| `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaBrowser` | Browses media content offered by a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaLibraryService` in addition to the `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController` functions. |

*** ** * ** ***

A controller that interacts with a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession`, a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSessionService` hosting a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession`, or a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaLibraryService` hosting a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaLibraryService.MediaLibrarySession`. The `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession` typically resides in a remote process like another app but may be in the same process as this controller. It implements `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` and the player commands are sent to the underlying `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` of the connected `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession`. It also has session-specific commands that can be handled by `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession.Callback`.

4. [Backward Compatibility with platform and legacy media sessions](https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#BackwardCompatibility)

## Controller Lifecycle

When a controller is created with the `https://developer.android.com/reference/kotlin/androidx/media3/session/SessionToken` for a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession` (i.e. session token type is `https://developer.android.com/reference/kotlin/androidx/media3/session/SessionToken#TYPE_SESSION()`), the controller will connect to the specific session.

When a controller is created with the `https://developer.android.com/reference/kotlin/androidx/media3/session/SessionToken` for a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSessionService` (i.e. session token type is `https://developer.android.com/reference/kotlin/androidx/media3/session/SessionToken#TYPE_SESSION_SERVICE()` or `https://developer.android.com/reference/kotlin/androidx/media3/session/SessionToken#TYPE_LIBRARY_SERVICE()`), the controller binds to the service for connecting to a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession` in it. `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSessionService` will provide a session to connect.

When you're done, use `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#releaseFuture(java.util.concurrent.Future<? extends androidx.media3.session.MediaController>)` or `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#release()` to clean up resources. This also helps the session service to be destroyed when there's no controller associated with it. Releasing the controller will still deliver all pending commands sent to the session and only unbind from the session service once these commands have been handled, or after a timeout of `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#RELEASE_UNBIND_TIMEOUT_MS()`.

## Threading Model

Methods of this class should be called from the application thread associated with the `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getApplicationLooper()`. Otherwise, `https://developer.android.com/reference/java/lang/IllegalStateException.html` will be thrown. Also, the methods of `https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener` and `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController.Listener` will be called from the application thread.

## Package Visibility Filter

The app targeting API level 30 or higher must include a `<queries>` element in their manifest to connect to a service component of another app like `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSessionService`, `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaLibraryService`, or `androidx.media.MediaBrowserServiceCompat`). See the following example and [this guide](https://developer.android.com/training/package-visibility) for more information.

```kotlin
<!-- As intent actions -->
<intent>
  <action android:name="androidx.media3.session.MediaSessionService" />
</intent>
<intent>
  <action android:name="androidx.media3.session.MediaLibraryService" />
</intent>
<intent>
  <action android:name="android.media.browse.MediaBrowserService" />
</intent>
<!-- Or, as a package name -->
<package android:name="package_name_of_the_other_app" />
```

## Backward Compatibility with platform and legacy media sessions

In addition to `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession`, the controller also supports connecting to a platform or legacy media session - `https://developer.android.com/reference/android/media/session/MediaSession.html` and `
android.support.v4.media.session.MediaSessionCompat`.

To request legacy sessions to play media, use one of the `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setMediaItem(androidx.media3.common.MediaItem)` methods and set either `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem#mediaId()`, `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem.RequestMetadata#mediaUri()` or `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem.RequestMetadata#searchQuery()`. Once the controller is `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#prepare()`, the controller triggers one of the following methods on `
android.support.v4.media.session.MediaSessionCompat.Callback` depending on the provided information and the value of `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getPlayWhenReady()`:

- `onPrepareFromUri`
- `onPlayFromUri`
- `onPrepareFromMediaId`
- `onPlayFromMediaId`
- `onPrepareFromSearch`
- `onPlayFromSearch`

Other playlist change methods, like `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#addMediaItem(androidx.media3.common.MediaItem)` or `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#removeMediaItem(int)`, trigger the `MediaSessionCompat.Callback.onAddQueueItem` and `
MediaSessionCompat.Callback.onRemoveQueueItem` callbacks. Check `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getAvailableCommands()` to see if playlist modifications are `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#COMMAND_CHANGE_MEDIA_ITEMS()` by the legacy session.

When connected to a platform or legacy media session, some `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` methods and features are not supported by the underlying legacy API:

