Question

我正在开发一个应用程序，我想同时播放两个mp3文件作为背景音乐，并希望分别控制每个播放器的声音。文件大小为每个5 MB

我已经完成了主音频文件但是当我尝试用它播放第二个文件时它会抛出错误

  SoundManager mSoundManager = new SoundManager();
        mSoundManager.initSounds(getBaseContext());

        mSoundManager.addSound(1,R.raw.music);
        mSoundManager.addSound(2,R.raw.mentalafslapning);
        mSoundManager.playSound(1);
        mSoundManager.playSound(2);


    }
class SoundManager
{
    private  SoundPool mSoundPool; 
     private  HashMap<Integer, Integer> mSoundPoolMap; 
     private  AudioManager  mAudioManager;
     private  Context mContext;
     private  Vector<Integer> mAvailibleSounds = new Vector<Integer>();
     private  Vector<Integer> mKillSoundQueue = new Vector<Integer>();
     private  Handler mHandler = new Handler();

     public SoundManager(){}

     public void initSounds(Context theContext) { 
       mContext = theContext;
          mSoundPool = new SoundPool(20, AudioManager.STREAM_MUSIC, 0); 
          mSoundPoolMap = new HashMap<Integer, Integer>(); 
          mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);       
     } 

     public void addSound(int Index, int SoundID)
     {
      mAvailibleSounds.add(Index);
      mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));

     }

     public void playSound(int index) { 
      // dont have a sound for this obj, return.
      if(mAvailibleSounds.contains(index)){

          int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
          int soundId = mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);

          mKillSoundQueue.add(soundId);

          // schedule the current sound to stop after set milliseconds
          mHandler.postDelayed(new Runnable() {
           public void run() {
            if(!mKillSoundQueue.isEmpty()){
             mSoundPool.stop(mKillSoundQueue.firstElement());
            }
              }
          }, 3000);
      }
     }

是否可以同时播放这两个文件并分别控制每个文件的音量？

我读过的所有评论都表明SoundPool不适用于播放长音。当每个人都获得具有完全相同参数的错误消息时，你必须对操作系统质量有点怀疑，否则这是一个惊人的巧合。
