Investigate Android Gradle Plugin 9.0 #615
Description
https://developer.android.com/build/releases/agp-9-0-0-release-notes
The
androidDSL classes now only implement the new public interfacesOver the last several years, we have introduced new interfaces for our DSL and API in order to better control which APIs are public. AGP versions 7.x and 8.x still used the old DSL types (for example
BaseExtension) which also implemented the new public interfaces, in order to maintain compatibility as work progressed on the interfaces.AGP 9.0 uses our new DSL interfaces exclusively, and the implementations have changed to new types that are fully hidden. This also removes access to the old, deprecated variant API.

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(orkotlin-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.

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.
This release completely broke another gradle plugin I'm acquainted with, https://github.com/ndtp/android-testify … fixing it was non-trivial.
Maybe it'll be an easy drop-in replacement for Skip! But I don't feel lucky…
(Fortunately, I don't think there's any urgency on this.)
