Android Developers Backstage

It's history time! Or even [pre-]ART History time! We didn't take a picture this time. Please imagine what we looked like. This time, Tor, Romain, and Chet were joined by Dan Bornstein, one of the early members of the Android team. Dan joined in 2005 to create a runtime for Android, which became Dalvik. We talked about some of the early placeholder VMs used while Dalvik was coming online, some of the design decisions for Dalvik (like its register-based vs. stack-based implementation), and nice techy details about runtimes, garbage collectors, and optimizations.

“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.

Chet, Iliyan and Tor in the Studio In this episode, Chet and Tor chat with Iliyan Malchev from Project Treble. We already covered this a year and a half ago back in episode 75, but this time we dig deeper and also cover the progress made since then.

Michael, Tor (not pictured), Romain (not pictured), and Chet (not even present). Some podcasts are conversations. Some are more like interrogations in a café. In this episode, Tor and Chet Romain talked with Michael Wright from the Android Framework team. Michael works on input, display, power manager, and haptics, which are, by amazing coincidence, exactly what they talked about. Subscribe to the podcast feed or download the audio file directly.

Romain, Philip, Ben, Tor, and Chet (listed in alphabetical order) In this episode, Chet, Romain and Tor talk to Philip Simpson and Ben Trengrove from the cast of Pocket Casts. We talk about their app, coincidentally called "Pocket Casts," and how they implemented various features like Material, audio, and even how the company made a complicated weather app for a country where it's always sunny. Oh, and we talked about some of the stuff happening at Google I/O 2019, because that's when we recorded this conversation. Subscribe to the podcast feed or download the audio file directly. Links:
