Thoughts from Google I/O

Better late than never, but a few weeks ago, I got the chance to attend Google I/O — this time, not just as a fan of the Android platform but representing a developer. Below are some of my key takeaways from the event

  • Google‘s strategic direction – there were three big themes that were emphasized
    • Next Billion – a lot of what Google is doing (like making Google Maps / YouTube work without internet) is around making Chrome/Android/Google Search the platforms of choice for the next billion mobile users — many of whom will come from Brazil, India, China, Indonesia, etc. Its important for us to remember the US/Western Europe is not the totality of the world and that there’s a big chance that future major innovations and platform will come from elsewhere in the world.
    • Machine Learning – I was blown away (and a little creeped out!) by the machine learning tech they showed: Google Now on Tap (you can hold the home button and Android will figure out what’s on your screen/what you’re listening to and give you relevant info), the incredible photo recognition tech in the new Photos app (which you should all try! unlimited storage!), innovations Android is making in unlocking your phone when it knows its been in your pocket and not your desk. Every company should be thinking up where machine intelligence can be used to enhance their products.
    • Everything Connected – it reminded me of Microsoft’s heyday: except instead of Windows everywhere, its now Android/Chrome everywhere: Android Wear, Chromecast, Android TV, Android Auto, Brillo/Weave, Cardboard for VR, Nest/Dropcam for the home, things like Jacquard & Soli enabling new user interfaces, etc.
  • Marketing enhancements to Google Play: Google has taken steps to make application developers’ lives easier — more details here: http://android-developers.blogspot.com/2015/05/empowering-successful-global-businesses.html, but:
    • I sat through a panel on how Google does personalized recommendations / search on Google Play — long story short: keywords + ratings matter
    • Google will now allow A/B testing of Google Play store listings
    • Google Play console now directly integrates App Install advertising so you can run campaigns on Google Search, AdMob, and YouTube
    • Google Play console will also track how users get to Play Store listing by channel and how many convert to install
  • Android M – a lot of tweaks to the core Android app model for developers to pay attention to
    • Permissions: Android M moves to a very iOS-like model where app permissions aren’t granted when you install the app but when the app first uses them; they’ve also moved to a model where users can go into settings and manually revoke previously granted permissions; all Android developers will need to eventually think about how their apps will work if certain permissions are denied (see: http://developer.android.com/preview/features/runtime-permissions.html)
    • App Links: Android will now let apps handle all links on websites they control by default (see: http://developer.android.com/preview/features/app-linking.html)
    • Doze and App Standby: Applications will now have two additional modes that the OS may enforce — one called Doze that keeps all apps in sleep mode to reduce power drain and Standby where the OS determines an app is “idle” and cuts off network access, syncs, and jobs — apps in both modes can still receive “high priority notifications” (see: http://developer.android.com/preview/behavior-changes.html under Power-Saving Optimizations)
    • Auto Backup: Applications will now backup up to 25MB worth of data to the user’s Google Drive (but won’t count against their quota) once every 24 hours; this can be customized (see: http://developer.android.com/preview/backup/index.html)
    • Fingerprint API, Direct Share, and Voice Interactions: universal fingerprint rec API + ability to share specific content with specific favorite users (i.e. send to someone over Facebook Messenger, etc) + new way to build voice interactions in app (see: http://developer.android.com/preview/api-overview.html, starting from Authentication)
  • Other stuff for developers
    • App InvitesGoogle has built out custom share cards / install flows and deep links to make it easier for users to share apps with their friends: http://googledevelopers.blogspot.com/2015/05/grow-your-app-installs-with-app-invites.html
    • Android Design Library: Google now has libraries to help devs build out Material Design elements — now, you too, can make your own Floating Action Button!: http://android-developers.blogspot.com/2015/05/android-design-support-library.html
    • Chrome Custom Tabs: basically lets you embed Chrome in your app with custom styling (rather than having to embed a vanilla webview and do a lot of work styling it), its apparently already out in beta channels for Chrome: https://developer.chrome.com/multidevice/android/customtabs
    • Google Cloud Testing Lab: This was pretty cool (and a product of Google’s acquisition of Appurify). Now, Google will provide two highly useful testing services for Android developers: (more details: https://developers.google.com/cloud-test-lab/)
      • For free/automatically: pound on every button / interface on your app that they can see after launch for 1 min and see how many crashes they can get on a variety of Android devices (which helps given the sheer number of them that exist)
      • Paid: run custom Espresso or Robotium tests on specific devices (so you can get test coverage on a broader range of devices doing a specific set of things)
    • Places API: a lot of talks promoting their new mobile Places APIs (which will let iOS and Android apps have better mapping and place search capability)
    • Google Cloud Messaging: this is basically Google’s push notification delivery engine and they announced support for iOS as well as “Topics” (so devices don’t have to get every notification, just the ones relevant to them): http://android-developers.blogspot.com/2015/05/a-closer-look-at-googleplay-services-75.html
    • Espresso testing framework: this was a ridiculously packed session — but Google has apparently made numerous refinements to the Espresso UI testing framework
  • A lot of cool announcements about new Android Wear functionality (which my Moto 360 is eagerly awaiting)
  • Just cool shit from ATAP
