NavUtils.shouldUpRecreateTask fails on JellyBean

Question

I have an application that issues notifications that when selected start an activity. According to the Android docs I can use NavUtils.shouldUpRecreateTask to check whether the

This is not correct! When you start from the notification you have to create the stack when building the notification as explained here: http://developer.android.com/guide/topics/ui/notifiers/notifications.html#NotificationResponse

Therefore when creating the notification you'll have to do this:

Intent resultIntent = new Intent(this, ResultActivity.class);
// ResultActivity is the activity you'll land on, of course
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent to the top of the stack
// make sure that in the manifest ResultActivity has parent specified!!!
stackBuilder.addNextIntent(resultIntent);
// Gets a PendingIntent containing the entire back stack
PendingIntent resultPendingIntent =
        stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

and then when you click on the UP button you need the regular code, which is:

if (NavUtils.shouldUpRecreateTask(this, intent)) {
    // This activity is NOT part of this app's task, so
    // create a new task when navigating up, with a
    // synthesized back stack.
    TaskStackBuilder.create(this)
    // Add all of this activity's parents to the back stack
            .addNextIntentWithParentStack(intent)
            // Navigate up to the closest parent
            .startActivities();
} else {
    NavUtils.navigateUpTo(this, intent);
}

This works perfectly for me.
