Had a similar thing with a guy who taught Android programming and was stuck on Android 2, while Android 5 or so was out. He did not know about specifying button handlers in the XML of the view and all kinds of stuff. They did not manage to set up the IDE properly for the exam, so that logging and installing the written app on a phone did not work either. Got out of it with a bad grade, because he did not see his Android 2 shit in my solution.
