MediaRouteProvider.RouteController

public abstract class MediaRouteProvider.RouteController

Known direct subclasses
MediaRouteProvider.DynamicGroupRouteController

Provides control over a dynamic group route.


Provides control over a particular route.

The media router obtains a route controller for a route whenever it needs to control a route. When a route is selected, the media router invokes the onSelect method of its route controller. While selected, the media router may call other methods of the route controller to request that it perform certain actions to the route. When a route is unselected, the media router invokes the onUnselect method of its route controller. When the media route no longer needs the route controller it will invoke the onRelease method to allow the route controller to free its resources.

There may be multiple route controllers simultaneously active for the same route. Each route controller will be released separately.

All operations on the route controller are asynchronous and results are communicated via callbacks.
