+/**

+ * This sample demonstrates the use of the MediaRouter API to show content on a
+ * secondary display using a {@link Presentation}.
+ * </p>
+ * <p>
+ * The activity uses the {@link MediaRouter} API to automatically detect when a
+ * presentation display is available and to allow the user to control the media
+ * routes using a menu item provided by the {@link MediaRouteActionProvider}.
+ * When a presentation display is available a {@link Presentation} (implemented
+ * as a {@link SamplePresentation}) is shown on the preferred display. A button
+ * toggles the background color of the secondary screen to show the interaction
+ * between the primary and secondary screens.
+ * </p>
+ * <p>
+ * This sample requires an HDMI or Wifi display. Alternatively, the
+ * "Simulate secondary displays" feature in Development Settings can be enabled
+ * to simulate secondary displays.
