How can I make Exoplayer2 run in background? (Kotlin)

I am a noob in Kotlin.
I've made a streaming music player using Exoplayer2.
For running this music player in background, I tried to bind activity to service.
But it is not working.
I dont know why this player is stopped outside the app even though i add the foreground service.
Can anybody help me? :(

In order to start the foreground service, you will need a notification shown within 5 seconds of starting it. Check the following guide in the android documentation: https://developer.android.com/guide/topics/media-apps/audio-app/building-a-mediabrowserservice#mediastyle-notifications

I tried following this question Binding PlayerView with SimpleExoPlayer from a service but the sole does not works for me

Try this:
override fun onStart() {
super.onStart()
Intent(this, LocalAudioService::class.java).also { intent ->
bindService(intent, mConnection, Context.BIND_AUTO_CREATE)
}
}
initializePlayer() should not be called here. At this moment the Service is not bound yet. When the service is bound it will called in the onServiceConnected callback.

bindService(intent,mConnection, Context.BIND_AUTO_CREATE)
intent is null here . Do Asure you are getting correct and non null intent.It should be global declared as in reference example
intent = new Intent(this, AudioPlayerService.class);
here intent is globally declared.

How to play multiple audio uri sequentially using exoplayer?

I am trying to play audio using exoplayer.
I have multiple files in a local directory and I want to play them sequentially. I am trying to add multiple to URIs to MediaSource, but I couldn't find the solution.
Here, the first file is playing correctly but none of the rest. I am using the ExoPlayer version 2.9.2
Note: In my case the files in the "Articles" folder will be updated dynamically while player is running.
Please suggest a solution. My code:

private var playerNotificationManager: PlayerNotificationManager? = null

//if (dynamicConcatenatingMediaSource == null)
dynamicConcatenatingMediaSource = ConcatenatingMediaSource()

dynamicConcatenatingMediaSource?.addMediaSource(mediaSource)
player?.prepare(dynamicConcatenatingMediaSource)

return MediaDescriptionCompat.Builder()
.setMediaId("audio_id")

.setTitle("Playlist")
.setDescription("Playlist Demo")
.setExtras(extras)
.build()
}
}

Use the concatenating media source.
private val concatenatingMediaSource = ConcatenatingMediaSource()
Then create separate mediasource for each audio file and add to concatenatingMediaSource by using
concatenatingMediaSource.addMediaSource(your_media_source_object)

How to play background music through all activities using Kotlin?

How can I play a music file in the background through all activities by using Kotlin? I have looked everywhere but I only found solutions for Java not for Kotlin.
I tried using this function but I don't know how to use it:
fun playSound() {
try {
if (m.isPlaying()) {
m.stop()
m.release()
//m = MediaPlayer()
}
val descriptor = assets.openFd("backgroundsound1.mp3")
m.setDataSource(descriptor.fileDescriptor, descriptor.startOffset, descriptor.length)
descriptor.close()
m.prepare()
m.setVolume(1f, 1f)
m.setLooping(true)
m.start()
} catch (e: Exception) {
e.printStackTrace()
}
}

Here' code in kotlin code Play background music in all activities
class BackgroundSoundService : Service() {
internal lateinit var player: MediaPlayer
override fun onBind(arg0: Intent): IBinder? {
return null
}
override fun onCreate() {
super.onCreate()
val afd = applicationContext.assets.openFd("backgroundsound1.wav") as AssetFileDescriptor
val player = MediaPlayer()
player.setDataSource(afd.fileDescriptor)
player.isLooping = true // Set looping
player.setVolume(100f, 100f)
}
override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
player.start()
return 1
}
override fun onStart(intent: Intent, startId: Int) {
// TO DO
}
fun onUnBind(arg0: Intent): IBinder? {

return null
}
fun onStop() {
}
fun onPause() {
}
override fun onDestroy() {
player.stop()
player.release()
}
override fun onLowMemory() {
}
companion object {
private val TAG: String? = null
}
}

Notification Icon from URL Exoplayer

I am trying to set the notification icon in my player which is using exoplayer. I have a playlist and am using concatenatingMediaSource. I have the url of the album art for every song but I dont know how I can set it as the notification icon. I read some answers which suggested using a AsyncTask and creating the notification onPostExecute() but I don't see how I can do in exoplayer playerNotificationManager.

Thanks in advance.

You can use Glide for it in overrided function getCurrentLargeIcon
override fun getCurrentLargeIcon(
player: Player?,
callback: PlayerNotificationManager.BitmapCallback?
): Bitmap? {
loadBitmap(currentStation?.cover, callback)
return null //or stub image
}
private fun loadBitmap(url: String, callback: PlayerNotificationManager.BitmapCallback?) {
Glide.with(this)
.asBitmap()
.load(url)
.into(object : CustomTarget<Bitmap>() {
override fun onResourceReady(
resource: Bitmap,
transition: Transition<in Bitmap>?
) {
callback?.onBitmap(resource)
}
})
}

You need to override it like this
#Nullable
#Override
public Bitmap getCurrentLargeIcon(Player player, PlayerNotificationManager.BitmapCallback callback) {
Glide.with(this)
.asBitmap()
.load(uri)
.into(new CustomTarget<Bitmap>() {
#Override
public void onResourceReady(#NonNull Bitmap resource, #Nullable Transition<? super Bitmap> transition) {
callback.onBitmap(resource);
}
#Override
public void onLoadCleared(#Nullable Drawable placeholder) {
}
});
return null;
}
