If you want to launch a new activity from an activity the startActivity() works. If you want to return a result from the second activity then startActivityForResult() also works. The result is passed back in an intent which is read by overriding onActivityResult in the first activity. Once again that seems to work.
However, if I want to use the returned info to update a textview (or an editview) it does not change. I have used .invalidate() to force a redraw, but still nothing changes. I have checked the returned info by writing a log entry and by displaying a toast, both show the data has changed, but the display doesn't change. I have no ideas why. I have wasted a couple of hours on this, so I give up.
