On API level 16 and above a big content view is also defined that is used for the * 'expanded' notification. The notification is created by the NotificationCompat.Builder. * The expanded content view is set directly on the {@link android.app.Notification} once it has been build. * (See {@link android.app.Notification#bigContentView}.)
The content views are inflated as {@link android.widget.RemoteViews} directly from their XML layout * definitions using {@link android.widget.RemoteViews#RemoteViews(String, int)}.
