Question

I’m trying to create a notification when an alarm fires. No problem so far.
A notification is shown. The problem is on my device (2.1 Update 1) it is displayed as an ongoing notification. While on another device (2.2) it is working fine and is actually shown as a one time only notification. Has anyone experienced this behaviour, and more important has anyone been able to fix it. It seems like 2.1 is not respecting the FLAG_ONLY_ALERT_ONCE or any flags for that mather. See my code below. Any help would be appreciated.

public class AlarmHandler extends BroadcastReceiver {

NotificationManager nm;

@Override
public void onReceive(Context context, Intent intent) {
    Debug.log("Alarm notification received");

    nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    CharSequence from = intent.getStringExtra("AlarmType");
    CharSequence message = intent.getStringExtra("AlarmType");

    Intent newIntent = new Intent(context, Splashscreen.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, intent.getIntExtra("RequestCode", 0),
            newIntent, Intent.FLAG_ACTIVITY_NEW_TASK);

    Notification notif = new Notification(R.drawable.icon,
            null, System.currentTimeMillis());

    notif.setLatestEventInfo(context, from, message, contentIntent);
    notif.flags |= Notification.FLAG_ONLY_ALERT_ONCE | Notification.FLAG_AUTO_CANCEL;

    Debug.log("flags: "+notif.flags);
    Debug.log("Defaults: "+notif.flags);

    nm.notify(intent.getIntExtra("RequestCode", 0), notif);
}

}

Please find below values and definition for each one. Hope you can get idea from this.

1. FLAG_ONLY_ALERT_ONCE = 8
   Definition : It should be set if you want the sound and/or vibration play each time the notification is sent, even if it has not been canceled before that.

2. FLAG_ONGOING_EVENT = 2
   Definition: It should be set if this notification is in reference to something that is ongoing, like a phone call. It should not be set if this notification is in reference to something that happened at a particular point in time, like a missed phone call.

3. FLAG_AUTO_CANCEL = 16
   Definition: The notification should be canceled when it is clicked by the user

Also you if you want to cancel the notification manually then use below code

  nm.cancel(id);
