.
THANK YOU. [ APPLAUSE ]
Sridhar Ramaswamy: THANK YOU, SISSIE.
YOU KNOW, IT'S REALLY EXCITING ABOUT PRESENTING TO
YOU ALL OF YOU? WE KNOW THAT WE HAVE THE MOST INNOVATIVE
THINKERS IN THE APP WORLD RIGHT HERE. WE KNOW THAT
MANY OF THE PRODUCTS THAT REDEFINE HOW WE COMMUNICATE,
SHOP, STAY ENTERTAINED, ARE GOING TO BE DONE BY YOU.
THAT'S WHY WE FIND IT SO EXCITING.
AND WE ALSO KNOW THAT IN ORDER TO TURN THESE PRODUCTS
INTO SUCCESSFUL BUSINESSES, IT'S MORE IMPORTANT THAN EVER
BEFORE FOR YOU TO FIGURE OUT HOW TO SIMPLIFY THE PAYMENTS
PROCESS, HOW TO TAILOR YOUR AD EXPERIENCES TO GENERATE
THE MAXIMUM AMOUNT OF REVENUE, AND TO FIND THE
RIGHT USERS FOR YOUR APP. AND THOSE OF YOU THAT DO THIS
ARE REALLY THE ONES THAT ARE GOING TO BE SUCCESSFUL.
WE HAVE A NUMBER OF GREAT FOLLOW-UP SESSIONS, INCLUDING
ONE ON PAYMENTS RIGHT AFTER THIS. THEY'RE UP HERE.
THANK YOU ALL FOR LISTENING TO US.
TAKE CARE.

– – – – HE Rahul Roy-Chowdhury: HELLO,
EVERYONE! [ APPLAUSE ]
MY NAME IS RAHUL, I'M THE PRODUCT LEAD ON CHROME, AND
I'M EXCITED TO BE BACK UP HERE AGAIN THIS YEAR TO TELL
YOU ABOUT ALL THE AMAZING PROGRESS WE'VE MADE OVER THE
LAST 12 MONTHS. THE THEME OF TODAY, AND
SOMETHING YOU'RE GOING TO HEAR AGAIN AND AGAIN, IS THAT
THE MODERN MOBILE WEB IS NOW MAINSTREAM. AND THIS IS
REALLY AN AM AMAZING SHIFT. SO I'M GOING TO TELL YOU ALL
ABOUT WHAT HAS BEEN HAPPENING AND WHAT IT MEANS FOR YOU.
IT'S THE MOBILE WEB STATE OF THE UNION. SO LET'S DIVE
RIGHT IN.
THE WEB HAS INCREDIBLE REACH. JUST CHROME ALONE RUNS ON
OVER 2 BILLION DEVICES FROM PHONES TO TABLETS TO PCs.

AND THE WEB IS MUCH BIGGER THAN CHROME. THERE ARE OVER
5 BILLION DEVICES OUT THERE THAT CAN ACCESS WEB CONTENT.
5 BILLION! THAT IS A LARGE NUMBER. AND THIS DIDN'T
HAPPEN BECAUSE OF LUCK. THIS WIDE REACH IS A DIRECT
CONSEQUENCE OF HOW THE WEB OPERATES. IT IS AN OPEN,
DECENTRALIZED PLATFORM. IT HAS NO GATEKEEPERS.
DEVELOPERS GET WIDE REACH. USERS GET LOW FRICTION.
AND ON THE CHROME TEAM, OUR MISSION HAS ALWAYS BEEN TO
MOVE THE WEB PLATFORM FORWARD. WE SPEND A LOT OF
TIME WORKING ON MAKING THE WEB PLATFORM BETTER. LOTS OF
THINGS ON THE FOUNDATIONS. THINGS THAT JUST HAPPEN UNDER
THE HOOD THAT YOU MAY NOT EVEN RECOGNIZE, BUT AT EVERY
SEARCH CHANGE, THE WEB PLATFORM JUST GETS BETTER.
TO TAKE ONE EXAMPLE, OVER THE LAST YEAR, WE FOCUSED OUR
JAVASCRIPT PERFORMANCE ON REAL-WORLD WEB USAGE.

IT'S
SORT OF LIKE WHAT KIND OF CAR WOULD YOU RATHER DRIVE? A
CAR THAT'S BEEN ROAD TESTED IN REAL-WORLD DRIVING
CONDITIONS OR A CAR THAT'S BEEN TESTED IN AN ARTIFICIAL
LAB SETTING? WE WANT OUR CAR, AND OUR
JAVASCRIPT ENGINE IS LITERALLY CALLED V8, WE WANT
OUR CAR TO BE GREAT ON THE ROADS THAT PEOPLE ACTUALLY
DRIVE ON. AND CURRENTLY WE THINK THE SPEEDOMETER
BENCHMARK BEST CAPTURES THIS REAL-WORLD USAGE SO I'M
PLEASED TO ANNOUNCE THAT CHROME ON ANDROID IS NOW 35%
FASTER ON THE SPEEDOMETER BLARK COMPARED TO A
BENCHMARK COMPARED TO A YEAR AGO.
[ APPLAUSE ] AND WE'VE SEEN SIMILAR GAINS
ON OTHER OS'S AS WELL. TO TAKE ANOTHER EXAMPLE, I'M
SURE ALL OF US HAVE EXPERIENCED THE ANNOYANCE OF
LOADING A WEB PAGE AND STARTING TO READ SOME CONTENT
ONLY TO HAVE IT JUMP TO A DIFFERENT LOCATION.

AND THIS
USUALLY HAPPENS BECAUSE SOME OFF-SCREEN CONTENT IS LOADED
IN AND PUSHED DOWN THE VISIBLE CONTENT.
NOW, TO IMPROVE THIS USER EXPERIENCE, WE LAUNCHED A NEW
FEATURE CALLED SCROLL ANCHORING. AND SCROLL
ANCHORING WORKS BY LOCKING THE SCROLL POSITION TO AN
ELEMENT THAT IS VISIBLE ON THE PAGE, SO THE USER SAYS IN
THE SAME POSITION EVEN AS OUR SCREEN CONTENT GETS LOADED
IN. SO TO SHOW YOU WHAT IT LOOKS
LIKE IN ACTION, ON THE LEFT IS CHROME WITHOUT SCROLL
ANCHORING, AND ON THE RIGHT IS CHROME WITH SCROLL
ANCHORING ENABLED. AND THIS IS A LONG PAGE, AND AS WE
SCROLL DOWN TO THE BOTTOM OF THIS PAGE, YOU'LL SEE ON THE
RIGHT THE PAGE STAYS LOCKED IN POSITION WHILE ON THE LEFT
THE PAGE IS JUMPING ALL OVER THE PLACE AS OUR SCREEN
CONTENT GETS LOADED IN.

NOW, THIS IS A BIT OF A
CONTRIVED DEMO JUST TO SHOW YOU EXACTLY WHAT'S GOING ON.
BUT SINCE WE LAUNCHED THIS FEATURE, WHAT WE HAVE SEEN IS
THAT ON AVERAGE, SCROLL ANCHORING PREVENTS THREE
JUMPS PER PAGE LOAD. SO THIS HAS HAD A HUGE IMPACT ON THE
QUALITY OF THE USER EXPERIENCE.
AND THERE ARE MANY MORE SUCH CHANGES. THINGS THAT DON'T
NEED ANY ACTION FROM DEVELOPERS OR USERS BUT THAT
JUST MAKE THE WEB PLATFORM BETTER.
SO THAT'S THE FOUNDATION. NEXT COME ALL OF THE FEATURES
AND APIs THAT ENABLE YOU ALL TO DO GREAT THINGS, TO
BUILD GREAT EXPERIENCES ON TOP OF THAT FOUNDATION.

AND
TODAY I'M GOING TO TALK ABOUT THE AMAZING MOMENTUM WE'VE
SEEN ACROSS THE CORE PILLARS OF THE MODERN MOBILE WEB.
I'M GOING TO TALK ABOUT WHAT WE ARE DOING TO MAKE WEB APPS
MORE POLISHED AND FEEL FOR INTEGRATED INTO THE DEVICE,
AND I'M GOING TO TALK ABOUT ALL THE WAYS WE'RE WORKING ON
TO MAKE BUILDING WEB APPS EASIER THAN EVER BEFORE.
SO LET'S START WITH MOMENTUM. ONE OF THE CORE PILLARS OF
THE MODERN MOBILE WEB IS ACCELERATED MOBILE PAGES OR
AMP FOR CONTENT-FOCUSED EXPERIENCES. NOW, WE ALL
KNOW THAT CONTENT EXPERIENCES ON THE WEB CAN SOMETIMES BE
QUITE PAINFUL, AND WE SPEARHEADED THE AMP PROJECT
LAST YEAR, THE OPEN SOURCE AMP PROJECT LAST YEAR, TO
IMPROVE THIS EXPERIENCE. AND THE BENEFITS THAT AMP
BRINGS ARE STARK. ON AVERAGE, AN AMP PAGE LOADS IN
LESS THAN A SECOND, AND IT USES TEN TIMES LESS DATA.
AND AS A RESULT, THE GROWTH OF AMP HAS BEEN PHENOMENAL.
LAST YEAR AT THIS TIME, THERE WERE 125 MILLION AMP
DOCUMENTS OUT THERE, AND TODAY THERE ARE OVER 2
BILLION AMP PAGES FROM OVER 900,000 DIFFERENT DOMAINS.
[ APPLAUSE ] AMAZING MOMENTUM
MANY AND MORE AND MORE PLATFORMS ARE NOW LINKING OUT
TO AMPs.

AND THEY'RE DOING THIS BECAUSE THEY FIND THAT
USERS ARE MORE ENGAGED WHEN THEY CAN GET TO THE CONTENT
FASTER. FOR EXAMPLE, LINKEDIN HAS
FOUND THAT PEOPLE SPEND 10% MORE TIME READING AN ARTICLE
WHEN IT'S AN AMP PAGE VERSUS WHEN IT'S NOT.
AND TODAY I'M EXCITED TO ANNOUNCE THAT SEVERAL NEW
PARTNERS ARE GOING TO BE SUPPORTING THE AMP PROJECT IN
THE COMING WEEKS. TWITTER WILL BEGIN LINKING OUT TO
AMPs ACROSS ALL OF THEIR MOBILE WEB AND NATIVE APP
PROPERTIES. TUMBLR WILL BEGIN USING AMP FOR THEIR
BLOGS. WE GOA AND QZONE HAD
ALSO BEGIN LINKING OUT TO AMP AS WELL.

AND FINALLY AMP IS
SEEING SUCCESS IN NEW VERTICALS LIKE eCOMMERCE
WITH COMPONENTS SUCH AS AMP-BIND YOU CAN BUILD
ENGAGING EXPERIENCES AND MANY MERCHANTS ARE DOING JUST
THAT. SO THAT'S AMP, A GREAT WAY TO
BUILD CONTENT-FOCUSED EXPERIENCES FOR THE MODERN
MOBILE WEB. THE SECOND PILLAR OF THE
MODERN MOBILE WEB IS PROGRESSIVE WEB APPS OR
PWAs. PROGRESSIVE WEB APPS ARE A WAY TO BUILD AP-FOCUSED
EXPERIENCES THAT ARE RELIABLE, FAST, AND ENGAGING.
AND WE WERE INSPIRED TO START THIS JOURNEY BASED ON OUR
BELIEF THAT WEB EXPERIENCES CAN AND SHOULD BE RADICALLY
BETTER. AND USERS LOVE THESE
EXPERIENCES, WHICH MEANS THAT THEY'RE MORE ENGAGED, WHICH
MEANS CONVERSIONS ARE HIGHER, WHICH MEANS BUSINESS METRICS
ARE BETTER. SO THIS IS JUST A GOOD THING ALL AROUND.
BUT RATHER THAN ME TELL YOU ABOUT HOW AWESOME OUR
PROGRESSIVE WEB APPS ARE, LET'S TAKE A LOOK AT ONE THAT
JUST LAUNCHED RECENTLY.

IT'S MY PLEASURE TO INVITE UP ON
STAGE PATRICK TRAUGHBER AND KATIE SIEVERT FROM TWITTER.
[ APPLAUSE ] Patrick Traughber: THANK
YOU, RAHUL. HELLO, GOOGLE I/O. MY NAME
IS PATRICK TRAUGHBER, AND I'M THE PRODUCT MANAGER FOR
TWITTER LITE. Katie Sievert: AND I'M KATIE
SIEVERT, ENGINEER ON THE TWITTER LITE TEAM.
Patrick Traughber: JUST FIVE WEEKS AGO WE LAUNCHED TWITTER
LITE FOR THE GOAL OF DELIVERING A GREAT USER
EXPERIENCE AT SCALE.
SORRY. SORRY. ONE SECOND. WE SET OUT TO BUILD THE
TWITTER CLIENT THAT, ONE, LOADS QUICKLY ON SLOW
NETWORKS; TWO, USES LESS MOBILE DATA; AND, THREE,
WORKS ON ALL SMARTPHONES.
EACH MONTH, MORE THAN 300 MILLION USERS COME TO TWITTER
TO FIND OUT WHAT'S HAPPENING IN THE WORLD, AND OVER 80% OF
OUR USERS ARE ON MOBILE DEVICES.
WE WERE SEEING HEALTHY GROWTH IN MOBILE WEB USAGE AT
TWITTER SO WE WANTED TO MAKE SURE THAT THIS EXPERIENCE WAS
TOP NOTCH.

