        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        startForeground(2, notification);


    }

AutoCancel does not work when service is still on foreground. Try remove service from foreground:

startForeground(2, notification);
stopForeground(false); //false - do not remove generated notification
