MediaRouteProvider

public abstract class MediaRouteProvider
extends Object

java.lang.Object
   ↳ android.support.v7.media.MediaRouteProvider

Media route providers are used to publish additional media routes for use within an application. Media route providers may also be declared as a service to publish additional media routes to all applications in the system.

The purpose of a media route provider is to discover media routes that satisfy the criteria specified by the current MediaRouteDiscoveryRequest and publish a MediaRouteProviderDescriptor with information about each route by calling setDescriptor(MediaRouteProviderDescriptor) to notify the currently registered MediaRouteProvider.Callback.

The provider should watch for changes to the discovery request by implementing onDiscoveryRequestChanged(MediaRouteDiscoveryRequest) and updating the set of routes that it is attempting to discover. It should also handle route control requests such as volume changes or media control intents by implementing onCreateRouteController(String) to return a MediaRouteProvider.RouteController for a particular route.

A media route provider may be used privately within the scope of a single application process by calling MediaRouter.addProvider to add it to the local MediaRouter. A media route provider may also be made available globally to all applications by registering a MediaRouteProviderService in the provider's manifest. When the media route provider is registered as a service, all applications that use the media router API will be able to discover and used the provider's routes without having to install anything else.

This object must only be accessed on the main thread.
