SoundPool in Service not loading

Question

I have a SoundPool that I want to stay loaded in different fragments. So I load it with an intent for a service in my starting activities onCreate, and then try to play it with other intents in onClickListeners (and other methods) in the other fragments. Even though it prints the lines to confirm the sounds being loaded, afterwards it does not play them, saying "sample X not READY". What am I doing wrong?

Here´s the Main Activities onCreate:

override fun onCreate(savedInstanceState: Bundle?) {
    var pIntent = Intent(this, SoulSoundService::class.java)
    pIntent.putExtra("Load", "Ein")
    startService(pIntent)
    super.onCreate(savedInstanceState)
    setContentView(com.example.soulfetchnew.R.layout.activity_fullscreen)
    mVisible = false
    }

and the onclicklistener (in a fragment)

override fun onResume() {
    super.onResume()
    majpentlevelbutton.setOnClickListener {playPing()
    it.findNavController().navigate(R.id.action_levelSelectFragment_to_levelFragment)
    }
}

fun playPing(){
    val pIntent = Intent(activity, SoulSoundService::class.java)
    pIntent.putExtra("name", R.raw.dbping)
    activity?.startService(pIntent)
}

And the service:

open class SoulSoundService : Service() {

private lateinit var mSoundPool: SoundPool
private val myBinder = MyLocalBinder()

override fun onCreate() {
    val mAttributes = AudioAttributes.Builder()
        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
        .setUsage(AudioAttributes.USAGE_GAME)
        .build()

    mSoundPool = SoundPool.Builder()
        .setMaxStreams(14)
        .setAudioAttributes(mAttributes)
        .build()
}

override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
    if (intent.hasExtra("Load")) {
        loadPings()
    }
    if (intent.hasExtra("name")) {
        soundID = intent.getIntExtra("Name", soundID)
        playPing(soundID)
    }
    if (intent.hasExtra("Stop")) {
        stopSelf()
    }
    return super.onStartCommand(intent, flags, startId)
}


fun playPing(soundID: Int){
    mSoundPool.play(soundID, 1f, 1f, 1, 1, 1f)
}

fun loadPings() {
    val abping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.abping, 1)
    val aping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.aping, 1)
    val bbping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.bbping, 1)
    val bping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.bping, 1)
    val cping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.cping, 1)
    val dbping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.dbping, 1)
    val dping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.dping, 1)
    val ebping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.ebping, 1)
    val eping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.eping, 1)
    val fping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.fping, 1)
    val gbping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.gbping, 1)
    val gping = mSoundPool.load(this, com.example.soulfetchnew.R.raw.gping, 1)

    mSoundPool.setOnLoadCompleteListener(object: SoundPool.OnLoadCompleteListener {
        override fun onLoadComplete(mSoundPool: SoundPool, sampleId:Int,
                           status:Int) {
            println("SOUNDS ARE LOADED")            
        }
    })

}

Answer 1

You have to use the value returned by load() to play the sound. That is, abping, aping, etc. You are trying to play them based on the resource ID, which is incorrect. The resource ID is only used for loading the sound (as you have done).
