MediaRouter2.RoutingController

Kotlin |Java

public class MediaRouter2.RoutingController
extends Object

java.lang.Object
↳	android.media.MediaRouter2.RoutingController

A class to control media routing session in media route provider. For example, selecting/deselecting/transferring routes to a session can be done through this class. Instances are created by MediaRouter2.transferTo(android.media.MediaRoute2Info).

Public methods

deselectRoute

Added in Android R

public void deselectRoute (MediaRoute2Info route)

Deselects a route from the remote session. After a route is deselected, the media is expected to be stopped on the deselected routes.

The given route must satisfy all of the following conditions:

ID should be included in getSelectedRoutes()
ID should be included in getDeselectableRoutes()

If the route doesn't meet any of above conditions, it will be ignored.

Parameters
`route`	`MediaRoute2Info`: This value cannot be `null`.

See also:

getControlHints

Added in Android R

public Bundle getControlHints ()

Returns
`Bundle`	the control hints used to control routing session if available. This value may be `null`.

getDeselectableRoutes

Added in Android R

public List<MediaRoute2Info> getDeselectableRoutes ()

Returns
`List<MediaRoute2Info>`	the unmodifiable list of deselectable routes for the session. This value cannot be `null`.

getId

Added in Android R

public String getId ()

Returns
`String`	the ID of the controller. It is globally unique. This value cannot be `null`.

getSelectableRoutes

Added in Android R

public List<MediaRoute2Info> getSelectableRoutes ()

Returns
`List<MediaRoute2Info>`	the unmodifiable list of selectable routes for the session. This value cannot be `null`.

getSelectedRoutes

Added in Android R

public List<MediaRoute2Info> getSelectedRoutes ()

Returns
`List<MediaRoute2Info>`	the unmodifiable list of currently selected routes This value cannot be `null`.

getVolume

Added in Android R

public int getVolume ()

Gets the current volume of the session.

When it's available, it represents the volume of routing session, which is a group of selected routes. To get the volume of a route, use MediaRoute2Info#getVolume().

Returns
`int`

See also:

MediaRoute2Info.getVolume()

getVolumeHandling

Added in Android R

public int getVolumeHandling ()

Gets information about how volume is handled on the session.

Returns
`int`	`MediaRoute2Info#PLAYBACK_VOLUME_FIXED` or `MediaRoute2Info#PLAYBACK_VOLUME_VARIABLE` Value is `MediaRoute2Info.PLAYBACK_VOLUME_FIXED`, or `MediaRoute2Info.PLAYBACK_VOLUME_VARIABLE`

getVolumeMax

Added in Android R

public int getVolumeMax ()

Gets the maximum volume of the session.

Returns
`int`

isReleased

Added in Android R

public boolean isReleased ()

Returns true if this controller is released, false otherwise. If it is released, then all other getters from this instance may return invalid values. Also, any operations to this instance will be ignored once released.

Returns
`boolean`

See also:

release()

release

Added in Android R

public void release ()

Release this controller and corresponding session. Any operations on this controller after calling this method will be ignored. The devices that are playing media will stop playing it.

selectRoute

Added in Android R

public void selectRoute (MediaRoute2Info route)

Selects a route for the remote session. After a route is selected, the media is expected to be played to the all the selected routes. This is different from MediaRouter2#transferTo(MediaRoute2Info) transferring to a route}, where the media is expected to 'move' from one route to another.

The given route must satisfy all of the following conditions:

ID should not be included in getSelectedRoutes()
ID should be included in getSelectableRoutes()

If the route doesn't meet any of above conditions, it will be ignored.

Parameters
`route`	`MediaRoute2Info`: This value cannot be `null`.

See also:

setVolume

Added in Android R

public void setVolume (int volume)

Requests a volume change for the remote session asynchronously.

Parameters
`volume`	`int`: The new volume value between 0 and `RoutingController#getVolumeMax` (inclusive).

See also:

getVolume()

toString

Added in Android R

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.
