+<p>
+    If you wish, you can set the priority of a notification. The priority acts
+    as a hint to the device UI about how the notification should be displayed.
+    To set a notification's priority, call {@link
+    android.support.v4.app.NotificationCompat.Builder#setPriority(int)
+    NotificationCompat.Builder.setPriority()} and pass in one of the {@link
+    android.support.v4.app.NotificationCompat} priority constants. There are
+    five priority levels, ranging from {@link
+    android.support.v4.app.NotificationCompat#PRIORITY_MIN} (-2) to {@link
+    android.support.v4.app.NotificationCompat#PRIORITY_MAX} (2); if not set, the
+    priority defaults to {@link
+    android.support.v4.app.NotificationCompat#PRIORITY_DEFAULT} (0).
+</p>
+<p> For information about setting an appropriate priority level, see "Correctly
+    set and manage notification priority" in the <a
+    href="{@docRoot}design/patterns/notifications.html">Notifications</a> Design
