Official Description: Contains support code for tree composition

CommonsWare’s Notes

Jetpack Compose is Google’s next-generation UI construction framework and toolkit for Android app development. The long-term objective is to replace the View-based system with one that is designed to work well with reactive APIs and is based on modern UI approaches.

Right now (October 2019), Jetpack Compose is in a pre-alpha state.

This particular artifact is the runtime engine for Compose, knowing how to build up trees of UI nodes and maintain them in the face of reactive changes to data.

See the compose-compiler artifact for more resources related to Jetpack Compose.
