Change Notification Intent In Android

I have a service that shows a notification that I wish that will be able to go to a specific activity of my app each time the user presses on it. Usually it would be the last one t

Solution 1:

No it wouldn't be possible to change the Activity once you have sent the notification.

You can start an Activity on your task stack that is not a problem, check out the notification service in the tutorial here:

You have to set a pending intent on the notification:

// The PendingIntent to launch our activity if the user selects this notification
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, SecondActivity.class), 0);

        // Set the info for the view that shows in the notification panel.
        notification.setLatestEventInfo(this, title, text, contentIntent);

You can see the pending intent takes a normal intent "new Intent(this, SecondActivity.class" so if you want specific behaviour (like bringing to the top instead of starting a new activity. Add the flags like you would normally to this intent. i.e. FLAG_ACTIVITY_REORDER_TO_FRONT (something like that)

Solution 2:

Since platform version 11, you can build a notification using Notification.Builder. The v4 support library has an equivalent class NotificationCompat.Builder.

You can't change the Activity once you've sent the notification, but you can update the notification with a new Intent. When you create the PendingIntent, use the flag FLAG_CANCEL_CURRENT. When you send the new notification, use the ID of the existing notification when you call NotificationManager.notify().

Also, you should be careful how you start your app. The Status Bar Notifications guide tells you how to set up the back stack.
