Project in Android Studio

Composite build of Compose-jb sources

Download submodules after downloading the main project:

git submodule update --init --recursive

Set this property to always update submodules on git checkout/pull/reset:

git config --global submodule.recurse true

General requirements

  • Java 11 (should be specified in JAVA_HOME)
  • [macOs/Linux] Android SDK downloaded via ./scripts/downloadAndroidSdk
  • [Windows] Android SDK downloaded from Android Studio and specified in ANDROID_SDK_ROOT. Required components:
    • Android 12
    • Build-Tools 30.0.3
    • NDK 21.3.6528147 (in folder $androidSdk/ndk, not in $androidSdk/ndk/$version)
    • CMake 3.10.2.4988404 (in folder $androidSdk/cmake, not in $androidSdk/cmake/$version)

Developing in IDE

  1. Download Android Studio from the offcial site (it is mandatory to use the version, written here). As an alternative you can use IDEA, which is compatible with this AGP version, or you can disable Android plugin in IDEA plugins, to develop non-Android targets.
  2. Set environment variables:
export ALLOW_PUBLIC_REPOS=1
export JAVA_TOOLS_JAR=$PWD/external/tools.jar
export ANDROIDX_PROJECTS=COMPOSE
export JAVA_HOME=<JDK_home> // it should point to Java 11 and contain /include/jvmti.h
  1. Set gradle properties in ~/.gradle/gradle.properties:
androidx.compose.multiplatformEnabled=true
# note that https://android.googlesource.com/platform/frameworks/support build doesn't work with jetbrains.compose.jsCompilerTestsEnabled)
jetbrains.compose.jsCompilerTestsEnabled=true
androidx.validateProjectStructure=false
  1. Open compose folder in Android Studio (not compose/frameworks/support)
  2. Download a custom Gradle 7.2 and specify it in Settings -> Build, Execution, Deployment -> Build Tools -> Gradle (because Android Studio will pick the wrong Gradle in the subproject instead of the Gradle in the root project)
  3. Specify Gradle JDK 11 in ... -> Build Tools -> Gradle
  4. [macOs/Linux] Specify Android SDK pointed to a folder, downloaded via ./scripts/downloadAndroidSdk

Scripts

Publish artifacts to the local directory out/androidx/build/support_repo/org/jetbrains/compose:

export COMPOSE_CUSTOM_VERSION=0.0.0-custom
./scripts/publish

(on Windows it doesn't build at the moment, the issue is in the line packageInspector(project, project(":compose:ui:ui-inspection") in compose/frameworks/support/compose/ui/ui/build.gradle)

Publish extended icons:

./scripts/publishExtendedIcons

Run tests for Desktop:

./scripts/testDesktop

Run tests for Web:

./scripts/testWeb

Multiplatform build

./scripts/downloadAndroidSdk
export COMPOSE_CUSTOM_VERSION=1.1.0-beta04
./scripts/publishToMavenLocal -Pcompose.platforms=all
./scripts/publishGradlePluginToMavenLocal
./scripts/publishWebComponentsToMavenLocal

-Pcompose.platforms=all could be replace with comma-separated list of platforms, such as js,jvm,androidDebug,androidRelease,macosx64,uikitx64.
