Context context = getApplicationContext();
CharSequence contentTitle = "My notification Title";
CharSequence contentText = "This is the message";
Intent notificationIntent = new Intent(NotificationTest.this, NotificationTest.class);
 
//options
notification.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "4"); //using sound
notification.vibrate = new long[]{0,100,200,300}; //vibrate (don't forget to add permission)
                                       
// led light
notification.ledARGB = 0xff00ff00;
