Constants

public static final int PLAYBACK_TYPE_LOCAL

The default playback type, "local", indicating the presentation of the media is happening on the same device (e.g. a phone, a tablet) as where it is controlled from.

See Also
Constant Value: 0 (0x00000000)

public static final int PLAYBACK_TYPE_REMOTE

A playback type indicating the presentation of the media is happening on a different device (i.e. the remote device) than where it is controlled from.

See Also
Constant Value: 1 (0x00000001)

public static final int PLAYBACK_VOLUME_FIXED

Playback information indicating the playback volume is fixed, i.e. it cannot be controlled from this object. An example of fixed playback volume is a remote player, playing over HDMI where the user prefers to control the volume on the HDMI sink, rather than attenuate at the source.

See Also
Constant Value: 0 (0x00000000)

public static final int PLAYBACK_VOLUME_VARIABLE

Playback information indicating the playback volume is variable and can be controlled from this object.

See Also
Constant Value: 1 (0x00000001)

Public Methods

public List<IntentFilter> getControlFilters ()

Gets a list of media control intent filters that describe the capabilities of this route and the media control actions that it supports.

Returns
  • A list of intent filters that specifies the media control intents that this route supports.
See Also

public String getDescription ()

Gets the user-visible description of the route.

The route description describes the kind of destination represented by the route. It may be a user-supplied string, a model number or brand of device.

Returns
  • The description of the route, or null if none.

public Bundle getExtras ()

Gets a collection of extra properties about this route that were supplied by its media route provider, or null if none.

public String getId ()

Gets the unique id of the route.

The route unique id functions as a stable identifier by which the route is known. For example, an application can use this id as a token to remember the selected route across restarts or to communicate its identity to a service.

Returns
  • The unique id of the route, never null.

public String getName ()

Gets the user-visible name of the route.

The route name identifies the destination represented by the route. It may be a user-supplied name, an alias, or device serial number.

Returns
  • The user-visible name of a media route. This is the string presented to users who may select this as the active route.

public int getPlaybackStream ()

Gets the audio stream over which the playback associated with this route is performed.

Returns
  • The stream over which the playback associated with this route is performed.

public int getPlaybackType ()

Gets the type of playback associated with this route.

Returns

public Display getPresentationDisplay ()

Gets the Display that should be used by the application to show a Presentation on an external display when this route is selected. Depending on the route, this may only be valid if the route is currently selected.

The preferred presentation display may change independently of the route being selected or unselected. For example, the presentation display of the default system route may change when an external HDMI display is connected or disconnected even though the route itself has not changed.

This method may return null if there is no external display associated with the route or if the display is not ready to show UI yet.

The application should listen for changes to the presentation display using the onRoutePresentationDisplayChanged(MediaRouter, MediaRouter.RouteInfo) callback and show or dismiss its Presentation accordingly when the display becomes available or is removed.

This method only makes sense for live video routes.

Returns
  • The preferred presentation display to use when this route is selected or null if none.