BUT RATHER THAN JUST TELLING
YOU ABOUT TWITTER LITE, WHY DON'T WE GIVE YOU A LIVE
DEMO. KATIE, CAN YOU WALK US
THROUGH TWITTER LITE? Katie Sievert: SURE.
LET'S PULL IT UP. WHEN USERS VISIT TWITTER LITE
ON ANDROID, THEY'RE PROMPTED TO ADD IT TO THEIR HOME
SCREEN. IN FACT, TWITTER LITE RECEIVES A MILLION
VISITS EACH DAY VIA THE HOME SCREEN ICON.
LET'S GO AHEAD AND LAUNCH IT. AS YOU CAN SEE, IT INITIALLY
LAUNCHES US IN FULL-SCREEN MODE JUST LIKE A NATIVE APP,
AND TWITTER LIGHT IS OPTIMIZED FOR SPEED TAKING
ADVANTAGE OF THE PRPL, AND IT
CONSUMES NO ADDITIONAL DATA. AS YOU SCROLL THROUGH THE
TIMELINE IT'S FAST AND SMOOTH LIKE A NATIVE APP, AND SINCE
MANY PEOPLE COME TO TWITTER TO GET THE LATEST NEWS AND
TAP ON PUBLISHING LINKS WE HAVE BEEN BIG FANS OF AMP.

LET'S SEE WHAT OWEN IS TWEETING. HE USUALLY TWEETS
INTERESTING ARTICLES. LET'S CHECK OUT THIS ONE.
Patrick Traughber: WE'RE EXCITED TODAY TO ANNOUNCE
THAT TWITTER LITE LINKS — NOW LINKS OUT TO AMP PAGES SO
THAT CONTENT LOADS ALMOST INSTANDPOINTLY AND USES LESS
MOBILE DATA. [ APPLAUSE ]
FOR EXAMPLE, YOU CAN SEE HERE THAT WHEN KATIE TAPPED THE
LINK TO THE GUARDIAN POST ON OWEN'S PROFILE PAGE, IT
LOADED INSTANTLY IN A NEW TAB.
Katie Sievert: NOW LET'S SHOW OFF A COUPLE OF
ENGAGEMENT FEATURES.

ONE OF THE KEY PIECES OF A POLISHED
EXPERIENCE IS MAKING SURE USERS CAN CAPTURE MEDIA AND
TWEET IT. SO TO MAKE THINGS A LITTLE
MORE INTERESTING SLASH EXCITING, WHAT DO YOU SAY
ABOUT DOING A LIVE PHOTO TWEET FROM ON STAGE?
[ CHEERS ] ALL RIGHT. IT'S LIKE YOU
KNEW I WAS ALREADY GOING DO IT ANYWAY.
ALL RIGHT. WITH A DISCLAIMER THAT I'M NOT A PROFESSIONAL
PHOTOGRAPHER, ALTHOUGH YOU DON'T NEED TO TO USE TWITTER.
EVERYONE STRIKE A POSE. [ CHEERING ]
Katie Sievert: ALL RIGHT. CENTER THAT. SO LET'S TYPE, "TWITTER LITE LIVE DEMO AT
HASHTAG IO17" TWEET.
AH, SUCCESS. SO WE SEE THE TWEET RIGHT THERE. NOW HALF
OF THE FUN IS RECEIVING RETWEETS —
[ APPLAUSE ] OH, THANK YOU. YES.
SUCCESSFUL DEMOS ARE ALL APPLAUSE WORTHY.
HALF THE FUN IS SEEING THAT LITE RETWEETED SOMETHING
AFTER YOU TWEETED SOMETHING AND ONE IMPACT HAS HAD A HUGE
IMPACT ON THIS IS PUSH NOTIFICATIONS.

SO LET'S PULL
UP AN ENTIRELY NOT CANNED TWEET. SO MARIUS HAS DONE A
RETWEET. CLICK ON IT, CLICK ON THAT TWEET. NOTIFYING
USERS ABOUT ACTIVITY IS KEY TO BRINGING THEM BACK IN THE
APP AND THIS IS IMPORTANT FOR US AND SINCE RECENTLY ADDING
IT WE HAVE BEEN SENDING MORE THAN 10 MILLION PUSH WOITION
WOITION NOTIFICATIONS A DAY. BUT I CAN KEEP GOING FOR A
PRETTY LONG TIME BUT IN THE INTEREST OF TIME AND KEEPING
THINGS LIGHT, LET'S SEND IT BACK TO PATRICK.
Patrick Traughber: THANK YOU, KATIE.
[ APPLAUSE ] IT WAS IMPORTANT FOR US TO
DELIVER A FAST, ENGAGING EXPERIENCE WHILE CONSUMING
LESS MOBILE DATA.

TWITTER LITE ALREADY CONSUMES LESS
DATA AS COMPARED TO OUR NATIVE APPS, BUT ON TOP OF
THAT WE LAUNCHED A NEW FEATURE CALLED DATA SAVER.
WHEN A USER IS IN DATA SAVER MODE THEY CAN SAVE UP TO AN
ADDITIONAL 70% ON THEIR DATA. EVERYONE.
NOW, TWITTER LITE DELIVERS ALL OF THE KEY FEATURES AT A
FRACTION OF THE SIZE COMPARED TO OUR NATIVE APPS. HERE YOU
CAN SEE THE SIZE DIFFERENCE OF TWITTER LITE COMPARED TO
OUR ANDROID AND iOS APPS. AND OF COURSE THE MOBILE WEB
IS MORE THAN JUST A LANDING PAGE. WE'RE EXCITED TO
PROVIDE A FAST, FEATURE-RICH EXPERIENCE AND OUR USERS FROM
AROUND THE WORLD, FROM NIGERIA TO JAPAN TO ECUADOR,
THE PHILIPPINES, THEY LOVE IT AS WELL.
AND WE SEE IT IN OUR METRICS, TOO.

WE'RE SEEING INCREASES
IN PAGES-PER-SESSION AND TWEETS SENT FROM TWITTER
LITE. AND LIKE KATIE SAID, WE'RE SEEING MORE THAN 1
MILLION LAUNCHES FROM THE HOME SCREEN EVERY DAY.
MOST IMPORTANTLY, OUR USERS ARE HAPPY. TWITTER LITE IS
OUR NEW, STANDARD MOBILE WEB EXPERIENCE, AVAILABLE TO ALL
USERS GLOBALLY ON ANDROID AND iOS, AND WE HOPE YOU
CHECK IT OUT. THANK YOU. [ APPLAUSE ] Rahul Roy-Chowdhury: GREAT.
THANK YOU, PATRICK AND KATIE. TWITTER.COM IS A PWA, FOLKS.
THE MODERN MOBILE WEB IS TRULY MAINSTREAM. AND IT'S NOT JUST
TWITTER. LAST YEAR WE TALKED ABOUT SOME EARLY ADOPTERS OF
PROGRESSIVE WEB APPS. AND SINCE
THEN THE MOMENTUM AND GROWTH HAS
BEEN PHENOMENAL. THESE LAUNCHES
ARE HAPPENING ALL OVER THE WORLD
AND THEY'RE HAPPENING ACROSS ALL
INDUSTRY SEGMENTS. LARGE TRAVEL COMPANIES, LIKE
EXPEDIA AND TRIVAGO AND WEGO HAVE ALL LAUNCHED PROGRESSIVE
WEB APPS. PUBLISHERS LIKE INFOBAE AND FORBES HAVE
LAUNCHED PROGRESSIVE WEB APPS.

FORBES
HAS SEEN THEIR USER ENGAGEMENT DOUBLE SINCE THE LAUNCH OF
THEIR PROGRESSIVE WEB APP.
eCOMMERCE SITES LIKE FANDANGO, RAKATAN AND ALIBABA ARE ALL
INVESTING IN PWAs. AND EVEN NEW SERVICES THAT WE TEND TO
THINK OF AS APP-ONLY LIKE RIGHT SHARING SERVICES HAVE GOTTEN IN
ON THE ACTION. LYFT LAUNCHED THEIR PROGRESSIVE
WEB APP LAST FALL AND OLA CABS, INDIA'S LARGEST RIDE SHARING
SERVICE JUST RECENTLY LAUNCHED THEIR PWA. AND, IN FACT, OLA
WILL BE UP ON STAGE IN JUST A BIT TO SHOW IT OFF TO YOU.
NOW, ONE REASON PROGRESSIVE WEB APPS IS SO SUCCESSFUL IS THAT
MULTIPLE BROWSERS ARE COMMITTED TO THEM.

SO WHILE DEVELOPER
ADOPTION IS GROWING, SO IS BROWSER SUPPORT. AND IF A
BROWSER YOU CARE ABOUT ISN'T ON THIS LIST YET , PROGRESSIVE WEB
APPS ARE DESIGNED TO WORK WELL EVERYWHERE. SO YOU CAN ALWAYS
COUNT ON REACHING THE USERS THAT
ARE IMPORTANT TO YOU. TAKE THE EXAMPLE OF LUXURY COSMETICS
BRAND LANCOME. LANCOME RECENTLY
LAUNCHED A PROGRESSIVE WEB APP AND IT WORKS GREAT ON ALL
BROWSERS AND THEY HAVE SEEN GREAT STATS. BUT WHAT I WANT
TO CALL OUT HERE IS THAT iOS IS
PARTICULAR IMPORTANT FOR LANCOME
BECAUSE 65% OF THEIR MOBILE WEB USERS ARE ON iPHONES. AND
WHAT LANCOME OBSERVED WAS THAT THOSE iOS USERS HAVE A SESSION
LENGTH THAT IS NOW 53% HIGHER THAN IT WAS BEFORE THEIR
LAUNCH. AND THIS IS DESPITE THE FACT
THAT SOME PWA FEATURES ARE NOT SUPPORTED ON THAT PLATFORM.
NOW, THE PROGRESSIVE IN
PROGRESSIVE WEB APPS REALLY REFERS TO PROGRESSIVE
ENHANCEMENT. BUT WHAT IT REALLY
MEANS IS YOU CAN COUNT ON REACHING THE USERS THAT ARE
IMPORTANT TO YOU NO MATTER WHAT BROWSER MIX YOU CARE ABOUT.
SO THE MOMENTUM AND GROWTH ACROSS THE CORE PILLARS OF THE
MODERN MOBILE WEB, ACROSS AMP AND PROGRESSIVE WEB APPS HAS
BEEN TRULY INCREDIBLE OVER THE LAST 12 MONTHS.
THE MODERN MOBILE WEB IS NOW TRULY MAINSTREAM.

NOW, WHILE
ALL OF THIS MOMENTUM IS HAPPENING ALL AROUND US, WE
HAVE BEEN HEADS DOWN WORKING ON
MAKING PROGRESSIVE WEB APPS EVEN
BETTER. OUR GOAL IS TO MAKE WEB APPS
FEEL MORE INTEGRATED INTO THE OVERALL DEVICE SO USERS GET A
ROBUST NO-COMPROMISES EXPERIENCE.
HOW ARE WE DOING THIS? WE'RE ADDING A LOT OF NEW APIs TO
THE WEB PLATFORM. IN FACT, WE ADDED 215 NEW APIs JUST SINCE
GOOGLE I/O LAST YEAR. BUT WHAT'S REALLY IMPORTANT IS
NOT THE NUMBER OF APIs WE SHIP. WHAT'S REALLY IMPORTANT
IS WHAT USE CASES CAN THESE APIs UNLOCK FOR YOU. AND I
WANT TO TALK ABOUT THREE USE CASES TODAY.
INSTALLING WEB APPS TO YOUR DEVICE, PAYING FOR THINGS ON
THE WEB, AND POLISHED MEDIA
EXPERIENCES. LET'S START WITH
INSTALLABILITY. WE ALREADY HAVE A WAY TO ADD
WEB APPS TO YOUR HOME SCREEN. BUT
WE'VE MADE IT A LOT BETTER. NOW, FIRST OF ALL, WE'VE HEARD
FROM MANY OF YOU THAT YOU WOULD LIKE THE INSTALL PROMPT TO BE
MORE RELIABLE AND PREDICTABLE. AND WE'VE HEARD YOUR FEEDBACK
LOUD AND CLEAR. SO I'M HAPPY TO
REPORT THAT NOW YOU CAN SHOW THE
INSTALL PROMPT TO YOUR USERS WHEN YOU WANT.
[ APPLAUSE ]
AND ONCE A USER HAS INSTALLED YOUR WEB APP TO THEIR DEVICE,
IT SHOWS UP EVERYWHERE YOU EXPECT
AN APP TO SHOW UP.

