WearUnsuitableOutputPlaybackSuppressionResolverListener

Kotlin |Java

@UnstableApi
public final class WearUnsuitableOutputPlaybackSuppressionResolverListener implements Player.Listener

A Player.Listener that launches a system dialog in response to PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT to allow the user to connect a suitable audio output. Also, it auto-resumes the playback when the playback suppression reason is changed from PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT to PLAYBACK_SUPPRESSION_REASON_NONE.

This listener only reacts to PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT on Wear OS devices, while being no-op for non-Wear OS devices.

The system dialog will be the Media Output Switcher if it is available on the device, or otherwise the Bluetooth settings screen.

This implementation also pauses playback when launching the system dialog. The underlying Player implementation (e.g. ExoPlayer) is expected to resume playback automatically when a suitable audio device is connected by the user.

Constants

DEFAULT_PLAYBACK_SUPPRESSION_AUTO_RESUME_TIMEOUT_MS

public static final long DEFAULT_PLAYBACK_SUPPRESSION_AUTO_RESUME_TIMEOUT_MS

The default timeout for auto-resume of suppressed playback when the playback suppression reason as PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT is removed, in milliseconds.

Public constructors

WearUnsuitableOutputPlaybackSuppressionResolverListener

public WearUnsuitableOutputPlaybackSuppressionResolverListener(
    Context context
)

Creates a new instance.

See WearUnsuitableOutputPlaybackSuppressionResolverListener for more details. The auto-resume timeout defaults to DEFAULT_PLAYBACK_SUPPRESSION_AUTO_RESUME_TIMEOUT_MS.

Parameters
`Context context`	Any context.

WearUnsuitableOutputPlaybackSuppressionResolverListener

public WearUnsuitableOutputPlaybackSuppressionResolverListener(
    Context context,
    @IntRange(from = 0) long autoResumeTimeoutMs
)

Creates a new instance.

Parameters
`Context context`	Any context.
`@IntRange(from = 0) long autoResumeTimeoutMs`	Duration in milliseconds after the playback suppression during which playback will be resumed automatically if the playback suppression reason is changed from `PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT` to `PLAYBACK_SUPPRESSION_REASON_NONE`. Calling with `autoResumeTimeoutMs = 0` will cause playback to never resume automatically.

Public methods

onEvents

public void onEvents(Player player, Player.Events events)

Called when one or more player states changed.

State changes and events that happen within one Looper message queue iteration are reported together and only after all individual callbacks were triggered.

Listeners should prefer this method over individual callbacks in the following cases:

They intend to trigger the same logic for multiple events (e.g. when updating a UI for both onPlaybackStateChanged and onPlayWhenReadyChanged).
They need access to the Player object to trigger further events (e.g. to call seekTo after a onMediaItemTransition).
They intend to use multiple state values together or in combination with Player getter methods. For example using getCurrentMediaItemIndex with the timeline provided in onTimelineChanged is only safe from within this method.
They are interested in events that logically happened together (e.g onPlaybackStateChanged to STATE_BUFFERING because of onMediaItemTransition).

Parameters
`Player player`	The `Player` whose state changed. Use the getters to obtain the latest states.
`Player.Events events`	The `Events` that happened in this iteration, indicating which player states changed.
