post Notification Delayed

I'm trying to post Notifications via AlarmManager delayed. For this purpose I created an AlarmReciever which currently looks like this:

public class NotificationAlarmReciever extends BroadcastReceiver{

public static final String TAG = "NotificationAlarmReciever";

public static final String KEY_NOTIFICATION_EXTRA = "NotificationExtra";
public static final String KEY_NOTIFICATION_ID = "NotificationId";


@Override
public void onReceive(Context context, Intent intent) {
    LogCat.d(TAG, "AlarmReciever Triggered");
    LogIntent(intent);
    Bundle b = intent.getExtras();
    if (b != null){
        if (b.containsKey(KEY_NOTIFICATION_EXTRA)){
            Notification n = b.<Notification>getParcelable(KEY_NOTIFICATION_EXTRA);
                    int request = 100
                    if(b.containsKey(KEY_NOTIFICATION_ID)){
                        request = b.getInt(KEY_NOTIFI开发者_如何学运维CATION_ID)
                    }
            NotificationManager manager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
            manager.notify(request, n);
        }
    }
}

private void LogIntent(Intent intent) {
    //logs Intent....

}
}

I created a TestActivty where I try to start an Alarm like this:

public void onClick(View v) {
            Context c = getApplicationContext();
            int requestCode = 333;

            Notification notification = new Notification(R.drawable.balloon_overlay_close,"ticker", System.currentTimeMillis() + Integer.parseInt(mWhen.getText().toString()));
            Intent notificationAction = new Intent(c, TestActivity.class);
            PendingIntent notificationPendingOperation = PendingIntent.getActivity(c, requestCode, notificationAction, 0);
            notification.setLatestEventInfo(c, "HEADER", "MESSAGE", notificationPendingOperation);

            AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
            Intent alarmIntent = new Intent(c, NotificationAlarmReciever.class);
            alarmIntent.putExtra(NotificationAlarmReciever.KEY_NOTIFICATION_EXTRA, notification);
            PendingIntent alarmOperation = PendingIntent.getBroadcast(c, requestCode, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//Line 127
            alarmManager.set(requestCode, notification.when, alarmOperation);
}

as soon as alarmManager.set is called I get a NullPointerException saying:

I dont know, what I am doing wrong.

Take a look at AlarmManager.set(...) documentation.

There you can see that the first parameter 'type' cannot be 333. It can be set to either ELAPSED_REALTIME, ELAPSED_REALTIME_WAKEUP, RTC or RTC_WAKEUP, which correspond to the integer values 3, 2, 1 and 0. Those are your choices.