THEY SHOW UP
IN THE APP LAUNCHER, NOT JUST THE HOME SCREEN.
[ APPLAUSE ] THEY'RE INTEGRATED INTO ANDROID
SETTINGS. THEY PARTICIPATE IN
THE ANDROID INTENTS SYSTEM LIKE ALONGSIDE ANY OTHER NATIVE APP. THEY CAN HANDLE NOTIFICATIONS
NATIVELY RATHER THAN THROUGH CHROME. AND WEB APPS CAN LAUNCH
IN FULL-SCREEN MODE JUST LIKE ANY NATIVE ANDROID APP CAN AS
WELL. SO IT'S EASIER THAN EVER BEFORE
TO INSTALL WEB APPLICATIONS TO YOUR DEVICE. SO FROM
INSTALLING WEB APPS TO YOUR DEVICE, LET'S
LOOK AT OUR SECOND USE CASE: PAYING FOR THINGS ON THE WEB.
MOBILE PAYMENTS ARE A BIG DEAL. $123 BILLION LAST YEAR JUST IN
THE U.S. ALONE. AND TO MAKE PAYMENT FLOWS ON THE WEB
BETTER, WE LAUNCHED A ONE-TAP PAYMENTS
API CALLED PAYMENT REQUEST. AND IT WORKS WITH CREDIT CARDS,
AND IT WORKS WITH GOOGLE FORMS OF PAYMENT SUCH AS ANDROID PAY.
AND MANY MERCHANTS ARE ACTIVELY USING THIS API TODAY, BUT WE
KNOW THAT CREDIT CARDS ARE JUST PART OF THE PUZZLE HERE.

PEOPLE HAVE LOTS OF DIFFERENT WAYS TO
PAY FOR THINGS, AND WE WANT TO MAKE SURE THAT A USER ON THE
WEB CAN PAY FOR THINGS USING THE
PAYMENT APPS THEY ALREADY USE. SO I'M VERY PLEASED TO ANNOUNCE
THAT NOW YOUR WEB SITE CAN INTEGRATE WITH ANY SUPPORTED
PAYMENT APP USING PAYMENT REQUEST. SO IF A USER HAS A
NATIVE PAYMENT APP INSTALLED, YOU CAN INTEGRATE THAT RIGHT
INTO YOUR PAYMENT PLOW ON THE WEB — FLOW ON THE WEB. WE ARE
ALREADY WORKING WITH SAMSUNG PAY
AND ALIPAY AND MANY OTHER NATIVE
PAYMENT APPS WILL BE INTEGRATED VERY SOON. IT'S NOT JUST
NATIVE PAYMENT APPS, WE WANT WEB APPS
TO BE INTEGRATED AS WELL. WE ARE ACTIVELY PARTNERING WITH
PAYPAL TO BRING THEIR WEB APP RIGHT INTO PAYMENT REQUEST.
SO WE WANT TO MAKE SURE THAT THE
ENTIRE THIRD-PARTY PAYMENT ECOSYSTEM IS AVAILABLE FOR YOU
IN YOUR CHECKOUT FLOW ON THE WEB.
SO FROM INSTALLING WEB APPS TO YOUR DEVICE AND PAYMENTS, LET'S
LOOK AT OUR THIRD USE CASE: MEDIA EXPERIENCES.
MEDIA IS IMPORTANT.

OVER 70% OF
INTERNET TRAFFIC IS VIDEO, AND SO IT'S IMPORTANT TO US THAT WE
DELIVER A COMPLETE SOLUTION FOR MEDIA ON THE MOBILE WEB.
NOW, WE'VE BEEN WORKING ON ADDING MANY NEW APIs, THINGS
LIKE THE MEDIA SESSIONS API, BACKGROUND FETCH, FULL SCREEN
ORIENTATION AND MANY OTHERS. AND WE PUT TOGETHER A SAMPLE
APP TO SHOW YOU THE KIND OF MEDIA
EXPERIENCES THAT ARE POSSIBLE USING THESE APIs. AND SO LET
ME WALK YOU THROUGH SOME OF THE HIGHLIGHTS.
FIRST, AS YOU CAN SEE, I HAVE INSTALLED THE APP TO MY DEVICE. AND WHEN I TAP ON IT, IT
LAUNCHES IN FULL-SCREEN MODE WITH A SPLASH SCREEN. AND APP
BRANDING IS FRONT AND CENTER. THERE'S NO CHROME UI ANYWHERE
HERE. AND WHEN I TAP ON A VIDEO
TO PLAY IT — OH, ACTUALLY, WHEN
I SCROLL UP AND DOWN, YOU CAN SEE THAT THE APP FEELS SMOOTH
AND FLUID AND JUST WORKS REALLY — JUST WORKS IN A VERY
POLISHED WAY.

AND WHEN I TAP ON A VIDEO TO
PLAY IT, IT PLAYS BACK INSTANTLY. AND THIS IS NOT
BECAUSE THE WiFi IS REALLY GOOD. IT'S BECAUSE WE PREFETCH
THE FIRST FEW SECONDS OF VIDEO SO THAT WE CAN ENABLE INSTANT
PLAYBACK. AND IF I JUST FLIP MY PHONE
OVER, IT WILL INSTANTLY ENTER FULL-SCREEN MODE, AND YOU CAN
SEE THIS VIDEO HAS CUSTOM CONTROLS, SO I CAN GO BACKWARDS
AND FORWARDS 30 SECONDS. AND AS
I USE THE SCROLL BAR, YOU SEE THUMBNAILS START TO APPEAR.
AND IF I LOCK THE DEVICE, YOU CAN SEE THE BACKGROUND POSTER
IMAGE AND YOU CAN SEE MEDIA CONTROLS APPEAR RIGHT ON THE
LOCK SCREEN. AND THIS COULD BE REALLY USEFUL, FOR EXAMPLE, IF
I'M LISTENING TO AUDIO ON MY MORNING COMMUTE. AND, FINALLY, THIS ALL WORKS
REALLY WELL OFFLINE AS WELL. SO
IF I GO INTO AIRPLANE MODE, I CAN VIEW VIDEOS THAT I HAVE
PREVIOUSLY SAVED FOR OFF-LINE VIEWING AND I CAN TAP ON IT AND
I CAN PLAY THE VIDEO WHILE I'M OFF LINE.
ALL OF THIS GOODNESS IS AVAILABLE ON THE MOBILE WEB
TODAY.

SO FROM INSTALLING WEB APPS TO YOUR DEVICE, TO PAYING
FOR THINGS ON THE WEB, TO POLISHED MEDIA EXPERIENCES,
WE'RE WORKING HARD TO MAKE USING
WEB APPS A GREAT EXPERIENCE. WE'RE ALSO WORKING HARD TO MAKE
BUILDING WEB APPS A GREAT EXPERIENCE. SO HERE'S A
QUESTION. HOW GOOD IS YOUR CURRENT WEB APP? AND HOW DO
YOU EVEN FIND OUT? TO HELP YOU
ANSWER THAT QUESTION, WE LAUNCHED A TOOL CALLED
LIGHTHOUSE. LIGHTHOUSE GUIDES YOU ALONG YOUR PWA JOURNEY AND
RUNS OVER A HUNDRED AUDITS AGAINST YOUR WEB APP CHECKING
EVERYTHING FROM PAGE PERFORMANCE
TO BYTE EFFICIENCY TO ACCESSIBILITY. AND IT EVEN
GIVES YOU A SCORE FROM ZERO TO A
HUNDRED. SO IF YOU WANT TO BRAG ABOUT
YOUR GREAT LIGHTHOUSE CORE ON TWITTER, YOU CAN. IT REALLY
DOES SEEM TO GET THE COMPETITIVE
JUICES FLOWING. AND YOU WANT TO
TAKE ALL OF THE GOODNESS OF LIGHTHOUSE AND MAKE IT AS EASY
FOR EVERYONE TO USE AS POSSIBLE AND SO WE'RE INTEGRATING
LIGHTHOUSE RIGHT INTO CHROME DEVELOPER TOOLS.
SO YOU CAN JUST OPEN IT UP, AND YOU SEE A LIGHTHOUSE AUDIT
RIGHT THERE.
WHETHER YOU WANT TO TWEET YOUR SCORE OR NOT, I'LL LEAVE UP TO
YOU.

SO HOW DO YOU GET A GREAT
LIGHTHOUSE SCORE? WELL, FOR ONE THING, YOUR APP
WILL NEED TO WORK WELL WHEN YOU'RE OFF LINE OR ON A FLAKY
NETWORK. AND THERE'S A POWERFUL
TECHNOLOGY BAKED INTO BROWSERS CALLED SERVICEWORKER THAT
ENABLES THIS. BUT SERVICEWORKER IS QUITE A
LOW-LEVEL API AND CAN BE HARD TO
WORK WITH DIRECTLY. SO TO HELP YOU TAKE FULL ADVANTAGE OF THE
POWER OF SERVICEWORKER, I'D LIKE
TO INTRODUCE WORKBOX. WORKBOX IS A TOOL THAT WE HAVE
BUILT THAT ENABLES YOU TO TAKE — TO GET THE MOST OUT OF
SERVICEWORKER. IT BUILDS UPON EXISTING TOOLS AND IT
SIMPLIFIES A NUMBER OF COMMON PATTERNS AND
BEST PRACTICES, THINGS LIKE FLEXIBLE CACHING, OR MANAGING
BACKGROUND SYNC OR EVEN COLLECTING USER STATS WHEN THE
USER IS OFF LINE. AND WORKBOX IS COMPLETELY
MODULAR AND FLEXIBLE SO THAT YOU
CAN JUST TAKE WORKBOX, INTEGRATE
IT INTO YOUR EXISTING TOOLS AND START USING IT RIGHT AWAY.
BUT DO REALLY MAX OUT THAT LIGHTHOUSE SCORE, YOUR APP WILL
NEED TO DO MORE THAN JUST WORK OFF LINE.

IT WILL NEED TO BE
FAST. AND THIS MEANS THAT YOU NEED TO BE ABLE TO BUILD AND
LOAD YOUR RICH, COMPLEX APPLICATION WITH AS LITTLE
EXTRA OVERHEAD AS POSSIBLE.
WEB COMPONENTS ARE A WAY TO BUILD LIGHTWEIGHT USABLE PIECES
OF YOUR APP WITH VERY LITTLE OVERHEAD. YOU CAN CREATE YOUR
OWN COMPONENTS OR YOU CAN REUSE ONE OF THE THOUSANDS OF
COMPONENTS THAT ALREADY EXIST.

REMEMBER THOSE AMAZING AMP
PERFORMANCE NUMBERS? AMP IS BASED ON WEB COMPONENTS. AND
JUST LIKE WE BUILT WORKBOX TO HELP YOU GET THE MOST OUT OF
SERVICEWORKER, WE BUILT POLYMER TO HELP YOU GET THE MOST OUT OF
WEB COMPONENTS. AND I'M HAPPY TO ANNOUNCE TODAY
THE LAUNCH OF POLYMER 2.0, THE NEXT MAJOR EVOLUTION OF THE
POLYMER LIBRARY. [ CHEERS AND APPLAUSE ] IT IS A GROUND-UP RETHINK THAT
IS BUILT TO TAKE FULL ADVANTAGE OF THE BEST NEW FEATURES OF THE
MODERN WEB PLATFORM. IT USES THE NEW WEB COMPONENT APIs
THAT HAVE SHIPPED IN CHROME AND SAFARI.
IT EMBRACES ES6 CLASSES. IT IS COMPLETELY MODULAR. AND BEST
OF ALL, IT'S 10% FASTER AND 80%
SMALLER. SO TO TAKE A LOOK AT SOMEONE WHO HAS USED POLYMER TO
BUILD A GREAT PROGRESSIVE WEB APP WITH A GREAT LIGHTHOUSE
SCORE, LET ME INVITE UP ON STAGE
DIPIKA KAPADIA AND RATUL ROY FROM OLA CABS.
[ APPLAUSE ] Dipika Kapadia: HI, EVERYONE.

