Tests are failing in CI and reporting that they're OK #38330
Description
Probably two separate problems here, whatever caused the failure and the fact that run_tests.py is returning 0 instead of 1 on tests failure.
Caused by: java.lang.ClassNotFoundException: io.flutter.embedding.android.FlutterActivity
