Мое приложение отлично работает на Android-эмуляторе. Когда я пытаюсь запустить его на своем устройстве, столбец LogCat дает мне информацию о том, что таких столбцов нет: USERNAME. В эмуляторе моя база данных SQLite создается нормально, и я могу добавлять новых пользователей и подписывать, но на устройстве есть исключение, когда я пытаюсь это сделать.Приложение для Android работает на эмуляторе, но не работает на моем устройстве Android
Вот файл журнал, когда я пытаюсь создать новый пользователь:

Кому-нибудь может помочь?
Где используется строка DATABASE_CREATE? Не могли бы вы его удалить? – user1504495
Я использую DATABASE_CREATE String в другом классе с именем DataBaseHelper. Как я сказал, на эмуляторе все работает хорошо. –
Показать, что вспомогательный класс. –
