here is the DatabaseHelper.java:121

database = dbHelper.getWritableDatabase();

here is the SettingsActivity line 80 code:

if (!db.isOpen())
            db.open();

Answer 1

Make sure you do execute db.close(); in order to close your database before switching to another activity

@Override
protected void onStop() {
    super.onStop();

    //closing database connection
    if(db != null)
        db.close();
}

Answer 2

You should close it too... Close it when an Exception occurs or in any case it should never be left open since its System resource
