I currently have a SQLiteOpenHelper subclass which contains the basic table creation/upgrade/etc. logic. CursorLoader only supports queries. You may still want to use it and leverage

If there's any more information that would be helpful, I'd be glad to add it, or to upload the complete project somewhere. Additionally, I'm targeting KitKat (sdk version 19).
