This time, Tor, Chet, and Romain talked with Rohit Sathyanarayana and Florina Muntenescu about the DataStore library. DataStore is the replacement for SharedPreferences, being better for many reasons (it's asynchronous and avoids blocking the UI thread, it is type-safe). It not only has a similar/simple key-value pair API like SharedPreferences, but also has more powerful API as well. It's currently in alpha, but look for it to be the recommended approach soon as it approaches stable.

Chet, Nick, Clara, Leland, Tor, Adam, and Romain. So many guests! This time, Tor, Romain, and Chet chatted with a few people on the Jetpack Compose team, about... Jetpack Compose! Compose hit Beta a couple of weeks ago (don't believe me? Check out the recent Android show on Compose Show!), so we took the opportunity to talk to some of the people that have helped build it. We talk about the current state of the library, but also about some of the design decisions that went into developing the APIs and functionality. (Note on the audio quality for this episode - it turns out that mixing so many people, all of whom recorded themselves separately using very different hardware and setups was... tricky.

We look back at how conferences have been impacted by the pandemic, why Android Studio changed its versioning scheme, the new tools and libraries that were released, etc. We would like to thank all of our listeners for their continued support. We'll be back in early 2021 with more episodes and new guests! Subscribe to the podcast feed or download the audio file directly.

Romain, Tor, and Chet talked with Jesse Wilson from Square. Jesse has worked on several popular open-source libraries, including OkHttp, Okio, and [Ok]Moshi. We talk about those libraries, and others, and about Android, library, framework and Kotlin development. And about that nasty habit some engineers have of turning a feature request or minor annoyance into a project of creating a new open-source library instead. Favorite quote, from Jesse: "I started with 2k. Someone told me 8k was faster." Subscribe to the podcast feed or download the audio file directly.

Chet, Dustin, Chris, and Romain. (Tor not pictured. Because he wasn't there) Romain and Chet talked with Dustin Lam and Chris Craik from the Toolkit team about Paging3. Paging3 (currently in alpha) is a complete rewrite of (wait for it...) Paging2, using Kotlin, coroutines, and Flow for optimal implementation and APIs. (But note that there are also APIs for developers using the Java programming language and/or RxJava, so take your pick). We talk about Paging, the asynchronous work that made coroutines an obvious choice for the implementation, recent and future features, and API design in general.

Tor, Don, Chet, and Phil, on a video conference on Tor's machine. VCs are critical to mitigating (but not actually solving) latency issues with remote podcasts. In this first ever full-remote episode, Tor and Chet discuss audio programming with Don Turner from the Android DevRel team, and Phil Burk from the Android Audio Framework team. They chat about Oboe, low-latency audio, audio performance in general, etc. And because Don and Phil know everything about audio, more time was spent before the recording discussing how to properly record the episode than was spent actually recording the episode.

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.

Tor, Romain, Sumir, Ian, and Chet pose for a candid picture far from the recording studio, when they finally realized  they'd forgotten to take a picture in the studio earlier. You'd think they'd have this process nailed by now,  wouldn't you? I mean, 106 episodes; it's not like it's new and all. Honestly, what level of professionalism are we paying for here with this free service? Romain and Chet talk with Sumir Kataria and Ian Lake about the latest developments in the new WorkManager and Navigation architecture components. WorkManager is now in beta and Navigation should be in beta Real Soon Now. Alpha? Beta? Are these all Greek to you?

In this episode, Chet and Tor Yigit Boyar talk again with Chris Craik from the Android Toolkit team about RecyclerView prefetch and the new Paging library. This is Part 2 of a much longer conversation that started in Episode 100, in which Chris talked about Android's UI hardware renderer.

In this episode, Chet and Tor Yigit Boyar talk with Chris Craik from the Android Toolkit team about graphics and the evolution of the UI renderer on Android. By the way, THIS IS EPISODE 100, PEOPLE! WE MADE IT! AND THEY HAVEN'T EVEN CANCELED US YET! Sure, it's because the people that could and would cancel us don't know we exist, but I still think it's an important milestone to still be here, still recording, still posting, and still talking about random Android development stuff. In the studio, we had a massive celebration for this amazing achievement, which consisted of recording the conversation and then returning to the office. (This is actually part 1 of a 2-part episode; we talked so much about rendering that we made the first part into its own episode.

Tor, Sumir, Tor, Chet, a spiral notebook (blank), and Tor In this episode, Chet and Tor talk with Sumir Kataria about the new WorkManager library that was announced at Google I/O (and released in early form). WorkManager makes it easier to schedule asynchronous work at a more appropriate time using a fluent, chainable API. Think of it as JobScheduler (in fact it uses JobScheduler internally when present), but handling situations and devices that don't have a recent enough version of the OS to have the JobScheduler API available.

Chet and Fake Tor* are joined in this podcast episode by Chris Banes, an engineer in the Android Developer Relations group. Chris works on the AppCompat library, and other elements of the Android support library such as the new Palette utility, and talks about those things. And other things. Oh, and we talk about "Shimming around a widget," which is a great phrase if nothing else. * Tor was not available for this recording. He was probably elsewhere, writing code. The part of Tor will be played in this evening's performance by Richard Hyndman (not pronounced "Hindman," of course. Everyone knows that), also from the Android Developer Relations group.

Tor and Chet may not know ART, but they know what they like. In this episode, the first in a two-pART series, they talk with Anwar Ghuloum from the ART, or Android Runtime team.
