Jetpack Compose is a suite of libraries within the AndroidX ecosystem. For more information, see our project page
Jetpack Compose uses composable functions instead of XML layouts to define UI components. You can see this in action in the demos, like
androidx.compose.material.demos.ButtonDemo.kt. More information can be found in the compiler README.
Composable functions are built using a custom Kotlin compiler plugin. More information about the compiler plugin is available in this README.
To try out Jetpack Compose you need to set up the toolchain for AndroidX development. Follow the process here to check out the code.
To start the required version of Android Studio, you need to run the
ANDROIDX_PROJECTS=COMPOSE ./gradlew studio
cd path/to/checkout/frameworks/support/ ANDROIDX_PROJECTS=COMPOSE ./gradlew studio
Also if you would like to build from the command line, all gradle commands need to be run from the
frameworks/support folder. E.g. to build the demo app, run:
cd path/to/checkout/frameworks/support/ ./gradlew :compose:integration-tests:demos:installDebug
Library code for Jetpack Compose lives under the
frameworks/support/compose directory. Additionally, sample code can be found within each module in the
integration-tests subdirectories. Run the
demos app to see examples of components and behavior.
