You seem to be getting the cursors using managedQuery.

I had problems with restoring an application, which for some reason in Icecream Sandwich did not close the cursors properly. The fix was to do this for all cursors right after using them:

if (cursor != null && !cursor.isClosed()) {
  myActivity.stopManagingCursor( cursor );
  cursor.close();
}