I'M DIPIKA KAPADIA, HEAD OF CONSUMER WEB PRODUCTS.
Ratul Roy: I'M RATUL ROY, PRINCIPAL ENGINEER.
Dipika Kapadia: WE ARE HERE ALL
THE WAY FROM BANGALORE AND REALLY EXCITED TO TELL YOU
ABOUT OLA AND OUR PWA.
OLA IS INDIA'S LARGEST RIDE-HAILING SERVICE WITH A
MISSION TO PROVIDE MOBILITY FOR A BILLION INDIANS. WE STARTED
SIX YEARS AGO OUT OF A LITTLE APARTMENT IN MUMBAI. AND IN
THOSE DAYS, OUR CO-FOUNDER WOULD
ACTUALLY DRIVE CUSTOMERS AROUND WHEN THEIR RIDE DIDN'T SHOW UP. TODAY WE DO OVER A MILLION
DAILY RIDES. BUT EVEN THAT'S NOT
ENOUGH WHEN YOUR MISSION IS TO MOVE A BILLION INDIANS AROUND.
IN ORDER TO DO THAT, WE NEEDED TO REACH TIER 2, TIER 3 CITIES,
SMALLER CITIES WITH FLAKY NETWORKS WHERE USERS HAVE
LOW-END SMARTPHONES WITH SLOW FRAMEWORK
PROCESSORS AND LOW MEMORY.

THAT'S THE REASON WE BUILT THIS
PWA. WE WOULD LOVE TO SHOW YOU WHAT WE BUILT, SO LET'S GO TO
DEMO WITH RATUL DRIVING. RATUL, LET'S ASSUME WE'RE BACK
IN BANGALORE AFTER AN AWESOME I/O EXPERIENCE AND NEED TO GET
A RIDE FROM THE AIRPORT BACK TO
THE OFFICE. WILL YOU CALL A SUV?
Ratul Roy: SURE, DIPIKA. I'M LAUNCHING THE PWA FROM THE HOME
SCREEN.

IT'S FAST, ISN'T IT? IT'S
ASKING FOR THE BROWSER LOCATION PERMISSION. BUT I'M GOING TO
GO AHEAD AND CHOOSE OTHER LOCATION
FROM MY SAVED FAVORITES. SO I'LL BE TAKING CAB FROM
AIRPORT TO WORK. THE REASON I
COULD DO IT SO FAST IS BECAUSE I
SAVED ALL THE LOCATION AS MY FAVORITES. IF YOU HAVEN'T,
STILL YOU CAN GO AHEAD AND WHILE
SEARCHING THE ADDRESS BAR FOR THE LOCATION OR YOU CAN LOAD IT
IN THE MAP AND NAVIGATE THROUGH.
IF YOU HAVE NOTICED, IN ORDER TO
SAVE DATA, WE LOAD THE MAP ONLY WHEN YOU NEED TO.
HERE ARE THE RIDES, DIPIKA.

WE HAVE A SUV AVAILABLE IN FIVE
MINUTES. Dipika Kapadia: COOL. BUT
WHAT KIND OF RIDE ARE WE GOING TO
GET? Ratul Roy: SURE, HAVE A LOOK
HERE. Dipika Kapadia: SWEET. I
THINK EXTRA LEG ROOM AFTER THIS LONG
FLIGHT BACK FITS THE BILL. Ratul Roy: SURE.
Dipika Kapadia: SO, GUYS, SO FAR YOU'VE SEEN OUR PWA IS AN
IMMERSIVE, FULL-PAGE EXPERIENCE THAT'S RESPONSIVE TO THE TOUCH,
LOADS REALLY FAST, AND SUPPORTS BACK-BUTTON NAVIGATION MUCH
LIKE A NATIVE APP.
SO WHAT DO YOU SAY, GUYS? SHALL
WE BOOK A REAL-LIVE CAB IN BANGALORE? IT'S ABOUT 5:00
A.M. THERE.
[ LAUGHTER ] AWESOME.
RATUL, DO THE HONORS, PLEASE. Ratul Roy: SURE. LET ME TRY.
I'M CONFIRMING THE BOOKING TO PICK UP.
Dipika Kapadia: GO FOR IT. OOPS, THERE YOU HAVE IT, GUYS,
THIS IS A REAL-LIVE BOOKING IN BANGALORE THAT WE JUST MADE.
THANK YOU SO MUCH, RATUL. Ratul Roy: SURE.
[ APPLAUSE ] Dipika Kapadia: NOTHING RIGGED
HERE. YOU BETTER CANCEL THAT BOOKING
BEFORE HE GETS MAD AND SHOWS UP.
[ LAUGHTER ] Ratul Roy: LET'S
(INDISCERNIBLE). Dipika Kapadia: AWESOME.
OKAY.

SO THE OLA PWA IS ONLY A HALF
MEG, OF WHICH THE APPLICATION CODE IS JUST 200KB.
SO HOW DID WE BUILD THIS REALLY PERFORMANT APP WITH SUCH A
SMALL SIZE?
LET'S LOOK AT THAT. FIRST, WE USED THE POLYMER
FRAMEWORK, WHICH LEVERAGES CHROME OR OTHER BROWSER
RESOURCES, AND GIVES US BLAZING-FAST WEB COMPONENTS,
DOM AND CSS CAPSULATION, SUFING
SHADOW.COM, AND HTML SHADOW PORT, FOR A VERY EFFICIENT
40KB. NEXT, LET'S TALK ABOUT THOSE
FAST LOAD TIMES. WHAT YOU SAW RIGHT NOW IN THE
DEMO WAS THE REPEAT CACHED EXPERIENCE OF THE HOME SCREEN.
BUT WE HAVE A REALLY ENVIABLE FIRST LOAD TIME OF ONE TO THREE
SECONDS, DEPENDING ON THE NETWORK, INCLUDING LOW 3G,
WHICH IS WHERE OUR TARGET AUDIENCE
LIVES. LET ME SHOW YOU HOW.
AS YOU CAN SEE ON THE LEFT SIDE HERE, WE LOAD OUR WEB
COMPONENTS VERY STRATEGICALLY, USING A
WATERFALL MODEL, SO THAT WE'RE ONLY FETCHING THOSE COMPONENTS
THAT THE USER NEEDS TO SEE FOR HIS FIRST INTERACTION WITH OUR
PWA. WE'RE FETCHING IN THE
BACKGROUND THE OTHER RESOURCES HE NEEDS TO
ENSURE THAT THE EXPERIENCE STAYS
SNAPPY GOING FORWARD.

ONCE WE'VE LOADED ALL THE
COMPONENTS, USING WORKBOX, WE PRE-CACHE ALL OF THESE, SO THAT
THE REPEAT LOAD TIME STAYS UNDER
A SECOND. FROM THIS POINT ON, THE ONLY
SERVER CALL THAT WE ARE MAKING IS TO FETCH DATA, SUCH AS
REAL-TIME CAB AVAILABILITY, MAKING A BOOKING, ET CETERA.
ALL OF THIS STAYS UNDER ABOUT 5KB. WE ALSO LEVERAGE LIGHTHOUSE.
[ APPLAUSE ] AND WEB PAGE TEST. AND WE ARE
PLANNING TO INTEGRATE LIGHTHOUSE
IN OUR BUILD, BECAUSE, OBVIOUSLY, WE'LL ADD MORE
FEATURES TO THE APP. SO HERE YOU CAN SEE OUR LIGHTHOUSE
CORE. WE ARE VERY, VERY PROUD OF THIS CORE. AND WE OPTIMIZE FOR A
PERFECT SCORE. AND WE CAN TOTALLY RELATE TO DEVELOPERS
WANTING TO TWEET AND BRAG ABOUT THEIRS.
SO HOW'S OUR PWA DOING FOR US? WELL, WE'VE BEEN OUT FOR ABOUT
A MONTH NOW, AND WE ARE SEEING
THAT OUR CONVERSION, OUR RIDES BOOKED IN TIER 2 CITIES, IS
COMPARABLE TO OUR NATIVE APP.

BUT WHAT'S GREAT TO SEE IS THAT
IN TIER 3 CITIES, SMALLER CITIES, OUR CONVERSION IS
ACTUALLY 30% HIGHER THAN OUR NATIVE APP, WHICH SHOWS THAT,
CLEARLY, WE ARE SOLVING FOR NETWORK ISSUES AND THE NEED FOR
LOW DATA USAGE, WHICH IS INHERENT IN THESE GEOGRAPHIES.
WE'VE ALSO SEEN MOBILE TRAFFIC INCREASE BY 68% IN THESE CITIES
SINCE WE LAUNCHED, WHICH SHOWS THAT WE ARE EXPANDING OUR REACH.
BUT WHAT SURPRISED EVEN US IS THAT 20% OF OUR PWA BOOKINGS
COME FROM USERS WHO HAVE PREVIOUSLY UNINSTALLED OUR
NATIVE APP. SO THIS SHOWS THAT OUR PWA CAN EVEN BE A GREAT
RE-ENGAGEMENT TOOL. SO THERE YOU HAVE IT, GUYS.
OUR PWA HAS BEEN A WIN-WIN FOR OUR
CUSTOMERS AND FOR OLA. SO I HOPE SHARING OUR JOURNEY
INSPIRES MANY OF YOU TO BUILD YOUR OWN PROGRESSIVE WEB APP,
AND THE NEXT TIME YOU'RE IN INDIA, REMEMBER TO BOOK YOUR
RIDE ON OLA.

[ LAUGHTER ]
[ APPLAUSE ] Ratul Roy: THANK YOU.
Dipika Kapadia: THANK YOU. HERE YOU GO, RAHUL.
Rahul Roy-Chowdhury: GREAT. THANK YOU, DIPIKA AND RATUL.
AND CONGRATULATIONS TO THE TEAM AT OLA.
SO, FOLKS, THERE YOU HAVE IT, AMAZING MOMENTUM ON THE CORE
PILLARS OF THE MODERN MOBILE WEB, AMP, AND PWAS.
NEW APIs, UNLOCKING NEW EXPERIENCES AND NEW USE CASES,
EVERYTHING FROM INSTALLING WEB APPS TO YOUR DEVICE, TO PAYING
FOR THINGS ON THE WEB, TO POLISHED MEDIA EXPERIENCES.
AND LOOKING AHEAD, COMPUTING CONTINUES TO EVOLVE AT A FAST
CLIP. AND WE AT GOOGLE WANT TO MAKE SURE THAT WE CAN HELP
DEVELOPERS TAKE ADVANTAGE OF THESE CHANGES, WHETHER THEY'RE
BUILDING NATIVE APPS OR BUILDING
FOR THE WEB. AND JUST LIKE WE DO WITH NATIVE
APPS, WE WANT THE WEB TO BE A GREAT PLATFORM FOR FUTURE
TECHNOLOGIES AS THEY EVOLVE. ONE SUCH FUTURE TECHNOLOGY IS
VR. VIRTUAL REALITY ENABLES THE
CREATION OF RICHLY-IMAGINED WORLDS THAT YOU CAN FULLY
IMMERSE YOURSELF IN. AND THROUGH THE WEBVR API, ALL OF
THIS EXPRESSIVE POWER IS AVAILABLE ON THE WEB.

WEBVR
ENABLES COMPANIES LIKE WITHIN TO
SHOWCASE THESE AMAZING VR EXPLORATIONS FROM CREATORS
AROUND THE WORLD, RIGHT IN YOUR BROWSER.
WEBVR ENABLES COMPANIES LIKE SKETCH PAD TO BRING YOU THESE
AMAZING STUNNING VR SCENES TO EXPLORE. THEY HAVE OVER ONE
AND A HALF MILLION OF THESE.
NOW, THESE WOULD BE TRULY MIND-BLOWING IF YOU ALL HAD VR
HEADSETS ON. BUT YOU GET A SENSE OF WHAT IS POSSIBLE.
WEBVR IS NOW FULLY SUPPORTED IN CHROME, AND MOST MAJOR BROWSER
VENDORS HAVE ANNOUNCED THEIR SUPPORT AS WELL.
AND LOOKING EVEN FURTHER AHEAD, WE SEE THE ADVENT OF AR,
AUGMENTED REALITY, A WAY TO CONNECT INFORMATION TO THE
PHYSICAL WORLD. SO NO MATTER HOW COMPUTING
EVOLVES AND CHANGES IN THE FUTURE, THE WEB WILL ALWAYS BE
HERE AS A WAY FOR YOU TO REACH YOUR USERS AT SCALE.
IF YOU WANT TO DIG IN MORE, WE HAVE A LOT OF GREAT SESSIONS ON
THE MOBILE WEB AT I/O THIS YEAR.
AND EVEN AFTER I/O IS DONE, COME
AND TALK TO US.

TELL US WHAT YOU'RE WORKING ON. TELL US
WHAT YOUR CHALLENGES ARE. WE ARE
HERE TO HELP YOU BE SUCCESSFUL ON THE WEB.
IT'S AMAZING TO SEE HOW FAR WE'VE COME OVER THE LAST 12
MONTHS. THE MODERN MOBILE WEB IS NOW MAINSTREAM, AND I CAN'T
WAIT TO SEE WHAT HAPPENS IN THE NEXT 12 MONTHS.
THANK YOU VERY MUCH. [ APPLAUSE ] Ben Poiesz: HI, EVERYBODY.
I'M BEN POIESZ, I'M THE PRODUCT
MANAGER FOR ANDROID FRAMEWORK. I LIKE HOW EVERYBODY IS RIGHT
OVER THERE. I WISH I COULD JOIN
YOU. THE SUN IS GOING TO COME AND GET ME.
WHAT I WANT TO TALK TO YOU GUYS ABOUT IS BACKGROUND LIMITS AND
A LOT OF THE INFRASTRUCTURE THAT
WE'VE PUT IN PLACE IN O, AND IT IS A STARTING POINT. AND I
WANTED TO TRY AND HAVE THIS TALK
TO GIVE YOU A GLIMPSE OF HOW WE'RE APPROACHING THE PROBLEM
AND SO YOU DON'T JUST THINK WE'RE TRYING TO RUIN ALL THE
APPS AND EVERYTHING YOU'RE DOING
IN THE BACKGROUND.

