Chet, Tor, Romain, Cyril and Zarah, laughing at something stupid funny that Chet said. Amongst the many talks and announcements at the Android Dev Summit 2019 was a hidden gem: the first ever live episode of this podcast! Chet, Romain and Tor took this opportunity to have a chat with Zarah Dominguez and Cyril Mottier. Both Zarah and Cyril work as Android app developers and are known for their presentations at various Android conferences. We talked about modernizing large codebases, Kotlin, data binding, themes & styles, and many other things. Let's not spoil the podcast here.

Chet, Glen, Rod, and Tor. Il n'y a pas de Romain.  In this episode, Chet and Tor talk with Rod Graves and Glen Murphy from the Android UX team. We talked about various UX changes in Android over the years, as well as UI design in general. For example, Glen compared UX design to API design; trying to provide an interface for the users of your product that helps them build a mental model to better understand how everything fits and works together.

Chet and Romain, featuring a complete lack of Tor. In this episode, Chet and Romain talk about talking, speak about speaking, monologue monologuing. We have a conversation about various aspects of giving presentations. Everyone has their own style and techniques, and there are no right answers for giving talks that audiences enjoy. But we all have opinions and techniques that work for us; here are some of ours. We talk about making presentations more engaging, having co-speakers, picking topics, getting practice and experience, choosing events, and all kinds of other random stuff that came up in the conversation.

Chet, Dustin and Chris In this episode, we chat with Chris Craik and Dustin Lam from the AndroidX team about benchmarking. We cover the new AndroidX benchmarking library, how to use it, and what problems it solves. If you're wondering why Chet totally took over the interview towards the end, it's not that he wouldn't share the stage; Romain and Tor had to leave early and snuck out quietly.

Romain, Anna, and (unfortunately) Chet Chet and Romain spoke with Anna Goldie from the Google Brain team about machine learning. If you ever wondered what the difference is between AI and machine learning or what deep neural networks are, then this episode is for you. To be clear, this show has nothing to do with Android, we just thought it would be an interesting topic. Subscribe to the podcast feed or download the audio file directly. Links:

Tor, Yigit, Sean, Romain and Chet doing their (co)routine. Coroutines are Kotlin's approach to asynchronous programming and they are making their way into various Jetpack libraries. In this episode Tor, Chet and Romain have a chat with Sean McQuillan from DevRel and Yigit Boyar from the Jetpack team to discuss what coroutines are, what problems do they solve and how to use them.

Chet, James, Vinit, and Tor, in reverse-polish notation. Tor and Chet talked with Vinit Modi and James Fung from the CameraX team. CameraX is a Jetpack support library that released in alpha form at Google I/O 2019. It offers developers an easier way to embed camera functionality while performing more consistently across Android versions (back to Lollipop) and across various devices.
