Мой код показывает таблицу, созданную в logcat успешно! Кроме того, показывает cursor.getCount() до records в table, но когда я download db file из проводника устройств и открываю его в db browser, он показывает 0 table.
. данные и таблицы создаются успешно. Но кажется, что db browser не показывает table records и tables.
