Android Developers Backstage

Tor, Romain, Robert, and Chet. Note the winter coat; the temperatures in California had plummeted that week all the way down into the lower 60s (F). Brrrr! Tor, Romain, and Chet talk with Robert Greenwalt from the Android Telephony team about how the phone actually works. And text. And data. And SIM cards. And carrier networks. It turns out that communication is kind of a important feature for phones Subscribe to the podcast feed or download the audio file directly.

Tor and Romain working hard in the studio while Chet enjoyed the scenery in Monterey Our guest-scheduling failed a second time in a row, but on the heels of the Android Dev Summit we had a lot to talk about!

Tor, Romain, and Chet, caught in a totally candid and unexpected photo while working hard in the recording studio. Tor and Romain and Chet completely failed to get a guest for this show. But fortunately, there was a bunch of stuff happening that they talked about instead. KotlinConf, GDG DevFest Ukraine, Droidcon UK, garbage collection, tech talks, comedy talks, Android Studio releases, new Pixel phones, photography, selfies, and more.

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. We created this second episode from that single, larger conversation because the topics are very different and because we just talked too darned long to stuff it all into a single episode.

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. We will carry on into non-rendering topics in the next Chris-filled episode.) Subscribe to the podcast feed or download the audio file directly. Links:

In this episode, Chet and Tor talk talks with Patrick Robertson from the Location team about... location! We wax poetic about fine-grained location using Wifi routers (among other mechanisms), the Fused Location Provider API for apps that need location information, battery impact of location (and what we're doing to improve that), how GPS works (apparently it uses pieces of string!), and detecting 3D locations for finding where you are in a tall building.
