Bringing an Activity to Front , using notification in Android

Question

I raised a notification . What i want is , that when the user clicks on the notification , my activity is brought to the front without creating a new instance of it . For this , I added the flag , REORDER_TO_FRONT , but still oncreate is being called instead of onNewIntent when i click on the notification .

This is my code -

        int icon = R.drawable.android;
        long when = System.currentTimeMillis();
        CharSequence text = "new message";
        CharSequence contentTitle = stanza.getFrom();  // message title
        CharSequence contentText = stanza.getBody();      // message text

        Intent notificationIntent = new Intent(context, ChatBox.class);
        notificationIntent.putExtra("buddyid",stanza.getFrom());
        notificationIntent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,notificationIntent, 0);


// the next two lines initialize the Notification, using the configurations above
        Notification notification = new Notification(icon, text, when);
        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        mNotificationManager.notify(1,notification);

Ok. Now try this one. Intent intent= new Intent(context, ChatBox.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); and in manifest add to your activity android:launchMode="singleTop" I think this will help you. – AnujMathur_07 Sep 21 '12 at 12:16

The solution for me for this was to make a broadcast receiver that listens to broadcast actions that the notification triggers. So basically:

Notification triggers a broadcast action with an extra the name of the activity to launch.
Broadcast receiver catches this when the notification is clicked, then creates an intent to launch that activity using the FLAG_ACTIVITY_REORDER_TO_FRONT flag
Activity is brought to the top of activity stack, no duplicates.
