I’ve export a project for AndroidStudio with gradle from Unity 2018.3.6f1, as I’m working with my own dynamic library for android and I want to debug it.But I got the error with UnityPlayerActivity in AndroidStudio.
Then I created an empty project and export a project for AndroidStudio, and got the same error when debuging it, the stacktrace is below:
