Пожалуйста, помогите мне с ошибкой, ниже которой я получаю только на устройствах Huawei. Я предполагаю, что эти устройства хранят базу данных где-то еще ... или ...?
Сообщение об ошибке: android .database.sqlite.SQLiteException: нет такой таблицы: мест (Sqlite code 1 SQLITE_ERROR):, while компиляция: SELECT pl_web_id FROM мест ORDER BY pl_web_id DES C LIMIT 1, (ошибка ОС - 2: нет такого файла или каталога)
