<p>
Priority is an indication of how much of the user's
valuable attention should be consumed by this
notification. Low-priority notifications may be hidden from
the user in certain situations, while the user might be
interrupted for a higher-priority notification.
The system sets a notification's priority based on various factors including the
setPriority value. The effect may differ slightly on different platforms.

@param pri Relative priority for this notification. Must be one of
           the priority constants defined by {@link NotificationCompat}.
           Acceptable values range from {@link
           NotificationCompat#PRIORITY_MIN} (-2) to {@link
           NotificationCompat#PRIORITY_MAX} (2).
