Google has updated , the suite of libraries and tools for Android mobile development. The update includes a series of new libraries for capabilities ranging from building camera apps to benchmarking code. Google also introduced Jetpack Compose, a project aimed at simplifying UI development.

The new Android Jetpack libraries are in alpha or beta stages. These include:

  • , a beta-stage library for building apps that can be installed in a vehicle’s infotainment system via Android Automotive OS.
  • , an alpha-stage library for benchmarking Java, Kotlin, and native code. Google has used this library to prevent introduction of latency into code. The library works with the .
  • , a beta library for entering biometrics log-in credentials.
  • , an alpha library for camera app development without having to be concerned with underlying device behavior. The API is backward-compatible to Android 5.0 (API 21) or higher. 
  • ConstraintLayout2, a beta library providing a new way of customizing layouts, using helper classes. Motion and widget animation management is provided, via a type.
  • , a beta library enabling managed enterprise apps to send feedback to mobility management providers in the form of keyed app states.
  • , an alpha library providing Kotlin coroutines that are lifecycle-aware. Developers can access coroutines scopes tied to lifecycles, coroutines that are lifecycle-aware, and support for asynchronous chains with the liveData builder.
  • an alpha for implementing security best practices including encryption and a hardware-backed keystore with user presence.
  • , an alpha-stage module that offers the benefits of ViewModel, which saves UI data when a configuration is changed, and SavedState, saving application state.
  • , the next generation of ViewPager, for screen slide transitions. ViewPager2 is in an alpha state.

Google also has rolled out a preview of Jetpack Compose, a toolkit intended to simplify UI development. It combines a reactive programming model with Kotlin. Jetpack Compose can be downloaded from .
