Мой проект работал до того, как я скопировал каталог с моего старого компьютера на новый.Android Studio - база данных SQLite (функция getWritableDatabase) не работает после копии проекта
Вот мой LogCat:

Do Вы г и любая идея проблемы? Это довольно странно, потому что (я повторяю это) я получил тот же код на моем другом компьютере, и не было никаких проблем ...
Спасибо,
Moric
Thank вы, я изменил его, но у меня все еще возникает такая же проблема, когда я запускаю MainActivity. – Moric
Редактировать Ваш код поэтому можете проверить его – Vickyexpert
Done! Я думаю, проблема возникает из openDb и getWritableDatabase, потому что мой конструктор DataBase работает хорошо. – Moric
