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.

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.   Brian, Romain DerekChet, Tor   Links: Skia's SkSL/AGSL playground & debugger → https://goo.gle/3DHFJYm  Skia's SkSL documentation → https://goo.gle/3uZK0CA    Brian: @BrianOsman Chet: @chethaase Romain: @romainguy Tor: @tornorbye

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.
