How to detect if a notification has been dismissed?

Question

Is there any way in Android to detect when a user swipes a notification to the left and deletes it? I'm using an alarmmanager to set a repeating alert and I need my repeating alert to stop when the notification is cancelled by the user. Here's my code:

Setting the repeating alert:

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), repeatFrequency, displayIntent);

My notification code:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //Get the notification ID.
    int notifID = getIntent().getExtras().getInt("Reminder_Primary_Key");

    //Get the name of the reminder.
    String reminderName = getIntent().getExtras().getString("Reminder_Name");

    //PendingIntent stores the Activity that should be launched when the user taps the notification.
    Intent i = new Intent(this, ViewLocalRemindersDetail.class);
    i.putExtra("NotifID", notifID);
    i.putExtra("notification_tap", true);

    //Add FLAG_ACTIVITY_NEW_TASK to stop the intent from being launched when the notification is triggered.
    PendingIntent displayIntent = PendingIntent.getActivity(this, notifID, i, Intent.FLAG_ACTIVITY_NEW_TASK);

    NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    Notification notif = new Notification(R.drawable.flag_red_large, reminderName, System.currentTimeMillis());

    CharSequence from = "Here's your reminder:";

    CharSequence message = reminderName;        
    notif.setLatestEventInfo(this, from, message, displayIntent);

    //Pause for 100ms, vibrate for 250ms, pause for 100ms, and vibrate for 500ms.
    notif.defaults |= Notification.DEFAULT_SOUND;
    notif.vibrate = new long[] { 100, 250, 100, 500 };
    nm.notify(notifID, notif);

    //Destroy the activity/notification.
    finish();

}

I know I need to call alarmManager.cancel(displayIntent) in order to cancel my repeating alarm. However, I don't understand where to put this code. I need to cancel the repeating alert ONLY when the user has tapped on the notification or dismissed it. Thanks for your help!

I believe that Notification.deleteIntent is what you are looking for. The doc says:

The intent to execute when the notification is explicitly dismissed by the user, either with the "Clear All" button or by swiping it away individually. This probably shouldn't be launching an activity since several of those will be sent at the same time.
