[Android]アプリ開発で効果音出力を実装する方法

class MainActivity : AppCompatActivity() {

    lateinit var soundPool: SoundPool
    var soundId: Int = 0

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        button.setOnClickListener { soundPool.play(soundId, 1.0f, 1.0f, 0, 0, 1.0f) }
    }

    override fun onResume() {
        super.onResume()

        soundPool = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
                            SoundPool.Builder().setAudioAttributes(AudioAttributes.Builder()
                            .setUsage(AudioAttributes.USAGE_MEDIA).build()).setMaxStreams(1).build()
                    } else {
                        SoundPool(1, AudioManager.STREAM_MUSIC, 0)
                    }
        soundId =  soundPool.load(this, R.raw.sound01, 1)
    }

    override fun onPause() {
        super.onPause()

        soundPool.release()
    }

}
