|---|---|
| `https://developer.android.com/reference/kotlin/androidx/media3/transformer/CompositionPlayer` | A `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` implementation that plays `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` of media assets. |
| `https://developer.android.com/reference/kotlin/androidx/media3/test/utils/FakePlayer` | A fake `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` that uses `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer`'s minimal number of default methods implementations to build upon to simulate realistic playback scenarios for testing. |
| `https://developer.android.com/reference/kotlin/androidx/media3/common/ForwardingSimpleBasePlayer` | A `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer` that forwards all calls to another `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` instance. |

*** ** * ** ***

A base implementation for `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` that reduces the number of methods to implement to a minimum.

Implementation notes:

- Subclasses must override `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#getState()` to populate the current player state on request.
- The `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State` should set the `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State.Builder#setAvailableCommands(androidx.media3.common.Player.Commands)` to indicate which `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` methods are supported.
- All setter-like player methods (for example, `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#setPlayWhenReady(boolean)`) forward to overridable methods (for example, `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#handleSetPlayWhenReady(boolean)`) that can be used to handle these requests. These methods return a `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListenableFuture.html` to indicate when the request has been handled and is fully reflected in the values returned from `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#getState()`. This class will automatically request a state update once the request is done. If the state changes can be handled synchronously, these methods can return Guava's `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/Futures.html#immediateVoidFuture()`.
- Subclasses can manually trigger state updates with `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#invalidateState()`, for example if something changes independent of `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` method calls.

This base class handles various aspects of the player implementation to simplify the subclass:

<!-- -->

- The `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State` can only be created with allowed combinations of state values, avoiding any invalid player states.
- Only functionality that is declared as `https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Command` needs to be implemented. Other methods are automatically ignored.
- Listener handling and informing listeners of state changes is handled automatically.
- The base class provides a framework for asynchronous handling of method calls. It changes the visible playback state immediately to the most likely outcome to ensure the user-visible state changes look like synchronous operations. The state is then updated again once the asynchronous method calls have been fully handled.

Releases the player. This method must be called when the player is no longer required. The player must not be used after calling this method.

This method must only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_RELEASE()` is `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getAvailableCommands()`.

### removeListener

```
fun removeListener(listener: Player.Listener!): Unit
```

Unregister a listener registered through `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#addListener(androidx.media3.common.Player.Listener)`. The listener will no longer receive events.

| Parameters |
|---|---|
| `listener: https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener!` | The listener to unregister. |

### removeMediaItems

```
fun removeMediaItems(fromIndex: Int, toIndex: Int): Unit
```

Removes a range of media items from the playlist.

This method must only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_CHANGE_MEDIA_ITEMS()` is `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getAvailableCommands()`.

| Parameters |
|---|---|
| `fromIndex: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The index at which to start removing media items. If the index is larger than the size of the playlist, the request is ignored. |
| `toIndex: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The index of the first item to be kept (exclusive). If the index is larger than the size of the playlist, media items up to the end of the playlist are removed. |

### replaceMediaItems

```
fun replaceMediaItems(
    fromIndex: Int,
    toIndex: Int,
    mediaItems: (Mutable)List<MediaItem!>!
): Unit
```

Replaces the media items at the given range of the playlist.

Implementations of this method may attempt to seamlessly continue playback if the currently playing media item is replaced with a compatible one (e.g. same URL, only metadata has changed).

This method must only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_CHANGE_MEDIA_ITEMS()` is `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getAvailableCommands()`.

Note that it is possible to replace a range with an arbitrary number of new items, so that the number of removed items defined by `fromIndex` and `toIndex` does not have to match the number of added items defined by `mediaItems`. As result, it may also change the index of subsequent items not touched by this operation.

| Parameters |
|---|---|
| `fromIndex: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The start of the range. If the index is larger than the size of the playlist, the request is ignored. |
| `toIndex: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The first item not to be included in the range (exclusive). If the index is larger than the size of the playlist, items up to the end of the playlist are replaced. |
| `mediaItems: (https://kotlinlang.org/api/core/kotlin-stdlib/kotlin.collections/-mutable-list/index.html)https://kotlinlang.org/api/core/kotlin-stdlib/kotlin.collections/-list/index.html<https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem!>!` | The `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem` to replace the range with. |

### setAudioAttributes

```
fun setAudioAttributes(
    audioAttributes: AudioAttributes!,
    handleAudioFocus: Boolean
): Unit
```

Sets the attributes for audio playback, used by the underlying audio track. If not set, the default audio attributes will be used. They are suitable for general media playback.

Setting the audio attributes during playback may introduce a short gap in audio output as the audio track is recreated. A new audio session id will also be generated.

If tunneling is enabled by the track selector, the specified audio attributes will be ignored, but they will take effect if audio is later played without tunneling.

