SoundPoolがサウンドを再生していません

Question

SoundPoolを使用して自分のアクティビティでサウンドを再生しようとしていますが、サウンドが聞こえません。

private void beginGame(){ 
     setContentView(R.layout.activity_splash1); 

     if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP){ 
      AudioAttributes aa = new AudioAttributes.Builder() 
        .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC) 
        .setUsage(AudioAttributes.USAGE_GAME) 
        .build(); 


      sp = new SoundPool.Builder() 
        .setMaxStreams(10) 
        .setAudioAttributes(aa) 
        .build(); 
     }else{ 
      sp = new SoundPool(10, AudioManager.STREAM_MUSIC,1); 
     } 

     sid = sp.load(Splash1.this,R.raw.bubble,1); 
     sp.play(sid,1,1,1,0,0.99f); 

     Thread loading = new Thread() { 
      public void run() { 
       try { 
        sleep(2000); 
        // TODO NEXT ACTIVITY 
       } 

       catch (Exception e) { 
        e.printStackTrace(); 
       } 

       finally { 
        finish(); 
       } 
      } 
     }; 

     loading.start(); 
    }

は当初、私が働いていたプロジェクトで、私は以下の1 [AnswerSound]のようなクラスを持っていたので、私はいつもそれのインスタンスを取得し、私は必要があるとして、任意のメソッドを呼び出します。私はあなたがそれを見て、それを見てくれることを願っています。

public class AnswerSound { 
private final float volume; 
private Context context; 

private SoundPool correctAnswerSoundPool; 
private int correctAnswerSoundID; 
boolean correctLoaded = false; 


private SoundPool wrongAnswerSoundPool; 
private int wrongAnswerSoundID; 
boolean wrongLoaded = false; 
public AnswerSound(Context context) 
{ 
    this.context = context; 
    correctAnswerSoundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 10); 
    correctAnswerSoundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener(){ 
    @Override 
     public void onLoadComplete(SoundPool soundPool, int sampleId, int status) { 
     correctLoaded = true; 
         } 
      } 
    ); 

    wrongAnswerSoundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 10); 

    wrongAnswerSoundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() 
    { 
    @Override 
    public void onLoadComplete(SoundPool soundPool, int sampleId, int status) { 
     wrongLoaded = true; 
     } 
     } 

    ); 
    //assign the sound IDS 
    correctAnswerSoundID = correctAnswerSoundPool.load(context, R.raw.correct_answer, 1); 

    wrongAnswerSoundID = wrongAnswerSoundPool.load(context, R.raw.wrong_answer_sound_effect, 2); 

    //getting the user sound settings 
    AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE); 

    float actualVolume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
    float maxVolume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
    volume = actualVolume/maxVolume; 

    //then you can play the sound by checking if the sound is loaded 
} 



public void playCorrectAnswerSound() 
{ 
    if (correctLoaded) { 
     correctAnswerSoundPool.play(correctAnswerSoundID, volume, volume, 1, 0, 1f); 
    } 

} 
public void playWrongAnswerSound() { 
    if (wrongLoaded) { 
     wrongAnswerSoundPool.play(wrongAnswerSoundID, volume, volume, 1, 0, 1f); 
    } 
} 

}
