Android Gradle plugin Built-in Kotlin

Built-in Kotlin
Android Gradle plugin 9.0 introduces built-in Kotlin support and enables it by default. That means you no longer have to apply the org.jetbrains.kotlin.android (or kotlin-android) plugin in your build files to compile Kotlin source files. This simplifies the Kotlin integration with AGP, avoids the use of deprecated APIs, and improves performance in some cases.
Therefore, when you upgrade your project to AGP 9.0, you need to also migrate to built-in Kotlin or opt out.
You can also selectively disable built-in Kotlin support for Gradle subprojects that don't have Kotlin sources.
Runtime dependency on Kotlin Gradle plugin
To provide built-in Kotlin support, Android Gradle plugin 9.0 now has a runtime dependency on Kotlin Gradle plugin (KGP) 2.2.10. That means you no longer have to declare a KGP version, and if you use a KGP version lower than 2.2.10, Gradle will automatically upgrade your KGP version to 2.2.10. Likewise, if you use a KSP version lower than 2.2.10-2.0.2, AGP will upgrade it to 2.2.10-2.0.2 to match the KGP version.
Upgrade to a higher KGP version
To use a higher version of KGP or KSP, add the following to your top-level build file:
buildscript {
dependencies {
// For KGP
classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:KGP_VERSION")
// For KSP
classpath("com.google.devtools.ksp:symbol-processing-gradle-plugin:KSP_VERSION")
}
}Downgrade to a lower KGP version
You can only downgrade the KGP version if you've opted out of built-in Kotlin. This is because AGP 9.0 enables built-in Kotlin by default, and built-in Kotlin requires KGP 2.2.10 or higher.
