onActivityResult fc when using SurfaceView on Android

Question

My app fc when activity that's using SurfaceView as content view calls startActivityForResult(...) and activity that has been started calls finish()

This does not happen if I change content view to something else than SurfaceView.

This would be the requested logcat:

Fix your code such that you do not start an already-started thread, and this exception will go away.
