Official Description: Compiler plugin that enables Compose

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 part of the build process for Compose apps, generating code in support of a @Composable-constructed UI.
