Question

I've looked for examples on how to get the android device LED to blink and I've gotten the message about not being able to resolve LED_NOTIFICATION_ID to a variable. My code is below. Is there anyone that can tell me why I'm receiving this error? 

private void redFlashLight(Context context)
    {
        NotificationManager nm = ( NotificationManager ) context.getSystemService( context.NOTIFICATION_SERVICE );
        Notification notif = new Notification();
        notif.ledARGB = 0xFFff0000;
        notif.flags = Notification.FLAG_SHOW_LIGHTS;
        notif.ledOnMS = 100; 
        notif.ledOffMS = 100; 
        notif.flags = Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_ONLY_ALERT_ONCE;
        nm.notify(LED_NOTIFICATION_ID, notif);
    }
Was it helpful?

Solution

You haven't declared LED_NOTIFICATION_ID as a variable then. Look for misspellings. Is it supposed to be qualified with a class name?
