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!

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.

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.
