My app requires OpenGL-ES3, and states this in the Manifest.
Yet, somehow, it frequently gets launched on ES2 devices, judging from the crash logs. I don't understand how the user managed to install it on an incompatible device, but here we are.
I want to add detection for ES2-only devices. Once detected, I need the app to warn the customer and then completely shut down.
There does not seem to be a proper manner in which an android app (its process) is ended. Android will just keep it alive, even if you call something like finish().
How can I force a REAL exit of an incompatible app?
To get the openGL ES version take a look at: Is there a way to check if Android device supports openGL ES 2.0?
To exit from the app, have you try this?:
getActivity().finish();
System.exit(0);