WE'RE ACTUALLY TRYING TO FIND A
BALANCE OF ENABLING USERS TO HAVE BETTER LIFE THEY CAN RELY
ON AND HAVE DEVELOPERS DO THE USE CASES THAT THEY TRI-ARE
GREAT AND RESPOND.WILL TO. AT THAT DO THAT, WE'RE GOING TO
TALK A BIT ABOUT THE PAST, A LOT
ABOUT THE PRESENT, AND A LITTLE BIT ABOUT THE FUTURE AND WE'LL
GIVE A GLIMPSE OF THE SPACE WE'RE TRYING TO GO LONGER TERM.
SO IN THE PAST, WE HAVE DOZE AND
STANDBY. DOZE AND DOZE LITE WERE INTRODUCED TO TRY AND SAVE
BATTERY IN TWO MAIN CONDITIONS, OFF
FOR A LONG PERIOD OF TIME. A GOOD EXAMPLE IS I TAKE MY
TABLET, I TOSS IT IN MY DESK AND
IT SITS THERE FOR A FEW DAYS. YOU REALLY WANT THE DEVICE TO
LAST A LONG TIME AND DOZE WAS INTRODUCED TO MAKE THAT DEVICE
LAST FOR UP TO A WEEK. IT WAS LARGELY SUCCESSFUL WHEN IT WAS
INTRO INTRODUCED. DOZE LITE WAS
TRYING TO TAKE THAT SAME CONCEPT
AND APPLY IT TO MY PHONE IS IN MY POCKET, IT'S NOT ON BUT IT
IS ON ME.

AND DOZE WASN'T
IDENTIFYING THAT SITUATION. AND
DOZE LITE WAS TRYING TO TARGET THAT. AND TO START SLOWING
DOWN APPLICATIONS AND LIMITING WHAT
WAS HAPPENING THROUGHOUT THE DAY. APP STANDBY WAS SIMILAR
IN CONCEPT IS THE USER INTERACTING
VERY OFTEN AND IF NOT, BEGIN THROTTLING THAT BACK.
WE ALSO LOOKED AT BROADCAST REMOVAL, AND THIS IS WHEN WE
TARGETED AN INITIAL SET OF THREE
PARTICULAR BROADCASTS. AND THE BEST EXAMPLE OF THIS WAS WE
WERE FINDING YOU TAKE A PHOTO AND
SUDDENLY ALL THE APPLICATIONS ARE GETTING REALLY EXCITED
ABOUT THAT PHOTO BECAUSE IT'S
LISTENING TO THAT BROADCAST.

THEY WOULD ALL BE WAKING UP A
WHAT'S GOING ON WITH THE PHOTO? SHOULD I BACK IT UP? WHAT
SHOULD HAPPEN? THE USER IS LIKE, I AM REALLY TRYING TO
TAKE A PHOTO. GOD FORBID SHOULD YOU
TAKE TWO PHOTOS. THE SECOND PHOTO IS NOW THIS RESOURCE
CONTENTION. AND SO WE FOUND THIS WAS REALLY SUCCESSFUL TO
PULL THESE GUYS BACK FROM BEING THESE GENERAL BROADCASTS ANNEX
STEAD BEING A BIT MORE — INSTEAD BEING MORE TARGETED.

THAT'S THE LEAD-IN TO THE PRESENT WHEN WE STARTED LOOKING
AT A GENERAL STRATEGY FOR BACKGROUND LIMITS. I WILL ALSO
TALK ABOUT ALERT WINDOW WHICH IS
A SIMILAR PROBLEM SPACE. AND A BIT HOW WE ARE TRYING TO BRING
A DATABASE APPROACH TO IMPROVING
SYSTEM HEALTH ON ANDROID. I DON'T MEAN HEALTH LIKE MY
PERSONAL HEALTH, BUT MORE LIKE THE DEVICE HEALTH.
AND THEN I'LL PEPPER IN A FEW BEST PRACTICES AS WE GO
THROUGH. SO BACKGROUND LIMITS. WHY? SO
WHAT WE'RE TRYING TO DO IS TWO PARTS. ONE IS TO SAVE BATTERY. THIS ONE WAS LARGELY AROUND THE
LIMITS THAT WE PUT IN PLACE FOR LOCATION AND THE GOAL THAT
WE'RE TRYING TO GET AT IS WE WANT
MULTIDAY BATTERY LIFE. THAT'S WHAT'S GOING TO TAKE US A WHILE
TO GET THERE. BUT THAT'S WHAT WE'RE TRYING TO GO.

AND TO DO
THAT, WE KNOW WE HAVE A PRETTY LARGE TASK IN TERMS OF WHAT'S
HAPPENING IN THE BACKGROUND. IT'S A NEARLY 6 TO 8%
EFFICIENCY IMPROVEMENT FROM WHERE WE ARE
TODAY. THAT'S LIKE THE BACKDROP, IF YOU WILL OF HOW
WE'RE THINKING ABOUT IT. AND THESE ARE THE KIND OF INITIAL
STEPS IN SETTING THE FRAMEWORK FOR HOW WE'RE GOING TO GET
THERE. THE OTHER PART IS ABOUT RAM
MANAGEMENT AND WORKING ON HOW BROADCASTS ARE BEING FIRED TO
APPLICATIONS AND ALSO DEALING WITH HOW APPLICATIONS ARE
RUNNING IN THE BACKGROUNDS WITH LONG-RUNNING SERVICES.
SO JUST TO GIVE YOU A CONCRETE EXAMPLE OF THIS IS YOU HAVE
THIS CHART OF SCREEN-OFF PERFORMANCE
OVER TIME. AND THE ONE THING YOU CAN SEE UP HERE — I CAN'T
SEE MY MONITORS ANYMORE. THE SUN HAS TOTALLY KILLED ME UP
THERE. THE ONE THING YOU CAN SEE UP
THERE IS OVER TIME YOU'RE GOING TO HAVE A SLIDE OF YOUR
SCREEN-OFF BATTERY PERFORMANCE, THE LONGER THE PHONE IS IN THE
FIELD.

YOU'LL ALSO SEE THAT THE
JANK RATES, THE SLOW UI FRAMES, GET HIGHER THE LONGER THE
DEVICE IS IN THE FIELD. AND SO THESE
ARE THINGS THAT WE REALLY WANT TO HELP REMEDY AND ADD
ROBUSTNESS INTO THE PLATFORM SO WE CAN REALLY SMOOTH THESE OUT. LIKE, OBVIOUSLY WE'RE TALKING
DEVICE'S AGE AND PHYSICS COMES INTO PLAY AND THE MARCH TIME
HAPPENS BUT WE DON'T WANT THEM TO BE ANYWHERE NEAR THAT STEEP.
ANOTHER EXAMPLE IS AS A DEVICE IS ON IN THE COURSE OF EVEN
DAYS, THIS ONE IS MEASURED ALL — INITIALLY HOURS AND THEN
IN DAYS, YOU CAN SEE JUST UPTIME
STARTS TO TAKE A TOLL ON THE DEVICE.
AND SO THESE ARE THE THINGS WE'RE REALLY TRYING TO TARGET
AND IMPROVE.

SO LET'S DIG IN A LITTLE BIT TO
SOME OF THE CHANGES THAT WE'RE INTRODUCING.
BACKGROUND LIMITS ON THE SAVE RAM PART IS WE WANT TO RESTRICT
SERVICES AND BROADCASTS AND WE WANT TO REDUCE THE AMOUNT OF
CHURN THAT'S HAPPENING ON THE DEVICE. AND TO SAVE BATTERY,
WE'RE LOOKING TO IMPROVE BACKGROUND LOCATION SCAN RATES
AND WiFi SCAN RATES AND TO REDUCE THEM AND MAKE THEM BE
MORE OF A TRICKLE THAN THESE BURSTY EVENTS THAT WE'RE SEEING
HAPPENING IN THE ECOSYSTEM. SO FOR BACKGROUND LIMITS, THE
BIG ONE HERE IS WE WANT TO REDUCE THAT RAM USAGE.

TO DO
THAT IS — WELL, THIS SLIDE IS THE SAME. I SHOULD SKIP.
SO HOW WE'RE DOING THAT IS WITH BROADCAST RECEIVERS. BY
PULLING THESE GUYS BACK YOU ARE ABLE TO
THEN SAY, OKAY, ALL THESE BROADCASTS THAT ARE IMPLICIT
ARE GOING TO BE SILENCED. IF YOU
ARE NOT CURRENTLY RUNNING, WE'RE
NOT GOING TO WAKE YOU UP FOR THEM EXCEPT IN THE CASE WHERE
THEY ARE EXPLICIT. WE SAY SOMETHING IMPORTANT HAS
HAPPENED OR YOU HAVE BEEN TARGETED OR
REGISTERED FOR SOME WAKEUP AND THOSE THINGS WILL STILL WORK
COMPLETELY AS NORMAL AS THEY DID
BEFORE. SO THAT FOLLOWS ALARMS AND NOTIFICATIONS.
OTHER ONES THAT WE'RE STILL KEEPING AROUND, BOOT COMPLETE,
LOCALE CHANGING AND THESE ARE REALLY EVENTS THAT ARE NOT
HAPPENING AS THE USER'S TRYING TO DO SOMETHING ELSE. THAT'S
REALLY BEEN THE TARGET OF HOW WE
APPROACH WHICH THINGS SHOULD CONTINUE TO WORK AND WHICH
THINGS SHOULD WE START DEFERRING.
THE OTHER ONE HERE IS FREE RUNNING BACKGROUND SERVICES
SHOULD NO LONGER BE A THING.

AND THE IDEA BEHIND THAT IS WE
WANT USERS TO HAVE VISIBILITY TO
WHAT'S HAPPENING ON THEIR PHONE.
AND SO IF AN APPLICATION IS DOING SOMETHING REALLY
EXPENSIVE IN THE BACKGROUND, WE WANT
THERE TO BE SOME AWARENESS FOR THE
USER. WE DON'T WANT THE DEVICE TO BE TOILING AWAY IN THE
BACKGROUND WITHOUT ANY AWARENESS. THIS MEANS WE WANT
TO START STOPPING THOSE SERVICES
AFTER THEY'RE RUNNING FOR A LITTLE BIT.

WE WANT TO START
THROWING — WE WILL START THROWING AN EXCEPTION IF YOU
TRY TO START A BACKGROUND SERVICE
WHEN YOU'RE NOT IN THE FOREGROUND OR WHEN YOU DON'T
HAVE A FOREBROWNED SERVICE RUNNING. AND THIS IS ALSO THE
VERY LAST ONE, IS WE START RELEASING WAKELOCKS. YOU STILL
WANT TO MANAGE WAKELOCKS. DON'T
THINK THE OS IS GOING TO HANDLE THEM FOR YOU. WE ARE ADDING
MORE PROTECTIONS IN DIFFERENT SCENARIOS WHERE THEY MIGHT HAVE
BEEN LEAKED OR THE DEVELOPER WAS
A LITTLE LAX IN THEIR CLEANUP. WE STILL HAVE THE WHITE LISTING
WE HAD BEFORE SO THERE WILL BE A
WHITE LISTING STRATEGY THAT'S AROUND WHEN GCM FIRES OFF A
BROADCAST TO YOUR APPLICATION. YOU WILL STILL GET WOKEN UP.
YOU WILL GET A SHORT EXEMPTION TO HANDLE THAT MESSAGE. FROM
THERE YOU CAN KICK OFF A SERVICE, BRING YOUR APPLICATION
TO THE FOREGROUND IF IT'S APPROPRIATE.
OR YOU CAN JUST TAKE THE NOTE, RUN A SCHEDULE A JOB AND ALARM
AND HAVE IT BE SCHEDULED BY THE OS AND HAPPEN WHEN IT HAPPENS.
THERE IS FLEXIBILITY FOR OEMS IF
YOU ARE RELYING ON OEMs SPECIFIC INTENT OR SOME
SPECIFIC BEHAVIOR THAT'S NOT BUILD IN
THE EPS.

