Android Notification restarts app but want to resume

Hi I have a been able to get a notification displayed for my activity, and when the user clicks the notification the app restarts. However I just want it to reappear not restart. eg. it is a web app and I want it to come to the front when the user selects the notification..but not refresh the web page. Can I trap this intent or am I sending the wrong intent? Normally if I press the home button and click on the app icon the app comes to the fore and doesn't refresh/restart. So this is the behaviour I want. Any ideas ? ``` String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); //2.Instantiate the Notification int icon = R.drawable.notification_icon; CharSequence tickerText = "My App"; // temp msg on status line long when = System.currentTimeMillis(); Notification notification = new Notification(icon, tickerText, when); notification.flags |= Notification.FLAG_ONGOING_EVENT; //3.Define the Notification's expanded message and Intent: Context context = getApplicationContext(); CharSequence contentTitle = "Notification"; CharSequence contentText = "My app!"; // message to user Intent notificationIntent = new Intent(this, HelloAndroid2.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); //4.Pass the Notification to the NotificationManager: final int NOTIFICATION_ICON_ID = 1; mNotificationManager.notify(NOTIFICATION_ICON_ID, notification); ```
