Android Developers Backstage

Kweku, Makoto, Amith, Chet, Romain, and Tor In this episode, Chet talked with Amith Yamasani, Makoto Onuki, and Kweku Adams from the framework team about power management. We waxed poetic about the heuristics the system uses to kill tasks, doze mode and how the system tries to save battery, TrimMemory requests, JobScheduler (the underlying platform facility used by WorkManager), AppStandby buckets, and more.

Mike, Romain, Yigit, and Chet In this episode, Chet and Romain talk with Yigit Boyar, from the Jetpack team, and Mike Nakhimovich from Dropbox. Mike and Yigit have been working on an Open Source library called Store. Store helps with the fetching, caching, storing and sharing of data in your application. Both Yigit and Mike used this opportunity to teach Chet and Romain about the repository pattern, how Store works, what makes building a library like Store challenging and much more.

Adam, Romain, Tor, and Chet, on location in the fancy and totally upscale ADB recording studio In this episode, Tor, Romain, and Chet talk with Adam Powell from the UI Toolkit team about Jetpack Compose. The conversation meandered into declarative programming, reacting to state changes, data flowing through an application, and Kotlin domain-specific languages.

Tor, Nicolas, John, Romain and Chet in the Android Studio In this episode, Tor, Romain and Chet chit chat with Nicolas Roard and John Hoford from the Android Studio team about Motion Layout -- and ConstraintLayout and visual editing in the IDE. In the recording session they also promised to release ConstraintLayout 2.0 beta 4 before the podcast was released. And they achieved that: https://androidstudio.googleblog.com/2019/12/constraintlayout-200-beta-4.html. Subscribe to the podcast feed or download the audio file directly.

Michael, Chet and Romain in the cozy London recording studio. In this episode, Chet and Romain travel all the way to London to have a chat with Michael Wright. This is not Michael's first time on the podcast and one again the discussion is about displays, input devices and haptics. If you want to learn more about high refresh rate displays (90/120 Hz), HDR, audio-coupled haptics, how gamepads are supported and, curiously, about the Android API council, you found the right episode!

We forgot to take a picture of ourselves when we recorded this. Please use your imagination. In this episode, Chet and Florina Muntenescu (from the Android Developer Relations team) talk with Dom Elliott from the Google Play team about Android App Bundles and other Google Play features. App bundles are the new packaging format for Android apps. They allow you to upload a single version of your app, then Google Play can distribute optimized versions of that app to users, depending on device-specific capabilities, like the selected locale(s) on the device. We also talked about other recent Google Play features (related to bundles and not), such as on-demand delivery and in-app updates. Subscribe to the podcast feed or download the audio file directly.

Tor, Jerome, Chris and Xavier in the recording studio. In this episode, Tor chats with Jerome Dochez, Chris Warrington and Xavier Ducrohet from the Android Studio build system team. We discuss a lot of topics -- the new speed attribution feature in 4.0, the effort to create new APIs for plugin authors, and a lot more.

Allen, Chris, Adam, part of Tor, Dan (taking the photo), and Chet. All of them are also in the monitor, but backwards. Oh, and note the gym sock being used to dampen noise on the mic. High tech stuff, ADB. In this episode, Chet and Tor talk with Chris Banes, Adam Cohen, Dan Sandler, and Allen Huang about Gesture Navigation. Gesture Nav is an important UI behavior change in the Android 10 release that developers should handle and test. Chris has written Gesture Nav articles recently. This conversation goes further into the background and reasons for the change, as well as techniques for dealing with it. Note: The audio in this episode, is not up to the usual quality bar. We had the choice between recording the conversation with a non-ideal setup or not doing it at all. We chose content over quality. Subscribe to the podcast feed or download the audio file directly.

Chet, Tor, Romain, Cyril and Zarah, laughing at something stupid funny that Chet said. Amongst the many talks and announcements at the Android Dev Summit 2019 was a hidden gem: the first ever live episode of this podcast! Chet, Romain and Tor took this opportunity to have a chat with Zarah Dominguez and Cyril Mottier. Both Zarah and Cyril work as Android app developers and are known for their presentations at various Android conferences. We talked about modernizing large codebases, Kotlin, data binding, themes & styles, and many other things. Let's not spoil the podcast here.

Chet, Glen, Rod, and Tor. Il n'y a pas de Romain. In this episode, Chet and Tor talk with Rod Graves and Glen Murphy from the Android UX team. We talked about various UX changes in Android over the years, as well as UI design in general. For example, Glen compared UX design to API design; trying to provide an interface for the users of your product that helps them build a mental model to better understand how everything fits and works together.
