Media Routing

As users connect their televisions, home theater systems, and music players with wireless technologies, they want to be able to play content from Android apps on these larger, louder devices. Enabling this kind of playback can turn your one-device, one-user app into a shared experience that delights and inspires multiple users.

The Android media router APIs are designed to enable media display and playback on remote receiver devices using a common user interface. App developers that implement a MediaRouter interface can then connect to the framework and play content to devices that participate in the media router framework. Media playback device manufacturers can participate in the framework by publishing a MediaRouteProvider that allows other applications to connect to and play media on the receiver devices. Figure 1 illustrates how an app connects to a receiver device through the media router framework.

Figure 1. Overview of how media route provider classes provide communication from a media app to a receiver device.

Note: If you want your app to support Google Cast devices, you should use the Cast SDK and build your app as a Cast sender. Follow the directions in the Cast documentation instead of using the MediaRouter framework directly.

Mediarouter support library

The mediarouter APIs are defined in the v7-mediarouter support library. This library is compatible with devices running Android 2.3 (API level 9) and higher and ensures a consistent experience across all of them. For detailed information about the mediarouter APIs, see the package in the API reference.

MediaRouter API
A media app uses the MediaRouter API to discover available remote playback devices and to route audio and video to them.
MediaRouteProvider API
The MediaRouteProvider API defines the capabilities of a remote playback device and makes it visible to apps that use a MediaRouter to search for alternative media paths.

Additional code samples

The Android BasicMediaRouter and Android MediaRouter samples further demonstrate the use of the APIs covered on this page.
