I've seen onActivityResult get called immediately once before as well. The activity getting started by startActivityForResult had launchMode set to singleTask in the manifest. There was a message in the logs from the ActivityManager saying: "Activity is launching as a new task, so cancelling activity result."
Changing the launch mode fixed it.
