replaceMediaItems

public void replaceMediaItems(
    int fromIndex,
    int toIndex,
    List<MediaItem> mediaItems
)

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 COMMAND_CHANGE_MEDIA_ITEMS is available.

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
`int fromIndex`	The start of the range. If the index is larger than the size of the playlist, the request is ignored.
`int toIndex`	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.
`List<MediaItem> mediaItems`	The `media items` to replace the range with.

seekTo

public void seekTo(
    int mediaItemIndex,

    boolean isRepeatingCurrentItem
)

Seeks to a position in the specified MediaItem.

Parameters
`int mediaItemIndex`	The index of the `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 `INDEX_UNSET`.
`long positionMs`	The seek position in the specified `MediaItem` in milliseconds, or `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.
`@Player.Command int seekCommand`	The `Player.Command` used to trigger the seek.
`boolean isRepeatingCurrentItem`	Whether this seeks repeats the current item.

setAudioAttributes

public void setAudioAttributes(
    AudioAttributes audioAttributes,
    boolean handleAudioFocus
)

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 the device is running a build before platform API version 21, audio attributes cannot be set directly on the underlying audio track. In this case, the usage will be mapped onto an equivalent stream type using getStreamTypeForAudioUsage.

If audio focus should be handled, the usage must be USAGE_MEDIA or USAGE_GAME. Other usages will throw an .

This method must only be called if COMMAND_SET_AUDIO_ATTRIBUTES is available.

Parameters
`AudioAttributes audioAttributes`	The attributes to use for audio playback.
`boolean handleAudioFocus`	True if the player should handle audio focus, false otherwise.

setDeviceMuted

Parameters
`boolean muted`	Whether to set the device to be muted or not
`@C.VolumeFlags int flags`	Either 0 or a bitwise combination of one or more `C.VolumeFlags`.

setDeviceVolume

public void setDeviceVolume(int volume)

setDeviceVolume

public void setDeviceVolume(int volume, @C.VolumeFlags int flags)

Note that this method affects the device volume. To change the volume of the current stream only, use setVolume.

This method must only be called if COMMAND_SET_DEVICE_VOLUME_WITH_FLAGS is available.

Parameters
`int volume`	The volume to set.
`@C.VolumeFlags int flags`	Either 0 or a bitwise combination of one or more `C.VolumeFlags`.

setMediaItems

public void setMediaItems(List<MediaItem> mediaItems, boolean resetPosition)

This method must only be called if COMMAND_CHANGE_MEDIA_ITEMS is available.

Parameters
`List<MediaItem> mediaItems`	The new `media items`.
`boolean resetPosition`	Whether the playback position should be reset to the default position in the first `Timeline.Window`. If false, playback will start from the position defined by `getCurrentMediaItemIndex` and `getCurrentPosition`.

setMediaItems

public void setMediaItems(
    List<MediaItem> mediaItems,
    int startIndex,
    long startPositionMs
)

Clears the playlist and adds the specified media items.

This method must only be called if COMMAND_CHANGE_MEDIA_ITEMS is available.

Parameters
`List<MediaItem> mediaItems`	The new `media items`.
`int startIndex`	The `MediaItem` index to start playback from. If `INDEX_UNSET` is passed, the current position is not reset.
`long startPositionMs`	The position in milliseconds to start playback from. If `TIME_UNSET` is passed, the default position of the given `MediaItem` is used. In any case, if `startIndex` is set to `INDEX_UNSET`, this parameter is ignored and the position is not reset at all.

Throws
`androidx.media3.common.IllegalSeekPositionException`	If the provided `startIndex` is not within the bounds of the list of media items.

setPlayWhenReady

public void setPlayWhenReady(boolean playWhenReady)

setPlaybackParameters

public void setPlaybackParameters(PlaybackParameters playbackParameters)

Attempts to set the playback parameters. Passing DEFAULT resets the player to the default, which means there is no speed or pitch adjustment.

Parameters
`PlaybackParameters playbackParameters`	The playback parameters.

        .buildUpon()
        .setMaxVideoSizeSd()
        .build())

This method must only be called if COMMAND_SET_TRACK_SELECTION_PARAMETERS is available.

setVideoSurface

public void setVideoSurface(@Nullable Surface surface)

Sets the Surface onto which video will be rendered. The caller is responsible for tracking the lifecycle of the surface, and must clear the surface by calling setVideoSurface(null) if the surface is destroyed.

If the surface is held by a SurfaceView, TextureView or then it's recommended to use setVideoSurfaceView, setVideoTextureView or setVideoSurfaceHolder rather than this method, since passing the holder allows the player to track the lifecycle of the surface automatically.

This method must only be called if COMMAND_SET_VIDEO_SURFACE is available.

Parameters
`@Nullable Surface surface`	The `Surface`.

setVideoSurfaceHolder

public void setVideoSurfaceHolder(@Nullable SurfaceHolder surfaceHolder)

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

Parameters
`@Nullable SurfaceHolder surfaceHolder`	The surface holder.

setVideoSurfaceView

public void setVideoSurfaceView(@Nullable SurfaceView surfaceView)

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

The thread that calls the SurfaceHolder.Callback methods must be the thread associated with getApplicationLooper.

This method must only be called if COMMAND_SET_VIDEO_SURFACE is available.

Parameters
`@Nullable SurfaceView surfaceView`	The surface view.

setVideoTextureView

public void setVideoTextureView(@Nullable TextureView textureView)

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

Consider using SurfaceView via setVideoSurfaceView instead of . SurfaceView generally causes lower battery consumption, and has better handling for HDR and secure content. See Choosing a surface type for more information.

The thread that calls the TextureView.SurfaceTextureListener methods must be the thread associated with getApplicationLooper.

This method must only be called if COMMAND_SET_VIDEO_SURFACE is available.

Parameters
`@Nullable TextureView textureView`	The texture view.

setVolume

public void setVolume(float volume)

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 available.

Parameters
`float volume`	Linear output gain to apply to all audio channels.

stop

public void stop()

Stops playback without resetting the playlist. Use pause rather than this method if the intention is to pause playback.

Calling this method will cause the playback state to transition to STATE_IDLE and the player will release the loaded media and resources required for playback. The player instance can still be used by calling prepare again, and 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 COMMAND_STOP is available.
