Episode 129: Display, Input and Haptics

Michael, Chet and Romain in the cozy London recording studio.

In this episode, Chet and Romain travel all the way to London to have a chat with Michael Wright. This is not Michael's first time on the podcast and one again the discussion is about displays, input devices and haptics.

If you want to learn more about high refresh rate displays (90/120 Hz), HDR, audio-coupled haptics, how gamepads are supported and, curiously, about the Android API council, you found the right episode!

Episode 128: Play with App Bundles

We forgot to take a picture of ourselves
when we recorded this.
Please use your imagination.

In this episode, Chet and Florina Muntenescu (from the Android Developer Relations team) talk with Dom Elliott from the Google Play team about Android App Bundles and other Google Play features.

App bundles are the new packaging format for Android apps. They allow you to upload a single version of your app, then Google Play can distribute optimized versions of that app to users, depending on device-specific capabilities, like the selected locale(s) on the device.

We also talked about other recent Google Play features (related to bundles and not), such as on-demand delivery and in-app updates.

Episode 126: Gesture Nav

Allen, Chris, Adam, part of Tor, Dan (taking the photo),
and Chet. All of them are also in the monitor, but backwards.
Oh, and note the gym sock being used to dampen noise
on the mic. High tech stuff, ADB.

In this episode, Chet and Tor talk with Chris Banes, Adam Cohen, Dan Sandler, and Allen Huang about Gesture Navigation.

Gesture Nav is an important UI behavior change in the Android 10 release that developers should handle and test. Chris has written Gesture Nav articles recently. This conversation goes further into the background and reasons for the change, as well as techniques for dealing with it.

Note: The audio in this episode, is not up to the usual quality bar. We had the choice between recording the conversation with a non-ideal setup or not doing it at all. We chose content over quality.

Episode 125: ADB Live at the Android Dev Summit

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.

Episode 124: UX

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.

Favorite acronym: "WTFY"

Episode 122: Talk Talk

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.

Episode 121: Benchmarking

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.

Episode 106: WorkManager & Navigation

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? We try to de-mystify this naming convention and talk about how we see development and release of architecture components in general.
