25  * The Notification permission behavior is similar to basic, except:
26  *
27  * It can be triggered by the system. If it's system triggered we only show it until the user makes
28  * one decision. We don't make the user show it twice.
29  *
30  * It can't be explicitly requested from apps that don't yet target android T. If they try, we
31  * remove it entirely from the request, do not return a result, and take no action on it.
