Dump attached for further diagnosis.

Almost all of the compilation time is spent in the conditional -if rule evaluation. The rules do not seem to be using wildcards, though, so this should be possible to optimize.

Thanks for reporting this issue! A fix for it has now landed with versions 2.1.82 and 2.2.42 which are our release branches for AGP 4.1 and 4.2 respectively.

You can manually amend your build to use one of these versions by updating build.gradle ala:

buildscript {
    repositories {
        maven {
            url 'https://storage.googleapis.com/r8-releases/raw'
        }
    }
    dependencies {
        classpath 'com.android.tools:r8:<R8_VERSION>'            // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:<AGP_VERSION>' // Your current AGP version.
     }
}

where the <R8_VERSION> and <AGP_VERSION> are suitably set.

Let us know if this resolves the issue on your end.

Tested with AGP 4.1 and working great. Thanks!

is there a plan to release AGP 4.1.2 with this fix?

Thanks for letting us now it works! This fix is pushed to the branch so if a 4.1.2 cut is made this fix will be included.
