In this episode, Tor and Romain chat with Greg Baker and Joe Baker-Malone about exciting new Android Studio features made possible by Firebase integration. Physical device streaming allows you to connect remotely to physical devices hosted in Google's secure data centers and use them for all your development needs. We also explore other time saving features like the ability to go from a crash report directly to the correct line of code, even across git branches.

In this episode, Chet and Romain speak with Ken Russell and Corentin Wallez from the WebGPU team. WebGPU is a new API that brings modern GPU rendering and compute functionality to web and other platforms (including Android!). We talk about the genesis and capabilities of WebGPU, WGSL (WebGPU's new shading language), the state of WebGL (the predecessor API for web GPU rendering), and lots of other fun related graphics topics.

This time, Romain, Tor, and Chet talk with Leland Richardson, George Mount, and Chuck Jazdzewski from the Jetpack Compose team about performance. The team has been looking at performance issues recently and discusses what they've found, what gotchas lie in wait for library developers, what tools and compilers can magically handle for you... and what they can't. Tune in to learn about why we worry about autoboxing (and why you probably shouldn't).

You saw it at Google I/O - now you can hear about it in the comfort of your own headphones! Tor, Romain, and Chet talk with Siva Velusamy and Sandhya Mohan from the Android Studio team about the just-launched Studio Bot. This new AI-powered assistant enables conversational queries in the IDE to help with coding, commenting, confusion, or if you just need a friend.

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.
