seems to work fine Have you checked to make sure that listView is in fact not null? Debug your code, step all the way up to listView.setAdapter(simpleCursor); and hover over listView to see if it is null.
EDIT: You did find that it was in fact null, here is the most common reason(s) that I have found:
code :
listView = (ListView) findViewById(R.id.tasklist);

Any of those help Have you seen this, tried the swap cursor method, or tried just simply calling setAdapter() again?
I had a similar issue where I could not get my list to update, and what I did was just create a refreshListView() method. Now you can call this initially from your onCreate(), AND anytime a user adds something to the DB. All it does is re-bind the listview to a cursor. With all the deprecating methods (requery()), and issues with notifyDataSetChanged(), I decided this was the easiest way.

this will help I Figured out the problem. I was doing the dumb mistake of closing down the connection when the method ends where cursor gets invalid after that.
