Upgrade to Android 8.0 Adaptive Icon Error

Trying to update some library.
Update Cordova to 8.0
Updated Android to 8.0
still have Ionic CLI as 3.20.

Trying to get on the new firebase stuff so I don’t have any many build problems. Yet I have build problems.

Getting this error
FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:app:processDebugResources’.

Android resource linking failed
/home/dev/Ionic-app/apps/TestAPP/platforms/android/app/build/intermediates/merged_manifests/debug/AndroidManifest.xml:31: AAPT: error: resource mipmap/ic_launcher_round (aka TESTAPP:mipmap/ic_launcher_round) not found.

Not really sure where to start.
