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.

Episode 139: AndroidX. Jetpack. AndroidX. Jetpack. Whatever.
Romain, Chet, Alan, Nick, and a little tiny Tor in the upper-right corner In this episode, Romain, Chet and Tor talked with Nick Anthony and Alan Viverette from the AndroidX team about... AndroidX. And Jetpack. And androidx. (Spoiler alert: androidx is the set of libraries. Jetpack is that... plus opinionated guidance. AndroidX is the name of the team that ships this stuff). We also talked about the release cadence (currently every two weeks, up from every-several-months a couple of years ago), the standards for release naming/versioning, API standards, and everything else in the world of AndroidX infrastructure and release.

Episode 138: Animated IME — Oh, my!
Chet, Romain, Jorim, Adrian and Taran. Oh and Tor hiding the upper right. In this episode, Tor, Chet and Romain are joined by Jorim, Adrian and Taran from the Window Manager team. We discussed newly announced capabilities of the IME (Input Method Editor) in Android 11. These new APIs allow applications to react in real-time to IME animations and thus provide a more polished and seamless user experience. It also happens to be the answer to one of your most requested features: knowing when the on-screen keyboard is showing. Subscribe to the podcast feed or download the audio file directly.

Episode 137: Accessibility
Chet, Qasid, Romain, Sally, Tor, and a very mysterious guest in a very dark room in the lower-right. In this episode, Romain, Chet and Tor talked (remotely!) with Sally Yuen and Qasid Sadiq from the Accessibility team. We discussed the kinds of tools and facilities that their team provides, and how developers can (and should!) make their applications more accessible. We talked about Accessibility Services, Talkback, Accessibility Scanner, organizational complexities of accessibility efforts, and more. Pro tip: Avoid creating custom widgets by using the built-in widgets in the platform to inherit accessibility functionality for free.

Episode 136: Remoting
Tor, Chet, and Romain, remembering the way things used to be, back when there was a recording studio instead of closets at home. In this episode, Romain, Chet and Tor chat with zero guests about the current work-from-home reality, and about adjustments we've all made as we change the way we work.

Episode 135: Audio Podcast
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.
