kotlin-tooling-agp9-migration

To migrate a Kotlin Multiplatform library to AGP 9.0, replace the com.android.library plugin with com.android.kotlin.multiplatform.library and update your Gradle, Kotlin, and plugin declarations to align with the single-variant library model.

AGP 9.0 KMP migration requires Gradle 9.1+, AGP 9.0+, and JDK 17+ as minimum environment prerequisites. You must also update your version catalog or explicitly declare plugin dependencies to support the built-in Kotlin integration.

Replacing com.android.library with com.android.kotlin.multiplatform.library enables the new KMP library model in AGP 9.0, ensuring built-in Kotlin integration, single-variant library behavior, and proper support for Android and iOS targets.

When upgrading KMP to AGP 9.0, you must remove conflicting Kotlin Android and kapt plugins. The migration process provides specific steps to address KSP, kapt, resource, and NDK considerations under the new single-variant library model.

Yes, AGP 9.0 migration applies specifically to Kotlin Multiplatform modules using kotlin.multiplatform with Android and iOS targets, ensuring the single-variant library model and built-in Kotlin integration are properly configured.

AGP 9.0 KMP migration requires removing conflicting kapt plugins and addressing NDK, resource, and KSP considerations. Modules must use the single-variant library model, and the environment must meet the Gradle 9.1+, AGP 9.0+, and JDK 17+ minimums.
