Jetbrains has a new Code-coverage tool in development, named Kover, which is a gradle-plugin.

It is in an early version for now, and this article mentions it does not support instrumentation tests yet, but that might be outdated since it seems to have preliminary support for Jetpack Compose:

And the official docs mention support for Android and build-variants, but indeed, no support for instrumentation tests for now, according to the Features-paragraph:

Support for Kotlin Android projects with build variants (instrumentation tests executing on the Android device are not supported yet).

If you test this, please let me know if it works for you.
