Добрый день, у меня огромный сюрприз. Мое приложение работает, когда запускается на эмуляторе, но падает, когда я пытаюсь использовать его на реальном устройстве. Я не понимаю, как это могло случиться. Я пытаюсь вставить данные в базу данных.Android-приложение, работающее на эмуляторе не устройство
По какой-то причине ошибки возникают только при использовании устройства. Ниже приведен журнал ошибок и код.

Простите, если это небольшая ошибка, и я прошу. Я проработал несколько часов и все еще озадачен тем, как adroid может работать на эмуляторе, а не на реальном устройстве.
вы добавили разрешение Интернет к вашему XML-файл манифеста? –
Ну, в журнале говорится, что есть проблема с подключением к Интернету, а затем есть 'NullPointerException' в' com.example.divide.asteriasolutions.BookingActivity $ CreateNewProduct.doInBackground (BookingActivity.java:153) '... Итак ... есть вы там посмотрели? – avalancha
yes, Когда я использую эмулятор, он отлично работает. Я добавлю файл манифеста – user2878444
