In this episode Nick and Chet are joined by Dois Liu and Nader Jawad to discuss Compose's Animation and Graphics systems. They cover their goals to make both systems easier to understand, more consistent and simpler to work with. They explain how they adapted traditionally imperative systems to a declarative world and give an overview of both the high level composables the library offers as well as lower level building blocks you can drop down to for more control.

Hosts Chet & Nick speak to Doris and Nader.

In this episode, Romain and Tor are joined by Adarsh Fernando, Arif Sukoco and Yahan Zhou from the Android Studio team, covering the recent improvements to support for testing. 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.

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, Chad and Jeff from the Android Security team join Tor and Romain to talk about… security. Chad and Jeff explain what the platform does to help preserve user trust and device integrity, why it sometimes means restricting existing APIs, and touch on what apps can do or should worry about.

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.

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.

In this episode, we talk with Nat Duca and Sumir Kataria from the Android graphics team about the graphics stack -- covering shaders, GPUs, Vulkan, OpenGL, ANGLE, drivers, blur, pixels and of course Chet's favorite topic; colors.

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.
