Just for context: ViewModel has a final package-private method named clear. That method is unrelated to any method defined in another package in a subclass called clear. Have we accidentally messed that up. We would not be the first ones to do so. In fact any sub class of ViewModel that has a clear method will not work on Dalvik: https://b.corp.google.com/issues/150809965 :-\

The override of package private final methods was something I looked at earlier and we should handle the case correctly - except for the case where we have -allowaccessmodification. That seem to not be the case for this example so I will take a closer look.

OK, so this was an error on our part - we had some caching that prevented us from marking the method live and we therefore pruned it (by inserting throw null). I have backported fixes to the 2.1 and 2.2. branch. For trying out the patch to 2.1 add the following to your top-level build.gradle file:

buildscript {

    repositories {
        maven {
            url 'https://storage.googleapis.com/r8-releases/raw'
        }
    }

    dependencies {
        classpath 'com.android.tools:r8:2.1.76'          // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:X.Y.Z' // Your current AGP version.
     }
}
