update date status bar icon in android

Question

I develop an app that shows date in status bar as icon(an image for every day,1,2,3,...),now my problem is that when the date change i can't sense it. is there any way that can catch the change of date and update the status bar icon.

    mNM  =(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    int resId = getResources().getIdentifier("p_"+Day_Num, "drawable", getPackageName());
    Notification notification = new Notification(resId, "", System.currentTimeMillis());
    RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
    contentView.setImageViewResource(R.id.image, resId);
    contentView.setTextViewText(R.id.title, Day);
    contentView.setTextViewText(R.id.text, Date);
    contentView.setOnClickPendingIntent(R.id.imageView1, PendingIntent.getActivity(this, 0, new Intent(this, Option.class),0));
    notification.contentView = contentView;
    Intent notificationIntent = new Intent(this, Option.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
    notification.contentIntent = contentIntent;
    notification.defaults = Notification.FLAG_NO_CLEAR;
    mNM.notify(NOTIFICATION, notification);

when I use servic Calservice.java:

 public void onCreate() {
      //code to execute when the service is first created
       alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        Intent intent = new Intent(ALARM_REFRESH_ACTION);
        pendingIntent = PendingIntent.getBroadcast(this, 0, intent,
                PendingIntent.FLAG_CANCEL_CURRENT);
        alarmReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                alarmCounted++;
                Message msg = myHandler.obtainMessage(ALARM_CODE, intent);
                myHandler.sendMessage(msg);
            }
        };
        IntentFilter filter = new IntentFilter(ALARM_REFRESH_ACTION);
        registerReceiver(alarmReceiver, filter);
        mNM  =(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        utils.getCurrentShamsidate();
        startRepeating();
   }

       public void startRepeating() {
        // We get value for repeating alarm
        int startTime =1000;
        long intervals =1000;
        // We have to register to AlarmManager
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.add(Calendar.MILLISECOND, startTime);
        // We set a repeating alarm
        alarmManager.setRepeating(AlarmManager.RTC, calendar
                .getTimeInMillis(), intervals, pendingIntent);
    }
            private void showNotification() {

    mNM.cancelAll();
    utils.getCurrentShamsidate();
    int resId = getResources().getIdentifier("p_"+Day_Num, "drawable", getPackageName());
    Notification notification = new Notification(resId, "", System.currentTimeMillis());
    RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
    contentView.setImageViewResource(R.id.image, resId);
    contentView.setTextViewText(R.id.title, Day);
    contentView.setTextViewText(R.id.text, Date);
    contentView.setOnClickPendingIntent(R.id.imageView1, PendingIntent.getActivity(this, 0, new Intent(this, Option.class),0));
    notification.contentView = contentView;
    Intent notificationIntent = new Intent(this, Option.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
    notification.contentIntent = contentIntent;
    mNM.notify(NOTIFICATION, notification);
  }
    public void doscan() {
            String Day = Day_Num;
            utils.getCurrentShamsidate();
            if(!Day_Num.equals(Day))
                showNotification();
        }

@hamhame, Why don't you try an AlarmManager, to set alarm on Every morning at 12:00 Am. in this way you can set your opration and do things pretty easily..

This link can help you more on how to set a repeating alarm for Time interval of 24 hours.

for listening to TIme/Date change by user see this answer.

you need to register a receiver(with required action given in above link) via manifest (if want to listen always ) or register in Activity/service according to your need. and in receiver you will got to know what time has been set by getting current time and can modify you AlarmReceiver too.

by this way when user change time manually,I cant change the icon – Hamhame Jul 13 '12 at 04:20
Thank you for your answer but I have problem with static {...... where I should add this? – Hamhame Jul 14 '12 at 05:48
You better register those Intent Action in Manifest file. under Receiver tag – AAnkit Jul 14 '12 at 07:31
Please see edited question,I use service for updating notification when I use debug mode it works well and when I change the date notification changes but when I run it no change happens. – Hamhame Jul 14 '12 at 08:05
for this case, create a receiver register it with intent Action which that answers shows.. Static block is just used to execute some code once – AAnkit Jul 14 '12 at 08:13
Now,I have just one Problem that is when I change date to future it works but when I change it to past not,I think that the problem relates to alarm manager setting but I dont know how to solve it – Hamhame Jul 14 '12 at 08:49
if you set it to past, AlarmManager will trigger an alarm immediately.. you should set all your alarm event according to current time – AAnkit Jul 14 '12 at 08:51
could you please explain more?,I use this alarmManager.setRepeating(AlarmManager.RTC, calendar .getTimeInMillis(), intervals, pendingIntent); – Hamhame Jul 14 '12 at 09:02