THE OEM WILL DEFINE WHICH
MYS ARE EXPLICITS AND IMPLIES SYS IT AND WHICH THINGS CAN BE
FIRED AND WHICH THINGS GET THE BRAKES TAPPED ON THEM. YOU
MIGHT BE THINKING AT THIS POINT,
THE USER PART OF MY BRAIN IS REALLY HAPPY PROBABLY. THE
DEVELOPER SIDE IS GOING, WAIT, I
NEED — I HAVE THINGS TO DO. I HAVE THINGS TO SAY. HOW CAN I
COMMUNICATE TO THE DEVELOPER? LIKE, IT'S REALLY IMPORTANT,
BEN, WHAT ARE YOU DOING? THERE'S A NUMBER OF STRATEGIES
AND I WILL TALK ABOUT THEM RIGHT
NOW ABOUT HOW TO DO THESE OPERATIONS STILL WITH THE USER
ON A TIMELY BASIS AND STILL BE RESPECTFUL OF THE BATTERY BUT
THEN ALSO BE ABLE TO TELL THE USER, NO, I'M DOING SOMETHING
INCREDIBLY IMPORTANT. SO THE FIRST ONE TO LOOK AT IS USING
FIREBASE AND GOOGLE CLOUD MESSAGING AND USING THE HIGH
PRIORITY AND NORMAL PRIORITY MESSAGES.
I HOPE YOU'RE TAKE-AWAY FROM THIS SLIDE IS NOT LIKE FIRE ALL
TORPEDOES AT HIGH PRIORITY.

REALLY WANT YOU TO BE BALANCED
IN SAYING IF SOMETHING IS IMPORTANT, LIKE, SAY, MY FIRE
ALARM IS GOING OFF AT HOME AND I
WANT TO SEND A NOTIFICATION TO THE USER, USE A HIGH-PRIORITY
NOTIFICATION. IT'S KIND OF A BIG DEAL. IF YOU ARE, SAY,
USING A USER IS SCHEDULED FOR A TV SHOW THEY LIKE AND THAT TV
SHOW IS NOW AVAILABLE AND THEY CAN STREAM IT AT THEIR LEISURE,
USE A NORMAL-PRIORITY NOTIFICATION. IT WILL MAKE A
BIG DIFFERENCE IN THE BATTERY LIFE OF THE DEVICE AND IT
REALLY ADDS UP WHEN THE ECOSYSTEM
STARTS TAKING THESE APPROACHES. THE OTHER ONE HERE IS SOMETHING
NEW CALLED THE JOB INTENT SERVICE. THIS IS COMING OUT —
WE JUST MISSED THE WINDOW BUT I STILL WANTED TO TALK ABOUT IT
FOR WHAT CAME OUT WITH THE NEW 26 BETA.

BUT IT WILL BE COMING
OUT SHORTLY BEFORE O LAUNCH. IT'S A STRATEGY OF YOU CAN USE
JOB INTENT SERVICE ON O TO GIVE YOU BACKWARDS COMPAT SUPPORT SO
YOU WILL USE THEN JOBS WHEN YOU'RE ON O AND YOU WILL HAVE
AN AUTOMATIC FALL-BACK TO USING
SERVICES PRE-O. THE REALLY NICE
PART ABOUT THIS WHEN YOU HAVE THAT FALL-BACK, WE WILL HANDLE
THE WAKELOCKS FOR YOU. SO YOU DON'T HAVE TO WORRY ABOUT IF
YOU WILL MAKE A LEAK OR MAKE A
MISTAKE THERE. DEFINITELY LOOK AT THIS WHEN IT COMES OUT. IT
WILL MAKE YOUR LIVES A LOT EASIER TO ADOPT.
THE OTHER LAST ONE IS ABOUT ALARMS, SYNCS AND JOB
SCHEDULING. THESE ARE ALL GOOD STRATEGIES TO RUN JOBS ON A
CADENCE IN THE BACKGROUND THAT GIVES THE OS FLEXIBILITY ABOUT
WHEN IT RUNS. SO I WILL GIVE YOU AN EXAMPLE.
IF ALL THESE APPLICATIONS BEFORE, WHEN WE HAD A WORLD OF
THESE BROADCASTS BEING FIRED AND
THAT APPLICATION CAN START SERVICES, THEY'LL ALL START AT
THE SAME TIME. AND THE OS REALLY HAS ONLY NUKES TO DEAL
WITH THIS PROBLEM. WE CAN ONLY KILL YOUR PROCESS.

THERE'S NO
ABILITY TO THROTTLE. WE CAN'T TRY TO SQUISH RAM. IT'S JUST
YOU LIVE OR YOU DIE. AND WHEN THE RAM BECOMES CONTENTIOUS, WE
START THRASHING PRETTY RAPIDLY. WHEN WHEN YOU ARE USING YOU'RE
USING JOBS AND ALARMS, THE OS HAS NOW
FLEXIBILITY TO DEFER, TO RUN ONE
JOB AT A TIME, A FEW JOBS AT A TIME, AND SPREAD IT OUT ACROSS
THE LIFETIME OF A DEVICE. AND THAT AVOIDS, THEN, RESOURCE
CONTENTION, IT AVOID JANKINESS IN THE BACKGROUND.
I'VE MADE THIS REALLY EXCITING FLOWCHART FOR YOU THAT YOU CAN
LOOK AT IT LATER. THE IDEA BEHIND IT IS ROUGHLY LOOKING AT
WHAT ARE THE DIFFERENT STAGES THAT ARE HAPPENING AND WHAT IS
THE RIGHT CHOICE FOR YOU AS A DEVELOPER AND FOR THE USER TO
HAVE, LIKE, THE — THE BEST, MOST EFFICIENT EXPERIENCE FOR
THE USE CASE THAT YOU'RE TRYING TO ACHIEVE.
YES, THE END OF THIS IS MAYBE YOU SHOULDN'T DO IT IN THE
BACKGROUND.

AND THAT'S THE ONE I REALLY WANT YOU TO FOCUS ON,
IS THINK ABOUT DO I REALLY HAVE TO BE DOING THIS? IS THE USER
GOING TO UNDERSTAND WHAT I'M TRYING TO DO?
IF THE USER IS GOING TO UNDERSTAND WHAT YOU'RE TRYING
TO DO, AND A GREAT EXAMPLE OF THIS
ARE, LIKE, NAVIGATION APPS, MUSIC-PLAYING APPS, VARIOUS
EXERCISE APPLICATIONS, ALL OF THOSE SCENARIOS, IF YOU'RE
RUNNING A FOREGROUND SERVICE AND
THE USER SEES A NOTIFICATION, IT'S GOING TO MAKE SENSE TO
THEM. YOU'RE GOING TO BE REALLY
WELL ALIGNED. SO IN THOSE SCENARIOS, PLEASE
GO DO THAT.
IN OTHER ONES, WHERE YOU'RE, LIKE, I DON'T KNOW HOW TO
EXPLAIN THIS TO A USER, THEN YOU
SHOULD DEFINITELY BE CONSIDERING
JOBS OR BE NOT CONSIDERING RUNNING IT IN THE BACKGROUND AT
ALL. TRANSITIONING, THAT WAS THE
BATTERY SAVING AND EXECUTION PORTION. NOW I'M GOING TO
TRANSITION A LITTLE BIT TO TALK ABOUT LOCATION LIMITS.
AND THE IDEA HERE WAS TO PUT SOME UPPER BOUNDS ON WHAT WE'RE
SEEING IN THE BACKGROUND AROUND GEOFENCING, POLLING, AND
OTHERS.

AND IT WAS CAUSING, REALLY, A
SIGNIFICANT AMOUNT OF DRAIN. AND THE REASON IS, LOCATION IS
POWER-HUNGRY. AND THERE WERE REALLY NO FUNCTIONAL LIMITS ON
WHAT AN APPLICATION COULD DO WHEN IT'S IN THE BACKGROUND
WITH RESPECT TO LOCATION.
AND SO IT WOULD END UP WITH TWO DIFFERENT TYPES OF SCENARIOS.
WE'D HAVE — MOST OF THEM, TO BE
HONEST, ARE ACCIDENTAL. ONE BEING IS THAT APPLICATIONS ARE
AGGRESSIVELY REQUESTING LOCATION. AND THIS COULD BE
BECAUSE THEY — THEY'RE INTERESTED IN WHERE YOU ARE, OR
THEY HAVE A PARTICULAR USE CASE.
BUT THE ONE THAT WAS REALLY SAD WAS THIS IDEA OF LEAKS, IS THAT
IF YOU'RE RUNNING IN THE FOREGROUND, YOU'RE — SAY
YOU'RE NAVIGATING, YOU'RE GOING TO
HAVE A REALLY HIGH RATE OF QUERY.
AND WHEN YOU GO TO THE BACKGROUND, THAT HIGH RATE
MAYBE ISN'T NECESSARY ANYMORE. AND
THE INTENTIONAL OF THE DEVELOPER
WAS TO REDUCE IT. BUT FOR ONE REASON OR ANOTHER, MEMORY LEAKS
OR WAKELOCK LEAKS, IT'S STILL RUNNING FULL BLAST. AND WE SAW
THAT A LOT, A LOT OF APPLICATIONS EVERY SECOND
GETTING A LOCATION REQUEST. THAT'S GOING TO COMPLETELY
DESTROY BATTERY.

THOSE ARE THE TWO AREAS WE'RE TRYING TO
TARGET HERE.
THE IDEA NOW IS NOT TO SAY THAT YOU CAN'T RUN IN THE
BACKGROUND. WE'RE TILL ENABLING THAT . BUT
THE IDEA IS TO SPACE IT OUT, ONCE EVERY 30 MINUTES WITH A
CYCLE OF ACCURACY WITHIN TWO MINUTES WITHIN THOSE 30-MINUTE
UPDATES. YOU CAN THINK OF IT AS
A 30-PLNT DELAY WITH AN UPDATE ACCURACY OF TWO MINUTES WITHIN
THAT 30-MINUTE CYCLE. THE SAME WITH WI-FI. THE API
IS A LITTLE BIT DIFFERENT . WE
DON'T HAVE THE CONVENIENCE FOR SCHEDULING. BUT IF YOU'RE
BANGING ON THE WI-FI QUERY, YOU'LL KEEP GETTING THE SAME
RESULTS IF YOU GO TOO FAST. WE WON'T ACTUALLY DO THE QUERY.
THOSE ARE THE TWO STRATEGIES THAT WE TAKE IN FOR LOCATION
AND FOR WI-FI.
JUST TO HIGHLIGHT, THERE'S A NUMBER OF OPTIONS HERE HIS OR
HER LOWER BATTERY IMPACTING THAT
YOU SHOULD BE LOOKING AT.

ONE IS BATCHING, GEOFENCING, AND IN
THE COMPLETE LAST CASE AGAIN IS SERVICE. IF YOU ARE USING THE
FOREGROUND SERVICE AND THE USER UNDERSTANDS WHAT IS KIND OF
HAPPENING, THAT'S REALLY CRITICAL. IF THEY UNDERSTAND
WHAT'S HAPPENING, THAT WILL ENABLE THEM TO SAY, YOU'RE
RUNNING IN THE BACKGROUND. YOU'RE EXPENSIVE. I GET IT,
MOVING ON. AND YOU'LL HAVE RELAXED
REQUIREMENTS WHEN YOU'RE IN THAT
MODE. SO THE OTHER THING I WANTED TO
TALK ABOUT — I KNOW IT FEELS LIKE I'M TALKING ABOUT BATTERY,
AND THEN SUDDENLY I'M TALKING ABOUT ALERT WINDOW.

I WANT TO
TAKE A MOMENT TO THINK TALK ABOUT IT.
TO BE BRUTALLY HONEST WITH YOU, THIS WAS ONLY INTENDED FOR
WHAT THE NAME IS, SYSTEM ALERT
WINDOWS. IT WAS NEVER REALLY CONSCIOUSLY INTENDED TO BE USED
THE WAY THAT IT HAS BEEN. BUT WE WERE IN A SIMPLER WORLD IN
API ONE, AND IT WAS LEFT PUBLIC.
AND PEOPLE HAVE FOUND REALLY AMAZING IDEAS AND SOLUTIONS
USING THIS API. SO WE DON'T WANT TO GET RID OF IT.
HOWEVER, WE DO WANT TO TRY AND PUT IT ON RAILS. WHAT WE'RE
REALLY WORRIED ABOUT IS, MANY APPLICATIONS RENDERING ON TOP
OF EACH OTHER, CONFLICTING WITH
EACH OTHER. THERE'S NO ATTRIBUTION OF WHAT
APPLICATIONS HAPPEN TO BE RENDERING AT ANY
POINT IN TIME. AND SO THE IDEA WAS THAT CAN WE
ADD SOME LAYERING? CAN WE ADD SOME ATTRIBUTION WITHIN THE
MODEL? AND THAT'S WHAT WE DID WITH THE APPLICATION OVERLAY.
SO THE IDEA HERE IS, WITH AN APP
OVERLAY, IS THE USER CAN NOW MANAGE WHAT IS FLOATING ABOVE
THE — THEIR APPLICATION ACTIVITY.

