The ADB podcast has moved to Libsyn

 Hey ADB listeners!

After nearly 7.5 years and 158 episodes since that first one on KitKat, we've decided to relocate our show notes and feed to Libsyn.

This should give us great distribution (including landing on Spotify, which some of you have asked for), while not sacrificing anything we get from blogger (show notes, the feed, mp3 downloads, the sometimes-awkward pictures of hosts and guests... i
t'll all be there).

This change should have zero visible impact on you. You should not need to subscribe to a new feed to get ADB; it should update automatically and you'll get the new episodes from the new location.

So if you want the show notes for ADB 159, or any of our future episodes, head over to adbackstage.libsyn.com, the new address for your favorite (and only!) Android Developers Backstage podcast content.

And keep listening... because we'll keep talking.

Episode 158: Jetpack Compose... C'est bêta !

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. It's listenable, but maybe a tad below the level we shoot for. Blame the pandemic. I do.)

Thanks to our audio engineer, Dustin Elm, who has handled all of our audio mixing
for the last couple of years, including the tricky part of mixing all of our remote-
recorded episodes, like this one.
Dustin's moving on to (greener? softer? louder?) pastures, so we'll be using
a new, exciting process for mixing future episodes. Thanks, Dustin!

Episode 157: Audio feedback

What does a podcast look like? We don't know,
so here's a picture of the podcast's website

We want to hear from you! In this episode,

Tor, Romain, and Chet talk about what they could do — or not do —to improve Android Developers Backstage.

Please check our survey and let us know how you would like to see this podcast evolve. We recommend you first listen to the podcast to get the full context for some of the questions in the survey.

Episode 156: Android Runtime Classic (Dalvik)

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.

Episode 154: It's a Wrap!

This episode is dedicated to the memory of our dear friend and colleague, Carl Quinn.

Our last episode of the year arrives just in time for the holiday season. In this episode, Tor, Chet, and Romain go over everything that happened in 2020, both good and bad. 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!

Episode 153: Ok, Ok, Ok

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."

Episode 152: Image Loading with Coil

Chet, Colin, Romain, and Tor

This week, Tor, Romain and Chet are joined by a special guest: Colin White from Instacart.

Colin is the author of Coil, a popular image loading library backed by Kotlin and Kotlin Coroutines. In this episode, Colin explains what Coil is, how and why it was created, etc.

Episode 151: Paging3

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.

Episode 145: Grab that Dagger by the Hilt

Eric, Dany, and Romain. Chet not represented to hide the
confused look he had on his face during the entire recording.

We're injecting dependencies! In this episode, Chet and Romain are joined by Daniel Santiago from Jetpack, and Eric Chang from Dagger to talk about Hilt. Hilt builds on Dagger for form Android's new recommended way to perform dependency injection. And it's also a great opportunity for Chet and Romain to display their lack of knowledge in that space.
