Description

When using media3 exoplayer to implement an audio player, a large number of ANRs are encountered. The basic implementation is as follows.

class AudioService : MediaSessionService() {

	override fun onCreate() {
		super.onCreate()
		exoPlayer = ExoPlayer.Builder(this, RenderersFactory(this)).build()
		exoPlayer?.setAudioAttributes(uAmpAudioAttributes, true)
		exoPlayer?.setHandleAudioBecomingNoisy(true)
		exoPlayer?.addListener(playerListener)

		val sessionBuilder = MediaSession.Builder(this, exoPlayer!!)
		sessionBuilder.setCallback(ExtendMediaSessionCallback())
		sessionBuilder.setId(packageName)
		packageManager?.getLaunchIntentForPackage(packageName)?.let { sessionIntent ->
        sessionBuilder.setSessionActivity(
	          PendingIntent.getActivity(
	            this@AudioService,
	            0,
	            sessionIntent,
	            if (Build.VERSION.SDK_INT >= 23) FLAG_IMMUTABLE else FLAG_UPDATE_CURRENT
	          )
	        )
	      }
      	mediaSession = sessionBuilder.build()
	}
}

import kotlin.coroutines.CoroutineContext
import kotlinx.coroutines.*
import kotlinx.coroutines.guava.await

class AudioConnection(context: Context, serviceComponent: ComponentName) { // serviceComponent is AudioService

	private val coroutineContext: CoroutineContext = Dispatchers.Main
	private val scope = CoroutineScope(coroutineContext + SupervisorJob())

	val player: Player? get() = controller
	var controller: MediaController? = null

	init {
		scope.launch {
	      val newController = MediaController.Builder(context, SessionToken(context, serviceComponent))
	        .setListener(ControllerListener())
	        .buildAsync()
	        .await()
	      newController.addListener(playerListener)
	      controller = newController
	    }
	}
}

AudioConnection is a singleton. Initialize AudioConnection and use it to play audio after initialization is complete.
AudioConnection.getInstance(context, ComponentName(context, AudioService::class.java))

Two examples of stack trace are as follows. There are some other stack traces with slightly different contents.