IT'S Z-ORDERED
PROPERLY UNTO THEMSELVES, AND TO
SYSTEM UI AND TO THE APPLICATION
BELOW. AND IT WILL AUTOMATICALLY SHOW A FOREGROUND NOTIFICATION IN THE
NOTIFICATION MENU, SO THE USER IS AWARE IF
THEY'RE IN MULTIPLE APPLICATIONS
SIMULTANEOUSLY USING THIS FEATURE.
THIS WAY, IF THEY SEE IT, THEY'RE UNHAPPY WITH IT, THEY
CAN GO TO THE APPLICATION, CONTROL THE SETTINGS IF THEY
WANT. YOU SHOULD ALWAYS MAKE SURE YOUR USERS ARE AWARE OF
USING THIS, BECAUSE IT CAN BE KIND OF SURPRISING IF IT
DOESN'T HAPPEN.
AND THE OTHER THING THAT WE CHANGED WAS FOR TARGETING ON O
IS, IF YOU ARE NOW USING THIS NEW OVERLAY TYPE, YOU WILL THEN
SEE — SIT ABOVE THE LEGACY VIEWS.

SO THIS IS MAYBE YOUR
INCENTIVE TO ADOPT A NEW MODEL, IS ONCE YOU'RE USING THAT,
EVERYBODY WILL BE PROPERLY Z-ORDERED IN A KIND OF LRU
FASHION. AND THEN YOU'LL — BELOW SYSTEM UI, BUT ABOVE
THINGS LIKE THE KEYBOARD AND OTHER SYSTEM UI COMPONENTS.
SO NOW I WANT TO TRANSITION A LITTLE BIT ABOUT TALKING ABOUT
HOW WE'RE GOING TO IMPROVE THE SYSTEM WITH DATA. AND, YOU
KNOW, I DON'T MEAN TO BLAME ANYONE, 'CAUSE IT'S NOT.
THAT'S NOT MY INTENT. BUT IT'S REALLY
A STORY ABOUT APPLICATIONS. AND
THAT PHONES ARE AMAZING, AND YOU
CAN DO SO MANY THINGS WITH THIS PORTABLE COMPUTING DEVICE.
HOWEVER, WE HAVE RESOURCE SCARCITY, MOSTLY IN THE FRAME
OF BATTERY.
AND THE QUESTION THAT COMES UP, WELL, THEN HOW DO WE BALANCE
THIS? AND THE BIG THING THAT WE
REALIZED — AND YOU MIGHT BE THINKING AT YOUR SEAT, YEAH,
NO, DUH, NO.
THERE ISN'T VERY GREAT TOOLING UP UNTIL RECENTLY TO HELP
DEVELOPERS UNDERSTAND THEIR IMPACT. WHEN WE REACHED OUT
INTERNALLY EVEN AT GOOGLE, WE WOULD FINE THEY DIDN'T REALIZE
THEY WERE DOING IT.

SO THAT KIND OF BROUGHT AROUND A NUMBER
OF THOUGHTS THAT I'LL GET INTO THE OTHER ONE IS THIS KIND OF
TRAGEDY OF THE COMMONS IN THAT YOU HAVE SO MANY APPLICATIONS
ON YOUR PHONE. AND IF ANY OF
THOSE APPLICATIONS SAY STICK A
WAKELOCK, YOU ONLY NEED ONE TO DO IT AND THE COST IS NOW YOUR
CPU IS UNABLE TO GO TO SLEEP. AND YOU'LL HAVE A VERY
PRECIPITOUS DRAIN ON YOUR BATTERY OVER TIME.
AND WHEN YOU HAVE HUNDREDS OF APPS AND ONLY ONE NEEDS TO MAKE
A MISTAKE, YOU'RE PRETTY MUCH GUARANTEED TO HAVE A BAD TIME.

AND SO WHAT WE STARTED LOOKING AT IS HOW CAN WE GET TO A POINT
OF SUSTAINING PERFORMANCE, INTRODUCING ACCURATE
MEASUREMENTS FOR DEVELOPERS AND BRINGING ON LINE NEW
DASHBOARDS. SO LET'S DIG IN A LITTLE BIT
INTO WHAT THESE ARE. AND THERE'S A TALK ON BAD
BEHAVIORS, IT WAS EARLIER IN THE DAY. IF
YOU HAVEN'T SEEN IT, PLEASE GO HOP ON YOUTUBE AND GO TRACH AT
TAKE A LOOK A LOOK AT IT. THE GUYS WHO PRESENTED IT ARE HERE
IN FRONT, STARING AT ME. THANK YOU.
THE BIG ONE HERE IS, WE'RE LOOKING FOR EGREGIOUS BEHAVIOR
THAT WE CAN ALL AGREE ON. SO A GOOD EXAMPLE OF THIS IS
WAKELOCKS. IS IF YOU ASK A DEVELOPER, YOU WERE HOLDING A
WAKELOCK FOR SIX HOURS STRAIGHT.
YOU WERE IN FOUR ROUNDS AND THE USER WASN'T — IN THE
FOREGROUND AND THE USER WASN'T INTERACTING
WITH YOUR APPLICATION. AND PRETTY MUCH EVERYBODY SAYS I
HAVEN'T HAVE BEEN DOING THAT.

THE TRICK WAS, THERE WASN'T
REALLY GOT TO INSTRUMENTATION TO
HELP YOU UNDERSTAND THAT WAS HAPPENING. AND THAT'S WHERE
THE PLAY CONSOLE IS COMING INTO ITS
OWN AND BRINGING OUT THESE FEATURES SO YOU CAN SEE THESE
TYPE OF SITUATIONS THAT ARE HAPPENING.
OTHER BIG ONE HAS BEEN REALLY HE
IS VEERING JANKING FRAMES, SO FROZEN FRAMES, FRAMES THAT DAK
OVER 700 MILLISECONDS TO RUN. ALSO REALLY HARD TO FIGURE OUT
WHERE IN YOUR APPLICATION THEY'RE OCCURRING AND EVEN IF
THEY'RE OCCURRING AND IF THEY ARE, WHAT DRISES THEY'RE
OCCURRING ON. THE LAST WAS CRASH LOOPING AND
CRASH DATES. THE OTHER IS LOOKING AT THE OS
SIDE. NO THE TO SAY THAT EVERYTHING IS ABOUT APPS. IT'S
NOT. WE HAVE TO BRING A LEVEL OF SANITY ONTO THE OPERATING
SYSTEM.

ONE GOOD EXAMPLE WAS THE IMPROVEMENTS WE MADE ON
BOOT TIME AND LOOKING HARD AT HOW
THE OS IS STRUCTURED . AND THE
OTHER ONE IS ALSO GOING TO BE STARTING TO LOOK AT I/O
THROUGHPUT, HOW MANY SCANS ARE HAPPENING IN THE BACKGROUND IN
DIFFERENT PARAMETERS. AND ALL THESE WILL START COMING OUT AND BEING AVAILABLE FOR YOU GUYS
OVER THE COMING YEARS. JUST TO GIVE YOU AN EXAMPLE OF
THIS, I HAVE A SELECTION OF GOOGLE APPS. I HAVE HIDDEN THE
NAMES TO PROTECT THE INNOCENT, SLASH, GUILTY.
BUT WHAT I HAVE PUT UP THERE IS A HASH LINE.

AND THE HASH LINE
IS EFFECTIVELY THE THRESHOLD THAT YOU'RE GOING TO SEE OF
WHEN WE SAY AN APPLICATION HAS
CROSSED INTO THE TERRITORY OF BAD BEHAVIOR.
SO YOU CAN SEE THE MAJORITY OF APPLICATIONS IN THIS CROSS
SECTION. THESE ARE ALL MAJOR GOOGLE APPS. MOST OF THEM ARE
QUITE GOOD. AND THERE'S A FEW OUTLIERS THAT ARE HAVING ISSUES
WHERE A WAKELOCK IS GETTING STUCK IN THEIR APPLICATIONS.

AND YOU CAN SEE THE PERCENTAGES HERE, THAT THEY LOOK SMALL, BUT WHEN YOU SEE THESE NUMBERS OF,
LIKE, HALF A PERCENT HERE, ONE PERCENT THERE, THOSE ARE JUST
ONE APP. AND AS I MENTIONED BEFORE, ONLY ONE APP NEEDS TO
MAKE THIS MISTAKE FOR YOUR ENTIRE DEVICE TO SUFFER.
MULTIPLE THAT BY THE HUNDRED APPS. IF YOU WORK OUT THE
RATIO, YOU'RE GOING TO HAVE A BAD TIME.
THE NEXT ONE HERE, LET'S TALK ABOUT FOREGROUND CRASHES AND
HELPING OUR DEVELOPERS UNDERSTAND REPEAT OFFENDERS,
RAPID CRASHING IN A CYCLE. WE GENERALLY HAD GOOD
DOCUMENTATION TO UNDERSTAND IF YOU CRASH, BUT NOT REPEATED
CRASHES VERSUS SPORADIC. DO I HAVE A POPULATION OF 5%
CRASHING REALLY EXTREMELY OR DOES IT
SPREAD ACROSS THE POPULATION 95%.
THE VERY LAST ONE HERE IS ABOUT
FROZEN FRAME RATES. YOU CAN SEE
ANOTHER EXAMPLE OF MOST APPLICATIONS ARE ACTUALLY DOING
PRETTY GOOD.

AND IN THIS CASE, THERE WAS ONE WHO WAS A LITTLE
NOT AS GOOD. AND WHEN WE PASSED
THIS DATA ALONG TO THE TEAM, THEY'RE LIKE, CRAP. NOT THEIR
INTENT, OBVIOUSLY. BUT IT REALLY MAKES THE
EXPERIENCE ON THE DEVICE NOT REALLY THAT FANTASTIC.
ESPECIALLY THE APPLICATION. IT MAKES THE USER GO, IS MY DEVICE
WRONG? IS THE APP BAD? WHAT'S HAPPENING?
SO GIVING THIS INFORMATION BACK TO DEVELOPERS, THEY'RE ABLE TO
START REMEDYING THESE PROBLEMS AND SOLVING THEM.
SO THE BIG THING HERE IS VISIBILITY. AND THIS IS
VISIBILITY BOTH FOR YOU GUYS AS WELL AS FOR THE USER ON THEIR
DEVICE. SO NEW DEVELOPER TOOLS, WE'RE
ALSO DOING A LOT OF OUTREACH BOTH INTERNALLY AND EXTERNALLY
WITH BIZDEV, TO REACH OUT TO TEAMS AND INFORM THEM, HEY, DO
YOU KNOW THIS IS HAPPENING ON YOUR APPS? IN MANY CASES WE
DON'T, AND IT'S A QUICK FIX, ESPECIALLY WITH WAKELOCKS.
AND THE LAST ONE HERE IS BATTERY SETTINGS IN THE PLAY
STORE. AND I'LL TALK A LITTLE BIT ABOUT THAT, AND OEM
DASHBOARDS. WE ALSO WANT TO GET
THIS DATA OVER TO OEMs SO THEY CAN SEE WHAT IS GOING ON AND
THEY CAN SEE WHAT DEVICES ARE INTRINSICALLY GOOD AND YOU HAVE
A STRONG BASE TO WORK ON, THAT YOU'RE NOT SEEING JANK BECAUSE
OF THE DEVICE FREAKING OUT, BUT YOU'RE HAVING A GOOD EXPERIENCE
AND THAT YOU HAVE THE ABILITY TO
CONTROL YOUR OWN DESTINY.

SO BATTERY MENU ON HERE IS
ABOUT — THIS IS THE NEW O BATTERY MENU. AND IT WAS
REDESIGNED WITH THE IDEA OF BEING ACTIONABLE FOR USERS. WE
WANTED TO MAKE SURE THAT IF YOU GO TO THIS MENU, YOU DON'T GO,
OKAY, I SEE GOOGLE PLAY SERVICES, THE SETTINGS —
ANDROID OS, AND SCREEN. YOU'RE,
LIKE, WHAT AM I SUPPOSED TO THINK IF I SEE THIS? THERE'S
REALLY NOTHING ACTIONABLE HERE. AND WHILE IT WAS TECHNICALLY
ACCURATE, IT WASN'T NECESSARILY USEFUL TO WHAT YOU'RE TRYING TO
DO, IS TO UNDERSTAND WHAT APPLICATIONS ARE IMPACTING YOUR
BATTERY LIFE. SO THIS IS HOW WE RESTRUCTURED
IT. AND WE ALSO INCLUDED, THOUGH, YOUR FOREGROUND
INTERACTION WITH THOSE APPLICATIONS. AND THIS IS
SOMETHING THAT HAPPENS REALLY QUITE COMMONLY. AND I'LL GIVE
YOU JUST A QUICK AN ANY DOTE FROM INTERNALLY.
I HAD A BUCK FILED TO BUG FILED TO ME, IT WAS ABOUT ANDROID
BATTERY LIFE, IT'S HORRIBLE.

