class ForwardingSimpleBasePlayer : SimpleBasePlayer

kotlin.Any
↳	androidx.media3.common.BasePlayer
	↳	androidx.media3.common.SimpleBasePlayer
		↳	androidx.media3.common.ForwardingSimpleBasePlayer

A SimpleBasePlayer that forwards all calls to another Player instance.

The class can be used to selectively override getState or handle{Action} methods:

new ForwardingSimpleBasePlayer(player) {
  &#64;Override
  protected State getState() {
    State state = super.getState();
    // Modify current state as required:
    return state.buildUpon().setAvailableCommands(filteredCommands).build();
  }

  &#64;Override
  protected ListenableFuture<?> handleSetRepeatMode(int repeatMode) {
    // Modify actions by directly calling the underlying player as needed:
    getPlayer().setShuffleModeEnabled(true);
    // ..or forward to the default handling with modified parameters:
    return super.handleSetRepeatMode(Player.REPEAT_MODE_ALL);
  }
}

This base class handles many aspect of the player implementation to simplify the subclass, for example listener handling. See the documentation of SimpleBasePlayer for a more detailed description.

ForwardingSimpleBasePlayer

ForwardingSimpleBasePlayer(player: Player!)

Creates the forwarding player.

Parameters
`player: Player!`	The `Player` to forward to.

Protected functions

getState

protected fun getState(): SimpleBasePlayer.State!

Returns the current State of the player.

The State should include all available commands indicating which player methods are allowed to be called.

Note that this method won't be called while asynchronous handling of player methods is in progress. This means that the implementation doesn't need to handle state changes caused by these asynchronous operations until they are done and can return the currently known state directly. The placeholder state used while these asynchronous operations are in progress can be customized by overriding getPlaceholderState if required.

handleAddMediaItems

Parameters
`index: Int`	The index at which to add the items. The index is in the range 0 <= `index`<= `getMediaItemCount`.
`mediaItems: (Mutable)List<MediaItem!>!`	The media items to add.

Returns
`ListenableFuture<*>!`	A `ListenableFuture` indicating the completion of all immediate `State` changes caused by this call.
