Почему мое приложение рушится с IllegalArgumentException?

Question

У меня есть служба, которая начинается после установки приложения, когда служба запускает его сбой приложения. Возможно, файл базы данных еще не создан? Я не знаю, что делать.

Где может быть проблема?

Answer 1

В вашей таблице пользователей, Вы указали «COLUMN_USER_ID»

COLUMN_USER_ID+ " integer not null, 

И при вставке данных в таблице пользователей, COLUMN_USER_ID какой-то пустой. Так создавая проблему. Перед вставкой данных убедитесь, что значение столбца не равно нулю.
