Method Detail

onTimelineChanged

public void onTimelineChanged(Timeline timeline,
                              @Nullable
                              java.lang.Object manifest,
                              int reason)

Description copied from interface: Player.EventListener

Called when the timeline and/or manifest has been refreshed.

Note that if the timeline has changed then a position discontinuity may also have occurred. For example, the current period index may have changed as a result of periods being added or removed from the timeline. This will not be reported via a separate call to Player.EventListener.onPositionDiscontinuity(int).

Specified by:

onTimelineChanged in interface Player.EventListener

Parameters:

timeline - The latest timeline. Never null, but may be empty.

manifest - The latest manifest. May be null.

reason - The Player.TimelineChangeReason responsible for this timeline change.

onTracksChanged

public void onTracksChanged(TrackGroupArray trackGroups,
                            TrackSelectionArray trackSelections)

Description copied from interface: Player.EventListener

Called when the available or selected tracks change.

Specified by:

onTracksChanged in interface Player.EventListener

Parameters:

trackGroups - The available tracks. Never null, but may be of length zero.

trackSelections - The track selections for each renderer. Never null and always of length Player.getRendererCount(), but may contain null elements.

onLoadingChanged

public void onLoadingChanged(boolean isLoading)

Description copied from interface: Player.EventListener

Called when the player starts or stops loading the source.

Specified by:

onLoadingChanged in interface Player.EventListener

Parameters:

isLoading - Whether the source is currently being loaded.

onPlayerStateChanged

public void onPlayerStateChanged(boolean playWhenReady,
                                 int playbackState)

Description copied from interface: Player.EventListener

Called when the value returned from either Player.getPlayWhenReady() or Player.getPlaybackState() changes.

Specified by:

onPlayerStateChanged in interface Player.EventListener

Parameters:

playWhenReady - Whether playback will proceed when ready.

playbackState - One of the STATE constants.

onRepeatModeChanged

public void onRepeatModeChanged(int repeatMode)

Description copied from interface: Player.EventListener

Called when the value of Player.getRepeatMode() changes.

Specified by:

onRepeatModeChanged in interface Player.EventListener

Parameters:

repeatMode - The Player.RepeatMode used for playback.

onShuffleModeEnabledChanged

public void onShuffleModeEnabledChanged(boolean shuffleModeEnabled)

Description copied from interface: Player.EventListener

Called when the value of Player.getShuffleModeEnabled() changes.

Specified by:

onShuffleModeEnabledChanged in interface Player.EventListener

Parameters:

shuffleModeEnabled - Whether shuffling of windows is enabled.

onPlayerError

public void onPlayerError(ExoPlaybackException error)

Description copied from interface: Player.EventListener

Called when an error occurs. The playback state will transition to Player.STATE_IDLE immediately after this method is called. The player instance can still be used, and Player.release() must still be called on the player should it no longer be required.

Specified by:

onPlayerError in interface Player.EventListener

Parameters:

error - The error.

onPositionDiscontinuity

public void onPositionDiscontinuity(int reason)

Description copied from interface: Player.EventListener

Called when a position discontinuity occurs without a change to the timeline. A position discontinuity occurs when the current window or period index changes (as a result of playback transitioning from one period in the timeline to the next), or when the playback position jumps within the period currently being played (as a result of a seek being performed, or when the source introduces a discontinuity internally).

When a position discontinuity occurs as a result of a change to the timeline this method is not called. Player.EventListener.onTimelineChanged(Timeline, Object, int) is called in this case.

Specified by:

onPositionDiscontinuity in interface Player.EventListener

Parameters:

reason - The Player.DiscontinuityReason responsible for the discontinuity.

onPlaybackParametersChanged

public void onPlaybackParametersChanged(PlaybackParameters playbackParameters)

Description copied from interface: Player.EventListener

Called when the current playback parameters change. The playback parameters may change due to a call to Player.setPlaybackParameters(PlaybackParameters), or the player itself may change them (for example, if audio playback switches to passthrough mode, where speed adjustment is no longer possible).

Specified by:

onPlaybackParametersChanged in interface Player.EventListener

Parameters:

playbackParameters - The playback parameters.

onSeekProcessed

public void onSeekProcessed()

Description copied from interface: Player.EventListener

Called when all pending seek requests have been processed by the player. This is guaranteed to happen after any necessary changes to the player state were reported to Player.EventListener.onPlayerStateChanged(boolean, int).

Specified by:

onSeekProcessed in interface Player.EventListener

onTimelineChanged

@Deprecated
public void onTimelineChanged(Timeline timeline,
                                          @Nullable
                                          java.lang.Object manifest)

Deprecated. Use onTimelineChanged(Timeline, Object, int) instead.
