``` @UnstableApi class WearUnsuitableOutputPlaybackSuppressionResolverListener : Player.Listener ```
*** ** * ** *** A[Player.Listener](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener)that launches a system dialog in response to[PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#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](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT())to[PLAYBACK_SUPPRESSION_REASON_NONE](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#PLAYBACK_SUPPRESSION_REASON_NONE()). This listener only reacts to[PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#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](https://developer.android.com/media/routing#output-switcher)if it is available on the device, or otherwise the Bluetooth settings screen. This implementation also pauses playback before opening the system dialog. If the user connects a suitable media output within the specified timeout, playback resumes automatically. During this timeout, a power wakelock of the[PARTIAL_WAKE_LOCK](https://developer.android.com/reference/android/os/PowerManager.html#PARTIAL_WAKE_LOCK())level is obtained to prevent the system from freezing the app. ## Summary | ### Constants |

const val DEFAULT_PLAYBACK_SUPPRESSION_AUTO_RESUME_TIMEOUT_MS: Long ``` The default timeout for auto-resume of suppressed playback when the playback suppression reason as[PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT())is removed, in milliseconds. ## Public constructors ### WearUnsuitableOutputPlaybackSuppressionResolverListener ``` WearUnsuitableOutputPlaybackSuppressionResolverListener(     context: Context! ) ``` Creates a new instance. See[WearUnsuitableOutputPlaybackSuppressionResolverListener](https://developer.android.com/reference/kotlin/androidx/media3/ui/WearUnsuitableOutputPlaybackSuppressionResolverListener#WearUnsuitableOutputPlaybackSuppressionResolverListener(android.content.Context,long))for more details. The auto-resume timeout defaults to[DEFAULT_PLAYBACK_SUPPRESSION_AUTO_RESUME_TIMEOUT_MS](https://developer.android.com/reference/kotlin/androidx/media3/ui/WearUnsuitableOutputPlaybackSuppressionResolverListener#DEFAULT_PLAYBACK_SUPPRESSION_AUTO_RESUME_TIMEOUT_MS()). | Parameters | |-----------------------------------------------------------------------------------------------|--------------| | `context: `[Context](https://developer.android.com/reference/android/content/Context.html)`!` | Any context. | ### WearUnsuitableOutputPlaybackSuppressionResolverListener ``` WearUnsuitableOutputPlaybackSuppressionResolverListener(     context: Context!,     autoResumeTimeoutMs: @IntRange(from = 0) Long ) ``` Creates a new instance. | Parameters | |-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `context: `[Context](https://developer.android.com/reference/android/content/Context.html)`!` | Any context. | | `autoResumeTimeoutMs: @`[IntRange](https://developer.android.com/reference/kotlin/androidx/annotation/IntRange)`(from = 0) `[Long](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html) | 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](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT())to[PLAYBACK_SUPPRESSION_REASON_NONE](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#PLAYBACK_SUPPRESSION_REASON_NONE()). Calling with`autoResumeTimeoutMs = 0`will cause playback to never resume automatically. | ## Public functions ### onEvents ``` fun onEvents(player: Player!, events: Player.Events!): Unit ``` Called when one or more player states changed. State changes and events that happen within one[Looper](https://developer.android.com/reference/android/os/Looper.html)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](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener#onPlaybackStateChanged(int))and[onPlayWhenReadyChanged](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener#onPlayWhenReadyChanged(boolean,int))). - They need access to the[Player](https://developer.android.com/reference/kotlin/androidx/media3/common/Player)object to trigger further events (e.g. to call[seekTo](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#seekTo(long))after a[onMediaItemTransition](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener#onMediaItemTransition(androidx.media3.common.MediaItem,int))). - They intend to use multiple state values together or in combination with[Player](https://developer.android.com/reference/kotlin/androidx/media3/common/Player)getter methods. For example using[getCurrentMediaItemIndex](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#getCurrentMediaItemIndex())with the` timeline`provided in[onTimelineChanged](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener#onTimelineChanged(androidx.media3.common.Timeline,int))is only safe from within this method. - They are interested in events that logically happened together (e.g[onPlaybackStateChanged](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener#onPlaybackStateChanged(int))to[STATE_BUFFERING](https://developer.android.com/reference/kotlin/androidx/media3/common/Player#STATE_BUFFERING())because of[onMediaItemTransition](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Listener#onMediaItemTransition(androidx.media3.common.MediaItem,int))). | Parameters | |-------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `player: `[Player](https://developer.android.com/reference/kotlin/androidx/media3/common/Player)`!` | The[Player](https://developer.android.com/reference/kotlin/androidx/media3/common/Player)whose state changed. Use the getters to obtain the latest states. | | `events: `[Player.Events](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Events)`!` | The[Events](https://developer.android.com/reference/kotlin/androidx/media3/common/Player.Events)that happened in this iteration, indicating which player states changed. |
