Question

I know there are many topic that have the same title, but I’ve tried all of them. I couldn’t solve my problem.
The error I get is exactly this:

android.database.sqlite.SQLiteException: Can’t upgrade read-only database from version 0 to 1: /data/data/com.halilkaya.flashcard/databases/flashcarddb.db

Actually, it works on the emulator, but when I install it on my phone, it doesn’t work!

Answer 1

Hope you are dropping the table and upgrading it aagain as below

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS " + LOCATION_TABLE);
    db.execSQL("DROP TABLE IF EXISTS " + PHONE_TABLE);
    // Create tables again
    onCreate(db);

}
