I’m running into the same issue when attempting to build with Adaptive Icons, and the aforementioned workaround in @AshleyScirra 's post (“it looks like a workaround for this is to define the legacy icons below the adaptive icons”) doesn’t work for me either. I’m on a Mac ( 10.15.6 ) with Cordova 9.0.0.

This issue should be fixed in the latest cordova-android release, (currently cordova-android@9.0.0) by https://github.com/apache/cordova-android/pull/1001

If you still have an issue please open a new issue in the cordova-android repo at https://github.com/apache/cordova-android/issues

@breautek - oh boy. What can I do to resolve this while still on cordova-android@8.1 ? I can’t migrate to @9.0.0 yet as it breaks my app in a few places, and don’t have time to step through it all for a while.

You can try forking cordova-android, branch off the rel/8.1.0 tag and apply the https://github.com/apache/cordova-android/pull/1001 patch. Then you can install the platform over git.