- Tracks and track selection: `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getCurrentTracks()` returns `https://developer.android.com/reference/kotlin/androidx/media3/common/Tracks#EMPTY()`, `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getTrackSelectionParameters()` returns `https://developer.android.com/reference/kotlin/androidx/media3/common/TrackSelectionParameters#DEFAULT()`, and `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setTrackSelectionParameters(androidx.media3.common.TrackSelectionParameters)` is ignored.
- Video surfaces: Setting a video surface via `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setVideoSurface(android.view.Surface)`, `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setVideoSurfaceHolder(android.view.SurfaceHolder)`, `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setVideoSurfaceView(android.view.SurfaceView)`, or `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setVideoTextureView(android.view.TextureView)` logs a warning and is ignored.
- Player volume: `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getVolume()` returns `1.0f`, and `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setVolume(float)` logs a warning and is ignored. Note that device volume control via `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setDeviceVolume(int)` is supported if the session provides remote volume handling.
- Text cues: `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getCurrentCues()` returns `https://developer.android.com/reference/kotlin/androidx/media3/common/text/CueGroup#EMPTY_TIME_ZERO()`.
- Playback suppression: `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getPlaybackSuppressionReason()` returns `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#PLAYBACK_SUPPRESSION_REASON_NONE()`.
- Ad information: `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getCurrentAdGroupIndex()` and `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getCurrentAdIndexInAdGroup()` return `https://developer.android.com/reference/kotlin/androidx/media3/common/C#INDEX_UNSET()`.
- Playlist metadata: `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setPlaylistMetadata(androidx.media3.common.MediaMetadata)` is ignored.
- Ratings: `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setRating(java.lang.String,androidx.media3.common.Rating)` is only supported for the currently playing media item; calling it for any other item is ignored.

## Constants

### DEFAULT_PLATFORM_CALLBACK_AGGREGATION_TIMEOUT_MS

```
@UnstableApi
protected const val DEFAULT_PLATFORM_CALLBACK_AGGREGATION_TIMEOUT_MS = 100: Long
```

### KEY_MEDIA_NOTIFICATION_CONTROLLER_FLAG

```
@UnstableApi
const val KEY_MEDIA_NOTIFICATION_CONTROLLER_FLAG = "androidx.media3.session.MediaNotificationManager": String!
```

Key to mark the connection hints of the media notification controller.

For a controller to be `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSession#isMediaNotificationController(androidx.media3.session.MediaSession.ControllerInfo)`, this key needs to be used to `https://developer.android.com/reference/android/os/BaseBundle.html#putBoolean(java.lang.String, boolean)` in the connection hints to true. Only an internal controller that has the same package name as the session can be used as a media notification controller.

When using a session within a `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaSessionService` or `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaLibraryService`, the service connects a media notification controller automatically. Apps can do this for standalone session to configure the platform session in the same way.

### RELEASE_UNBIND_TIMEOUT_MS

```
@UnstableApi
const val RELEASE_UNBIND_TIMEOUT_MS = 30000: Long
```

The timeout for handling pending commands after calling `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#release()`. If the timeout is reached, the controller is unbound from the session service even if commands are still pending.

    args: Bundle!
): ListenableFuture<SessionResult!>!
```

Sends a custom command to the session for the given `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem`.

Calling this method is equivalent to calling `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#sendCustomCommand(androidx.media3.session.SessionCommand,android.os.Bundle)` and including the `https://developer.android.com/reference/kotlin/androidx/media3/common/MediaItem#mediaId()` in the argument bundle with key `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaConstants#EXTRA_KEY_MEDIA_ID()`.

A command is not accepted if it is not a custom command or the command is not in the list of `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#getAvailableSessionCommands()`.

Interoperability: When sending a custom command to `
android.support.v4.media.session.MediaSessionCompat`, `https://developer.android.com/reference/kotlin/androidx/media3/session/SessionResult#resultCode()` will always be `https://developer.android.com/reference/kotlin/androidx/media3/session/SessionResult#RESULT_SUCCESS()` because the session has no way to send a result back from `
android.support.v4.media.session.MediaSessionCompat.Callback#onCustomAction(String, Bundle)`.

| Parameters |
|---|---|
| `command: https://developer.android.com/reference/kotlin/androidx/media3/session/SessionCommand!` | The custom command. |

android.support.v4.media.session.MediaSessionCompat`, setting a video surface is not supported and calls to this method are ignored.

### setVideoTextureView

```
fun setVideoTextureView(textureView: TextureView?): Unit
```

Sets the onto which video will be rendered. The player will track the lifecycle of the surface automatically.

Consider using via #setVideoSurfaceView instead of \* . 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 methods must be the thread associated with #getApplicationLooper().

This method must only be called if #COMMAND_SET_VIDEO_SURFACE is \* #getAvailableCommands() available.

Interoperability: When connected to `
android.support.v4.media.session.MediaSessionCompat`, setting a video surface is not supported and calls to this method are ignored.

### setVolume

```
fun setVolume(volume: @FloatRange(from = 0, to = 1) Float): Unit
```

Sets the audio volume, valid values are between 0 (silence) and 1 (unity gain, signal unchanged), inclusive.

This method must only be called if #COMMAND_SET_VOLUME is \* #getAvailableCommands() available.

Interoperability: When connected to `
android.support.v4.media.session.MediaSessionCompat`, setting player volume is not supported and calls to this method are ignored. Remote device volume can be controlled via `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setDeviceVolume(int)`.

### 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
```

If the audio volume is 0, sets the audio volume to a non-zero value decided by the Player to be the most appropriate.

This method must only be called if #COMMAND_SET_VOLUME is \* #getAvailableCommands() available.

Interoperability: When connected to `
android.support.v4.media.session.MediaSessionCompat`, unmuting the player is not supported and calls to this method are ignored. Remote device volume can be unmuted via `https://developer.android.com/reference/kotlin/androidx/media3/session/MediaController#setDeviceMuted(boolean)`.
