setupPlayer(options: PlayerOptions)

Initializes the player with the specified options. These options do not apply to all platforms, see chart below.

If the player is already initialized, the promise will resolve instantly.

registerPlaybackService(serviceProvider)

Register the playback service. The service will run as long as the player runs.

This function should only be called once, and should be registered right after registering your React application with AppRegistry.

You should use the playback service to register the event handlers that must be directly tied to the player, as the playback service might keep running when the app is in background.

Param	Type	Description
serviceProvider	function	The function that must return an async service function.

useTrackPlayerEvents(events: Event[], handler: Handler)

Hook that fires on the specified events.

You can find a list of events in the events section.
