The App Crashed due to the ViewControlLayer class

[JiatongBao]

The app was successfully installed and run on the phone. However, after it connected to the ros master, the app then crashed due to the following problem. I did not modify any part of the source code.

Same problem. When I change sdk version to 25, it still doesn't work.

I encounter the same problem in android 8.0.

You can run with the old version without crashing, but you need to modify some code to run
