The sub-activity has the same characteristics when started by the map- view activity, where it reports a result back, as when started by the GLSurfaceView activity, where it does not report back. It is the same sub-activity, started by the same code, with the same arguments to the intent.
BTW, how do you set something "singleTask" or "singleInstance"? I don't have a setting like either. Thanks for your response!