If audio focus should be handled, the `https://developer.android.com/reference/kotlin/androidx/media3/common/AudioAttributes#usage()` must be `https://developer.android.com/reference/kotlin/androidx/media3/common/C#USAGE_MEDIA()` or `https://developer.android.com/reference/kotlin/androidx/media3/common/C#USAGE_GAME()`. Other usages will throw an `https://developer.android.com/reference/java/lang/IllegalArgumentException.html`.

This method must only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_SET_AUDIO_ATTRIBUTES()` is `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getAvailableCommands()`.

| Parameters |
|---|---|
| `audioAttributes: https://developer.android.com/reference/kotlin/androidx/media3/common/AudioAttributes!` | The attributes to use for audio playback. |
| `handleAudioFocus: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html` | True if the player should handle audio focus, false otherwise. |

### setVideoSurfaceView

```
fun setVideoSurfaceView(surfaceView: SurfaceView?): Unit
```

Sets the `https://developer.android.com/reference/android/view/SurfaceView.html` onto which video will be rendered. The player will track the lifecycle of the surface automatically.

The thread that calls the `https://developer.android.com/reference/android/view/SurfaceHolder.Callback.html` methods must be the thread associated with `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getApplicationLooper()`.

This method must only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_SET_VIDEO_SURFACE()` is `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getAvailableCommands()`.

Consider using `https://developer.android.com/reference/android/view/SurfaceView.html` via `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#setVideoSurfaceView(android.view.SurfaceView)` instead of `https://developer.android.com/reference/android/view/TextureView.html`. `https://developer.android.com/reference/android/view/SurfaceView.html` generally causes lower battery consumption, and has better handling for HDR and secure content. See [Choosing a surface type](https://developer.android.com/guide/topics/media/ui/playerview#surfacetype) for more information.

The thread that calls the `https://developer.android.com/reference/android/view/TextureView.SurfaceTextureListener.html` methods must be the thread associated with `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getApplicationLooper()`.

This method must only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_SET_VIDEO_SURFACE()` is `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getAvailableCommands()`.

| Parameters |
|---|---|
| `volume: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-float/index.html` | Linear output gain to apply to all audio channels. |

### stop

```
fun stop(): Unit
```

Stops playback without resetting the playlist. Use `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#pause()` rather than this method if the intention is to pause playback.

Calling this method will cause the playback state to transition to `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#STATE_IDLE()` and the player will release the loaded media and resources required for playback. The player instance can still be used by calling `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#prepare()` again, and `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#release()` must still be called on the player if it's no longer required.

Calling this method does not clear the playlist, reset the playback position or the playback error.

This method must only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_STOP()` is `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getAvailableCommands()`.

### unmute

```
fun unmute(): Unit

| `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListenableFuture.html<*>!` | A `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListenableFuture.html` indicating the completion of all immediate `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State` changes caused by this call. |

### handleStop

```
@ForOverride
protected fun handleStop(): ListenableFuture<*>!
```

Handles calls to `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#stop()`.

Will only be called if `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_STOP()` is available.

| Returns |
|---|---|
| `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListenableFuture.html<*>!` | A `https://guava.dev/releases/snapshot-android/api/docs/com/google/common/util/concurrent/ListenableFuture.html` indicating the completion of all immediate `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State` changes caused by this call. |

### invalidateState

```
protected fun invalidateState(): Unit
```

Invalidates the current state.

Triggers a call to `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#getState()` and informs listeners if the state changed.

Note that this may not have an immediate effect while there are still player methods being handled asynchronously. The state will be invalidated automatically once these pending synchronous operations are finished and there is no need to call this method again.

### seekTo

```
protected fun seekTo(
    mediaItemIndex: Int,
    positionMs: Long,
    @Player.Command seekCommand: Int,
    isRepeatingCurrentItem: Boolean
): Unit
```

Seeks to a position in the specified `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem`.

| Parameters |
|---|---|
| `mediaItemIndex: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The index of the `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem`. If the original seek operation did not directly specify an index, this is the most likely implied index based on the available player state. If the implied action is to do nothing, this will be `https://developer.android.com/reference/kotlin/androidx/media3/common/C#INDEX_UNSET()`. |
| `positionMs: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html` | The seek position in the specified `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem` in milliseconds, or `https://developer.android.com/reference/kotlin/androidx/media3/common/C#TIME_UNSET()` to seek to the media item's default position. If the original seek operation did not directly specify a position, this is the most likely implied position based on the available player state. |
| `@https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Command seekCommand: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The `https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Command` used to trigger the seek. |
| `isRepeatingCurrentItem: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html` | Whether this seeks repeats the current item. |

### verifyApplicationThread

```
protected fun verifyApplicationThread(): Unit
```

Throws an `https://developer.android.com/reference/java/lang/IllegalStateException.html` if the the thread calling this method does not match the `https://developer.android.com/reference/android/os/Looper.html` thread that was specified upon construction of this instance.

Subclasses can use this method to verify that their own defined methods are also accessed by the correct thread.
