I ran into this problem too, and in my case it wasn't so easy to go
find all of the c.close() calls since I hadn't written any. For the
next person who runs into this, it turns out that
SimpleCursorAdapter.changeCursor() will close the previous cursor (as
documented). So instead of calling changeCursor directly, you have to
first retrieve the previous cursor and stopManaging it. It would be
nice if the second step were explicitly in the documentation too.
I considered avoiding having the cursors managed at all, since the
Adapter takes responsibility for closing the cursors, but I suspect
the automatic .deactivate() and .requery() calls are useful for saving
resources when the Activity isn't in the foreground.
