Thank you for the report!

The likely fix for this is that R8 should not do outlining for library builds, which seems to have gone under the radar. We will update this issue once we have a fix that you can use.

A fix for this has landed on our 1.6 branch. You can try it out by updating your top build.gradle file with:

buildscript {

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

    dependencies {
        classpath 'com.android.tools:r8:1.6.46'          // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:X.Y.Z' // Your current AGP version.
     }
}
