I have a typical master-detail scenario. That is, first activity invokes a list fragment in which I retrieve a list using a contentprovider. An Item click on this list returns the row using a callback to activity. Activity determines device type and either fires a detail fragment (for tablets etc) or fires a detail activity (for phones). I am trying to update the list in the list activity following an update, or a delete. The adapter is located in the list fragment - as is normal. I have coded callbacks from the detail activity to the first activity. That did not work. I've done the same thing but calling back to the list fragment. That does not work. I created a hard-coded reference to the ListFragment adapter in the DetailFragment in order to call ' notifyDataSetChanged' which not surprisingly also did not work. Can someone tell me what I'm missing here?
