RemoteSessionPlayer

Kotlin |Java

abstract class RemoteSessionPlayer : SessionPlayer

kotlin.Any
↳	androidx.media2.common.SessionPlayer
	↳	androidx.media2.session.RemoteSessionPlayer

Base interface for all remote media players that want media session and playback happens on the remote device through MediaRouter.

If you use this to the MediaSession, session would dispatch incoming volume change event to the player instead of changing device stream volume.

Summary

Nested classes
open	`Callback` A callback class to receive notifications for events on the remote session player.

Constants
static Int	`VOLUME_CONTROL_ABSOLUTE` The volume control uses an absolute value.
static Int	`VOLUME_CONTROL_FIXED` The volume is fixed and can not be modified.
static Int	`VOLUME_CONTROL_RELATIVE` The volume control uses relative adjustment via `adjustVolume(int)`.

Inherited constants

From class SessionPlayer

`Int`	`BUFFERING_STATE_BUFFERING_AND_PLAYABLE` Buffering state indicating the player is buffering but enough has been buffered for this player to be able to play the content. See `getBufferedPosition()` for how far is buffered already.
`Int`	`BUFFERING_STATE_BUFFERING_AND_STARVED` Buffering state indicating the player is buffering, but the player is currently starved for data, and cannot play.
`Int`	`BUFFERING_STATE_COMPLETE` Buffering state indicating the player is done buffering, and the remainder of the content is available for playback.
`Int`	`BUFFERING_STATE_UNKNOWN` Buffering state is unknown.
`Int`	`INVALID_ITEM_INDEX` Media item index is invalid. This value will be returned when the corresponding media item does not exist.
`Int`	`PLAYER_STATE_ERROR` State when the player is in error state and cannot be recovered self.
`Int`	`PLAYER_STATE_IDLE` State when the player is idle, and needs configuration to start playback.
`Int`	`PLAYER_STATE_PAUSED` State when the player's playback is paused
`Int`	`PLAYER_STATE_PLAYING` State when the player's playback is ongoing
`Int`	`REPEAT_MODE_ALL` Playing media list will be repeated.
`Int`	`REPEAT_MODE_GROUP` Playback of the playing media group will be repeated. A group is a logical block of media items which is specified in the section 5.7 of the Bluetooth AVRCP 1.6. An example of a group is the playlist.
`Int`	`REPEAT_MODE_NONE` Playback will be stopped at the end of the playing media list.
`Int`	`REPEAT_MODE_ONE` Playback of the current playing media item will be repeated.
`Int`	`SHUFFLE_MODE_ALL` Media list will be played in shuffled order.
`Int`	`SHUFFLE_MODE_GROUP` Media group will be played in shuffled order. A group is a logical block of media items which is specified in the section 5.7 of the Bluetooth AVRCP 1.6. An example of a group is the playlist.
`Int`	`SHUFFLE_MODE_NONE` Media list will be played in order.
`Long`	`UNKNOWN_TIME` Value indicating the time is unknown

Public constructors
`<init>()` Base interface for all remote media players that want media session and playback happens on the remote device through MediaRouter.

Public methods
abstract Future<SessionPlayer.PlayerResult!>	`adjustVolume(direction: Int)` Adjusts player volume with the direction.
abstract Int	`getMaxVolume()` Gets the maximum volume that can be used in `setVolume(int)`.
abstract Int	`getVolume()` Gets the current volume of this player to this player.
abstract Int	`getVolumeControlType()` Gets the volume type.
abstract Future<SessionPlayer.PlayerResult!>	`setVolume(volume: Int)` Sets the volume of the audio of the media to play, expressed as a linear multiplier on the audio samples.

Inherited functions

From class SessionPlayer

ListenableFuture<SessionPlayer.PlayerResult!>

addPlaylistItem(index: Int, @NonNull item: MediaItem)

Adds the media item to the playlist at the index. Index equals to or greater than the current playlist size (e.g. Integer#MAX_VALUE) will add the item at the end of the playlist.

If index is less than or equal to the current index of the playlist, the current index of the playlist should be increased correspondingly.

The implementation must notify registered callbacks with PlayerCallback#onPlaylistChanged(SessionPlayer, List, MediaMetadata) when it's completed.

The implementation must close the ParcelFileDescriptor