I DON'T MAKE IT PAST 3:00, WHAT'S GOING ON?
WHAT HAPPENED ON THEIR DEVICE WAS THEY WERE PLAYING POKEMON
GO FOR TWO HOURS ON THURSDAY AT
1:00 P.M. AND I WAS — AND MY REPLY WAS,
THAT'S PRETTY AMAZING THAT YOU GOT THIS MUCH BATTERY LIFE OUT
OF POKEMON GO ON YOUR PHONE. ALSO, IT WAS THURSDAY AT 1:00
P.M., GOOGLER. BUT, YOU KNOW, THE THING WAS
THAT I TOOK AWAY WAS, THEY DIDN'T REALIZE THEY PLAYED IT
THAT LONG.

AND SO THAT WAS HAPPENING QUITE OFTEN. YOU'D
SEE AN APP WITH BATTERY DRAIN, BUT YOU DON'T NECESSARILY
RECOGNIZE IT WAS BECAUSE, OH, I USED MY PHONE, LIKE, AN EXTRA
HOUR TODAY. AND IT'S HARD TO REMEMBER, HOW LONG DID I REALLY
HAVE THE SCREEN ON. SO THAT'S HOW WE STRUCTURE BATTERY, IS TO HELP INFORM YOU OF HOW LONG
YOU'RE USING THE DEVICE, HOW LONG YOU'RE USING DIFFERENT
APPLICATIONS, AND SO THAT YOU CAN MAKE THIS COMPARISON OF
WHAT IS HAPPENING IN THE APPS.
WE DON'T WANT TO PASS JUDGMENT ON AN APPLICATION BEING GOOD OR
BAD.

IT'S NOT NECESSARILY A BAD
THING IF AN APP USES 20% OF YOUR
BATTERY. IF YOU WERE LIVE STREAMING AN EVENT, THAT'S
PRETTY DECENT, ESPECIALLY IF IT WAS FOR AN HOUR OR TWO. SO
WE'RE NOT TRYING TO SAY INTRINSICALLY THINGS ARE BAD IF
THEY'RE HIGH. BUT WE WANT TO ADD SOME VISIBILITY SO A USER
CAN SEE THIS IS AN APP I DIDN'T TAKING UP 5% OF MY BATTERY?
AND THOSE QUESTIONS STARTED
HAPPENING ON THE USERS' PART AND
GIVING YOU GUYS FEEDBACK AND YOU CAN SEE THE SAME DATA IN
THE PLAY PLAY CONSOLE.
SO THIS IS WHERE I WILL TRANSITION TO TALKING A LITTLE
BIT ABOUT THE FUTURE, SO YOU CAN
KIND OF GET AN IDEA OF WHERE WE'RE GOING.
THIS IS ALSO MY SUGGESTION TO REALLY LOOK AT BACKGROUND
LIMITS, TO LOOK AT TARGETING O, TO TRANSITIONING AWAY FROM
BACKGROUND SERVICES TO JOBS, ALARMS, GCM, ET CETERA.
AND THE THING IS, WE WANT TO GET
TO THIS AMAZING BATTERY LIFE THAT I STARTED OUT WITH,
MULTI-DAY BATTERY LIFE.

AND TO DO THAT, THERE'S A FEW THINGS
WE'RE GOING TO HAVE TO CHANGE, IF YOU WILL. BUT I WANT TO
TALK ABOUT SOME PRINCIPLES.
ONE IS, WE FUNDAMENTALLY BELIEVE
APPLICATIONS SHOULD BE ABLE TO RUN IN THE BACKGROUND. WE WANT
MUCH MORE WELL-DEFINED RULES ABOUT WHEN APPLICATIONS ARE
ABLE TO RUN.
TODAY, YOU CAN SEE A NUMBER OF OEMs TAKING STRATEGIES, TRYING
TO SOLVE THIS PROBLEM INDEPENDENTLY. AND IT BECOMES
REALLY DIFFICULT FOR DEVELOPERS TO DEAL WITH THAT WORLD WHEN
YOU DON'T NECESSARILY KNOW WHAT THE RULES ARE.

SO WE WANT TO GET A
LOT CHRIS PER THERE. WE ALSO WANT USERS TO BETTER
UNDERSTAND BATTERY IMPACT. YOU CAN ARGUE MY PREVIOUS
STATEMENTS ABOUT THE SETTINGS MENU, WHAT,
THE USER HAS TO DO MATH IN THEIR
HEAD ABOUT HOW MUCH BATTERY IT USED? AND I AGREE WITH YOU
COMPLETELY . WE WANT TO GET TO A BETTER PLACE WHERE IT'S MUCH
EASIER FOR A USER TO UNDERSTAND WHAT'S HAPPENING.
AND WE WANT TO THEN ENABLE A USER WHO SAYS, I'M NOT OKAY
WITH THIS.

AND IF THE APPLES
DOESN'T OFFER THE CONTROL, TO GIVE THEM
ANOTHER OPTION AT UNINSTALLING
THE APPLICATION, SOMETHING OTHER
THAN JUST THE NUCLEAR OPTION. THEN THE LAST ONE IS, WE REALLY
WANT THIS IDEA OF CONSISTENT DEVICE PERFORMANCE, YOU
SHOULDN'T BE WORRYING, WILL MY DEVICE MAKE IT THROUGH THE DAY,
WILL IT BE ABLE TO MAKE IT HOME UNTIL I GET ON THE CHARGER. WE WANT IT TO BE SOMETHING
RELIABLE. ALL THESE USE CASES THAT WE'RE
DOING ON PHONES AND ALL THE PROPERTIES FROM GOOGLE AND ALL
THE PROPERTIES THAT YOU'RE MAKING AS APP DEVELOPERS, YOU
CAN'T REALLY RELY ON THIS STUFF UNLESS YOU KNOW YOUR PHONE'S
GOING TO BE THERE.

AND SO THAT'S REALLY THE UNDERPINNING
FOR THIS GENERAL STRATEGY. AND SO HOW DO WE GET THERE?
SO THERE'S THREE KIND OF BIG TIERS. WE HAVE TO CONSIDER
WHAT IS THE API CONTRACT? WE DON'T
WANT TO BREAK THE PROMISES WE MAKE TO YOU.
HOWEVER, WE DO MAKE A LOT OF PROMISES THAT WE LATER REGRET.
AND SO AN EXAMPLE OF THIS IS A WAKELOCK. IF YOU WERE TO
GENERALLY DESCRIBE A WAKELOCK, YOU'RE SAYING, WE'VE GIVEN THE
APPLICATION — ANY APPLICATION CAN TELL THE OS, STAY AWAKE
UNTIL I SAY TO GO TO SLEEP, INDEFINITELY.

AND WHEN YOU
GIVE THAT LEVEL OF CONTROL AND
THERE'S NOT REALLY A WAY TO CLOSE THE LOOP, YOU END UP WITH
VARYING BATTERY LIFE. SO WE HAVE TO FIGURE OUT, THEN,
WHAT IS THE RIGHT PROMISE TO MAKE TO A DEVELOPER AND WHAT IS
THE RANGE OF THAT PROMISE THAT WE SHOULD BE GIVING TO ENABLE
THE USE CASES BUT MAKE SURE THAT
THE OS CAN BE RESPONSIVE IN THE FACE OF ADVERSITY OR
APPLICATIONS TAKING ADVANTAGE OF
THE PROMISE THAT'S BEING MADE. THE OTHER IS THE ATTRIBUTION I
MENTIONED BEFORE AND THE CONTROLS THAT THE USER CAN TAKE
ADVANTAGE OF THIS STUFF.

TOGETHER, THE THREE OF THESE
THINGS SHOULD GIVE US A MUCH BETTER STRUCTURE.
AND SO THIS IS — ALL OF THIS IS, AGAIN, LIKE YOU SEE THIS
LITTLE EXCITING BADGE ABOUT PENDING REVIEW ON THERE. THESE
ARE REALLY JUST IDEAS TO ARTICULATE HOW WE'RE
APPROACHING THE PROBLEM. BECAUSE WE KNOW
IT'S A BIG CHANGE. AND SO WE'RE
TRYING TO BROADCAST THIS CHANGE ADVANTAGE OF IT. YOU CAN START
MOVING OVER TO BACKGROUND LIMITS
AND TARGETING NODE NOW SO THAT YOU'RE NOT GOING TO HAVE A BAD
TIME LATER ON.

AND SO SOME OF THESE THINGS IS
WE NEED TO LOOK AT MORE LIMITS ON BACKGROUND SCANNING. WE —
WE HAVE TO ADJUST THE LIMITS THAT WE'RE DOING. WE HAVEN'T
REALLY GOTTEN AROUND TO BLUETOOTH YET. WE'RE ALSO
LOOKING AT APPLICATIONS LISTENING TO OTHER EVENTS ON
THE DEVICE AND WHETHER THOSE THINGS SHOULD BE HAPPENING OR NOT.
A BIG ONE HERE IS DEFERRING WORK. WE WANT THE OS TO HAVE
MORE FLEXIBILITY TO HAVE DISCRETION ABOUT WHEN JOBS RUN. WHEN IT'S ALL SERVICES-BASED,
THE OS HAS REALLY NO CONTROL. IF THE SINGLE LARGEST INSTALLED
BASE APPLICATION MAKES A UNILATERAL DECISION TO INCREASE
WAKELOCK TIME, THE OS TODAY AND THE USER IS POWERLESS TO DO
ANYTHING ABOUT IT. SO THAT'S WHY WE'RE LOOKING TO MAKE THESE TRANSITIONS. AND THE BALANCE
SHOULD BE NOW USERS ARE MORE IN THE DRIVER'S SEAT ABOUT WHAT
FEATURES THE APPLICATION'S GIVING AND WHETHER THE USER
FINDS VALUE IN THOSE FEATURES RUNNING IN THE BACKGROUND.

AND
THEN THEY CAN ARTICULATE THAT. THE DEFAULTS FOR ALL OF THESE
THINGS IS ON, AND THE MODEL YOU CAN THINK OF, AS LONG AS YOU'RE
COOL, THE OS IS COOL AND EVERYBODY WILL BE COOL AND IT'S
GREAT . AND IF IN THIS SCENARIO, THOUGH, APPLICATIONS
START GETTING AGGRESSIVE, BATTERY STARTS GETTING HIGH,
SCANNING RATES START GETTING HIGHER, WE MAY START INFORMING
THE USER, HEY, THIS STUFF IS KIND OF HEAVY ON THE BATTERY,
DO YOU WANT IT TO RUN IN THE
BACKGROUND? AND THEN THEY CAN ARTICULATE THAT BACK TO THE OS. AND THEN WE CAN, YOU KNOW,
BEGIN HAVING A CONTROL SURFACE FOR
HOW WE MANAGE INDIVIDUAL
APPLICATIONS. AND SO THEN THE USER CAN SAY, THESE TEN APPS I
CARE ABOUT A LOT. THESE OTHER APPS, NOT SO MUCH. WE'RE NOT
SUGGEST THAT WE NEED TO HAVE A MICRO MANAGING MENU.

THAT'S
NOT THE DESIRE. BUT USING THINGS
LIKE HOW USERS ARE INTERACTING WITH THE APPLICATION, HOW OFTEN
ARE THEY INTERACTING WITH GCM APPLICATIONS WHEN THE IS 101 UP
. HOW OFTEN DO THEY INTERACT WITH — HOW THE OS SHOULD DOLE
OUT ITS LIMITED RESOURCES, NAMELY BATTERY.
THE LAST ONE IS WE HAVE TO BEEF UP THE IDEA OF FOREGROUND
SURFACE — HOW DOES THAT NOT TURN INTO ALL THE APPLICATIONS
RUSHING TO THE EXITS OF FOREGROUND SERVICE AND THEN
WE'RE BACK IN THE SAME MESS THAT
WE ARE NOW WITH NO CONTROL SURFACE AGAIN.
AND WE WANT TO FIND A BALANCE SO THAT APPLICATIONS
CAN GENERALLY DO EVERYTHING THEY NEED AND IN THE
EXTREMES, THE USER IS ABLE TO ARTICULATE APPROVAL FOR THESE
EXTREME SITUATIONS. AND WE'RE HOPING THAT'S GOING TO
RESULT IN A MUCH MORE STABLE, MUCH MORE RELIABLE DEVICE IN
THE LONG RUN. AND SO HOPEFULLY THAT GIVES YOU A
BIT OF INSIGHT ABOUT HOW WE'RE APPROACHING ANDROID
HEALTH AND MOSTLY BATTERY LIFE AND RESOURCE CONTENTION.
SO — OH, I FORGOT A SLIDE. BUT THE IDEA OF THE LAST ONE
WAS ATTRIBUTION AND VALUE. SO WE WANT TO REALLY MAKE
THAT IDENTIFIED, AND I ALREADY TALKED ABOUT THE
POINTS.

I WON'T BORE YOU REPEATING IT.
AND THANK YOU VERY MUCH FOR THE — FOR YOUR TIME.
