Development for Android

What is covered

This tutorial covers topic of using Compose Multiplatform for multiplatform build that includes Android

Intro

Compose Multiplatform build doesn't contain any Android artifacts. Instead it references Jetpack Compose Android artifacts published by Google. This way we ensure that libraries built for Android using Jetpack libraries are compatible with Compose Multiplatform.

Usage

Jetpack Compose interoperability is enabled on the publication level - nothing needs to be explicitly enabled.

The easiest way to start is to use Kotlin Project Wizard with Compose Multiplatform template - one of the target platform is Android.

To see how it could be achieved see the multiplatform template.

Versioning

Compose Multiplatform 1.0.0 references Jetpack Compose 1.1.0-beta02. If one wants to use a different version, they could explicitly override Jetpack Compose dependencies to the Android module (or to the androidMain sourceset in MPP module) like this:

dependencies {
    implementation("androidx.compose.material:material:1.1.0-beta04")
}

However please note, that Kotlin Compiler version used for Android must match.

Android Gradle Plugin (AGP) version

For multiplatform Android modules using AGP 4.1.3 with the block like

dependencies {
    classpath("com.android.tools.build:gradle:4.1.3")
}

is recommended. We're working on providing compatibility with more recent AGP versions, see KT-49835 and KT-49789. Also if one uses IntelliJ IDEA bundled Android plugin may have compatibility issues with recent AGP.
