AndroidX releases 🚀

Since the previous episode, there have been some AndroidX releases worth highlighting.

Graduated to stable, we can find AppCompat 1.6.0 that primarily supports Android 13 including per-language preferences and predictive back, and Room 2.5.0 that got its runtime converted from Java to Kotlin and new features such as the Upsert annotation and room-paging support for RxJava and Guava.

The Lifecycle’s new 2.6.0-alpha04 version removes the experimental annotation from the collectAsStateWithLifecycle API and deprecates the pausing dispatcher and launchWhenX APIs.

As new libraries, we can find the androidx.credentials library that helps users sign into apps, using their stored credentials including passwords and passkeys. Also new privacy sandbox libraries such as the adservices one that enables integration with Privacy Preserving APIs, and sdkruntime that contains components for building and loading Runtime enabled SDKs on old versions of Android Platform.

Videos 🎥

If you want to make your app grow, you should watch these two videos, optimize paywall conversion, and engage with push notifications, to learn about those topics and improve your app.

Donovan recorded a video about CameraX concepts to introduce you to its functionality through 4 use cases: Preview, ImageCapture, VideoCapture, and ImageAnalysis.

Chris Shmerling recorded an in-depth walkthrough of a sample app using the FLEDGE API, a component of the Privacy Sandbox on Android.
