This includes automated test snapshots, where the emulator captures a snapshot for a failing test you can then load and analyze later, it includes the Test Matrix tool where the IDE shows a matrix of tests and the devices they're running on, as well as a unified Gradle test runner, and Gradle managed virtual devices, and more.   Android Studio Bumblebee: Android Testing   Adarsh Fernando Arif Sukoco Yahan Zhou Romain: @romainguy Tor: @tornorbye

In our ongoing mini-series on Jetpack Compose, Nick and Romain talk to Clara Bayarri and Matvei Malkov about Compose’s support for Material Design. They discuss how Compose supports Material Components and Material Theming out of the box, how you can customize these to your needs or how Compose makes it easier to build your own design system. They also share insights into building reusable components with slot APIs and when to use CompositionLocals and look to the future with Compose’s planned support for Material You.

In this second episode of our mini-series on Jetpack Compose (AD/BC) Nick and Romain are joined by Anastasia Soboleva, George Mount and Mihai Popa to talk about Compose’s layout system. They explain how the Compose layout model works and its benefits, introduce common layout composables, discuss how writing your own layout is far simpler than Views and how you can even animate layout.

In this episode, Chet and Romain welcome Hunter and Nick from the Material Design team. Material Design was originally introduced when Android 5.0 came out and has come a long way since then. Our guests will give you an overview of some of the recent additions and improvements to the Material Design Component libraries: transitions, motion theming, Compose, large screens support and guidance, etc.   Material Design website Material You What’s new with Material at I/O Material Design Components for Android Material Motion with MDC   Hunter: @hunter_stich Nick: @ricknout Chet: @chethaase Romain: @romainguy

This episode is the first in the new mini-series “ADBC” on Jetpack Compose, hosted by Nick Butcher, in which we will dive deep into different topics in Android’s future UI toolkit. This time, Nick and Chet talked with Adam Powell and Leland Richardson about the Compose compiler, the runtime, data flow, and that nifty feature where Compose knows when to call your Composable based on changes in data state.   Also check out: Thinking in Compose Compose State Guide Compose State Codelab Lifecycle of composables Side-effects in Compose Compose Learning Pathway   Adam: @adamwp Leland: @intelligibabble Nick: @crafty Chet: @chethaase Romain: @romainguy Tor: @tornorbye

Cowardly abandoned by Chet and Romain, Tor faces three guests alone. Jeffrey van Gogh, Ting-Yuan Huang, and Yigit Boyar join Tor to talk about Kotlin Symbol Processing (KSP), a new, faster, and better tool to replace annotation processors. You will learn how KSP works, what it can do, why it was created, and how it is used in the Room Jetpack library.

This time, Tor, Chet, and Romain talked with Rohit Sathyanarayana and Florina Muntenescu about the DataStore library. DataStore is the replacement for SharedPreferences, being better for many reasons (it's asynchronous and avoids blocking the UI thread, it is type-safe). It not only has a similar/simple key-value pair API like SharedPreferences, but also has more powerful API as well. It's currently in alpha, but look for it to be the recommended approach soon as it approaches stable.

Chet, Nick, Clara, Leland, Tor, Adam, and Romain. So many guests! This time, Tor, Romain, and Chet chatted with a few people on the Jetpack Compose team, about... Jetpack Compose! Compose hit Beta a couple of weeks ago (don't believe me? Check out the recent Android show on Compose Show!), so we took the opportunity to talk to some of the people that have helped build it. We talk about the current state of the library, but also about some of the design decisions that went into developing the APIs and functionality. (Note on the audio quality for this episode - it turns out that mixing so many people, all of whom recorded themselves separately using very different hardware and setups was... tricky. It's listenable, but maybe a tad below the level we shoot for. Blame the pandemic. I do.)

It's history time! Or even [pre-]ART History time! We didn't take a picture this time. Please imagine what we looked like. This time, Tor, Romain, and Chet were joined by Dan Bornstein, one of the early members of the Android team. Dan joined in 2005 to create a runtime for Android, which became Dalvik. We talked about some of the early placeholder VMs used while Dalvik was coming online, some of the design decisions for Dalvik (like its register-based vs. stack-based implementation), and nice techy details about runtimes, garbage collectors, and optimizations.

In this episode, Tor, Chet, and Romain go over everything that happened in 2020, both good and bad.

Romain, Tor, and Chet talked with Jesse Wilson from Square. Jesse has worked on several popular open-source libraries, including OkHttp, Okio, and [Ok]Moshi. We talk about those libraries, and others, and about Android, library, framework and Kotlin development. And about that nasty habit some engineers have of turning a feature request or minor annoyance into a project of creating a new open-source library instead.

Chet, Dustin, Chris, and Romain. (Tor not pictured. Because he wasn't there) Romain and Chet talked with Dustin Lam and Chris Craik from the Toolkit team about Paging3. Paging3 (currently in alpha) is a complete rewrite of (wait for it...) Paging2, using Kotlin, coroutines, and Flow for optimal implementation and APIs. (But note that there are also APIs for developers using the Java programming language and/or RxJava, so take your pick). We talk about Paging, the asynchronous work that made coroutines an obvious choice for the implementation, recent and future features, and API design in general.

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.

Chet and Romain, featuring a complete lack of Tor. 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.
