NavUtils.navigateUpTo() does not start any Activity

Question

I have two activities

I think that method is bugged. I've read support library source code, and that method check for intent's action. It only works when your App was previously created..as you've described, if you kill it from Apps preview, shouldUp method stops working.

I've fixed this using my own "shouldUpRecreateTask". When I receive a Notification that creates directly an Activity (Like your behaviour), I send from my BroadCastReceiver a custom Action inside the intent. Then, in my Method I do the next thing:

private final boolean shouldUpRecreateTask(Activity from){
    String action = from.getIntent().getAction();
    return action != null && action.equals(com.xxxxxx.activities.Intent.FROM_NOTIFICATION);
}

..........................

 if (shouldUpRecreateTask(this)) {
      TaskStackBuilder.create(this)
       .addNextIntentWithParentStack(upIntent)
       .startActivities();
 } else {
       fillUpIntentWithExtras(upIntent);
       NavUtils.navigateUpTo(this, upIntent);
 }
