Question

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);

Answer 1

I put this in manifest

android:launchMode="singleInstance"

This fixed the problem for me. Also this answer which I have not tried which allude to other things of interest.
