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.

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.

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.

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. Links: ADB Live on YouTube

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. Favorite acronym: "WTFY"

In this episode, Chet and Romain talk about talking, speak about speaking, monologue monologuing. We have a conversation about various aspects of giving presentations. Everyone has their own style and techniques, and there are no right answers for giving talks that audiences enjoy. But we all have opinions and techniques that work for us; here are some of ours. We talk about making presentations more engaging, having co-speakers, picking topics, getting practice and experience, choosing events, and all kinds of other random stuff that came up in the conversation.

In this episode, we chat with Chris Craik and Dustin Lam from the AndroidX team about benchmarking. We cover the new AndroidX benchmarking library, how to use it, and what problems it solves. If you're wondering why Chet totally took over the interview towards the end, it's not that he wouldn't share the stage; Romain and Tor had to leave early and snuck out quietly.

Chet and Romain spoke with Anna Goldie from the Google Brain team about machine learning. If you ever wondered what the difference is between AI and machine learning or what deep neural networks are, then this episode is for you. To be clear, this show has nothing to do with Android, we just thought it would be an interesting topic.

Tor and Romain spoke with Andrey Breslav, the lead language designer at Jetbrains for Kotlin. They talked about coroutines, flow, performance, islands near St. Petersburg, evolution of the language, and many other Kotlin-y things. Links: * kotlinlang.org * Develop Android Apps with Kotlin

In this episode, Chet and Romain chat with Carlos Valdivia and Sandra Kwan from the Android Identity and Authentication team, covering related topics like authentication, ID, autofill, backup and restore, and more.

Coroutines are Kotlin's approach to asynchronous programming and they are making their way into various Jetpack libraries. In this episode Tor, Chet and Romain have a chat with Sean McQuillan from DevRel and Yigit Boyar from the Jetpack team to discuss what coroutines are, what problems do they solve and how to use them.

Tor and Chet talked with Vinit Modi and James Fung from the CameraX team. CameraX is a Jetpack support library that released in alpha form at Google I/O 2019. It offers developers an easier way to embed camera functionality while performing more consistently across Android versions (back to Lollipop) and across various devices.

Jetpack Compose is an unbundled UI toolkit written in Kotlin and based on the reactive programming model that was recently introduced at Google I/O. Compose is not ready for production yet but is now being developed in the open on AOSP. In this episode Tor and Romain have a chat with Chuck and Leland to discuss how Jetpack Compose works and some of the goals and ideas behind its design.

In this episode, Chet, Romain and Tor talk to Philip Simpson and Ben Trengrove from the cast of Pocket Casts. We talk about their app, coincidentally called "Pocket Casts," and how they implemented various features like Material, audio, and even how the company made a complicated weather app for a country where it's always sunny. Oh, and we talked about some of the stuff happening at Google I/O 2019, because that's when we recorded this conversation. Links: * Pocket Casts on Google Play
