Android Gradle Plugin 9.0 introduces two major changes for Kotlin projects: built-in Kotlin support eliminates the need for the separate Kotlin Android plugin, and Kotlin Multiplatform projects must migrate to the new Android KMP library plugin. Library modules need to replace the Android library plugin with the new KMP library plugin, while application modules require splitting into separate app and library modules. Temporary opt-out flags are available in AGP 9.0 but will be removed in AGP 10.0 expected in 2026. Migration guides are provided for both scenarios.
