In this episode, Tor and Chet learn some more about performance from Carmen. Carmen works on the Android Platform Performance team and is an expert on everything related to performance. This is the perfect episode for you if you ever wanted to learn more about R8, perfetto, baseline profiles, custom performance tracing, power metrics, etc. Tor, Carmen, and Chet Links: Perfetto Android's guide to app performance Baseline profiles Benchmarking with Microbenchmark and Macrobenchmark Jetpack Tracing library Jetpack JankStats library Chet: @chethaase Romain: @romainguy Tor: @tornorbye Subscribe to Android Developers YouTube → https://goo.gle/AndroidDevs

In this episode (the first in-studio-with-guests recording since early 2020!), Tor and Chet spoke with Marc Bächinger, Toni Heidenreich, and Andrew Lewis from the Android Media team, where they work on video technologies and APIs like ExoPlayer. We talked about the evolution of ExoPlayer and platform media capabilities as well as ongoing and near-future features.

It's our first episode back in the studio, and in a new, shiny studio too! In this episode, we talk about some of our favorite new features and changes of the new version of Android, both for users and developers. More importantly, the audio quality of this episode is much better thanks to the amazing work from the media production teams at Google.

"Our job isn't to remove complexity, but to manage it"- Glen Murphy (as remembered by Dan) In this episode, we talk with Dan Sandler and Adam Cohen from the SystemUI team. We dip into a bit of history, talking about where things were at when they joined the team (2009-10), and how things have developed in the many years since, including how these projects and teams scaled from a single person working on it part-time to now having much larger teams doing many more things. Which kind of describes software development in general. We also talk about how to expose (or not) gestures and features in a UI system. Related: there are some bonus pro-tips on using some hidden features of System UI, as a prize for careful listeners and podcast hosts.

Jon and Andrew from the Play team discuss the major refactoring of the Play Store app, including the adoption of Jetpack Compose. They highlight the improvements made to architecture, network fetching, UI rendering, and data storage. The podcast also covers tech debt issues, adoption of Kotlin and MVVM architecture, handling accessibility challenges, app performance improvements, and considerations in migrating code.

In this episode we chat with Derek and Brian from the Skia team about Skia, pixel shaders, and the new "AGSL" API that lets you provide pixel shaders for advanced graphics effects, which was recently added to the preview release of Android T. If you're interested in graphics technology, this is the episode for you. If you're not interested in graphics... you should be.

In this episode we chat with Rahul and Leland from the Android toolkit team about "baseline profiles", a new mechanism which lets applications ship with profiling metadata used at application install time to make it start faster. We discuss how this is used in Jetpack Compose, cloud profiles in general, and more.

In this episode, Clara (Android Toolkit), Florina (Android Developer Relations), and Daniel (Android Product Management) join your usual hosts to talk about large screens, what they are and what they mean for app developers. You will also learn about the resources at your disposal to build high quality experiences on large screen devices: from samples and guidance to canonical layouts and new APIs such as window size classes Romain, Clara, Florina, Daniel, Chet, and Tor Links: Large screens documentation Material adaptive design docs ADS talk: Build Android UIs for any screen size Codelab: Support foldable and dual-screen devices with Jetpack WindowManager Samples Jetnews: Responsive UI implementation with Compose Jetcaster: Tabletop support implementation with Compose Google I/O Android App: Responsive UI implementation with Views Trackr: Responsive UI implementation with Views Clara: @clarabayarri Daniel: @pmatgoog Florina: @FMuntenescu Chet: @chethaase Romain: @romainguy Tor: @tornorbye

In this episode, we chat with Yigit Boyar (again!) from the Android Toolkit Team and Manuel Vivo from the Developer Relations team about application architecture. The team has released new architecture guidance, and we talk about that guidance here, as well as how our architecture recommendations apply in the new Jetpack Compose world. Yigit, Tor, Manuel, and Chet. Romain was AWOL. Check out the revamped and enhanced Guide to app architecture.
