Public functions

canDisconnect

Added in 1.1.0

fun canDisconnect(): Boolean

Gets whether this route supports disconnecting without interrupting playback.

Returns
Boolean	True if this route can disconnect without stopping playback, false otherwise.

connect

Added in 1.8.0

@MainThread
fun connect(): Unit

Connects this route without selecting it.

A route may be selected or connected. Route selection is performed using the select method. The media router library supports a single selected route which is typically the active playback device chosen by the user. This method enables connection to additional routes while maintaining the current route selection. If the specified route is already selected, this method has no effect.

The route controller dialog should display only the selected route, as this is the one users directly interact with. Connected routes are typically managed by the application in the background and are not generally relevant to the user.

After calling this method to connect a route, the application will receive the onRouteConnected callback when the connection is established. The connected RouteInfo can then be used to send control commands to the route. If the connection fails, the application receives the onRouteDisconnected callback with error details.

Must be called on the main thread.

disconnect

Added in 1.8.0

@MainThread
fun disconnect(): Unit

Disconnects this route.

If it is a connected route, then it will disconnect this route. If it is a selected route, disconnecting this route will do nothing.

After calling this method to disconnect a route, the application receives the onRouteDisconnected callback.

Must be called on the main thread.

getConnectionState

Added in 1.1.0

fun getConnectionState(): Int

Gets the connection state of the route.

Returns
Int	The connection state of this route: CONNECTION_STATE_DISCONNECTED, CONNECTION_STATE_CONNECTING, or CONNECTION_STATE_CONNECTED.

getControlFilters

Added in 1.1.0

fun getControlFilters(): (Mutable)List<IntentFilter!>

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

Returns
(Mutable)List<IntentFilter!>	A list of intent filters that specifies the media control intents that this route supports.

See also
MediaControlIntent

Returns
Uri?	The URI of the icon representing this route, or null if none.

getId

Added in 1.1.0

fun getId(): String

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
String	The unique id of the route, never null.

getMediaRouteDescriptor

Added in 1.8.0

fun getMediaRouteDescriptor(): MediaRouteDescriptor?

Returns the MediaRouteDescriptor of this media route info or null if it is not updated by its provider yet.

getPlaybackStream

Added in 1.1.0

fun getPlaybackStream(): Int

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

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

getPlaybackType

Added in 1.1.0

fun getPlaybackType(): Int

Gets the type of playback associated with this route.

Returns
Int	The type of playback associated with this route: PLAYBACK_TYPE_LOCAL or PLAYBACK_TYPE_REMOTE.

getPresentationDisplay

Added in 1.1.0

@MainThread
fun getPresentationDisplay(): Display?

Gets the Display that should be used by the application to show a android.app.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 callback and show or dismiss its android.app.Presentation accordingly when the display becomes available or is removed.

This method only makes sense for live video routes.

Must be called on the main thread.

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