Android Developers Backstage

Raluca Sauciuc joins Tor and Romain to talk about what goes on behind the scenes in Android Studio. Raluca takes us through the tools and workflows used by the Android Studio team to improve performance and memory usage, and avoid future regressions. She also explains how the team adopts new versions of the IntelliJ IDE and platform, and how they can deal with massive code merges.

This time, Tor, Romain, and Chet were joined by Siyamed Sinir and Sean McQuillan from the Android Text team to talk about, well, text. Which, it turns out, is a very deep, complicated, and constantly evolving technology. The conversation covered everything from the fundamentals of the text stack on Android to the capabilities and implementation of text in Jetpack Compose to internationalization to fonts to emojis to performance to.... you get the idea. There was a lot of stuff to talk about. And so much subtext.

We recorded episode 191 from the studio in the London office, where Rebecca Franks from the developer relations team joined Chet as a guest host. We talked with Andrei Shikov, Matvei Malkov, and Andrey Kulikov from the Jetpack Compose engineering team about layouts, especially the lazy ones, which are the Compose equivalent of RecyclerView. Rebecca, Chet, Andrei, Andrey, and Matvei, in the London recording studio.   Links: Layouts in Compose Compose Custom layouts ADB 167: Jetpack Compose Layout   Chet: @chethaase Romain: @romainguy Tor: @tornorbye Rebecca Franks: @riggaroo Andrei Shikov: @shikasd_ Matvei Malkov: @matvei_jj Andrey Kulikov: @and_kulikov

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.
