Java 媒体播放器错误（-38,0）

我正在尝试同时播放多个音频文件。然而，我确实得到了这个错误（在标题中提到）。我想知道它的原因是什么，我如何修复它。 注意：类似的问题也被提及，但没有帮助我解决

try {
        mp.setDataSource(text);
        mp.prepare();
        mp.setVolume(0.4f, 0.4f);




        songPlayer.setDataSource(song);
        songPlayer.prepare();
        songPlayer.setLooping(true);


        voicePlayer.setDataSource(voice);
        voicePlayer.prepare();
        voicePlayer.setLooping(true);
        voicePlayer.wait(5000);
        voicePlayer.setVolume(0.5f,0.5f);

    }
    catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (SecurityException e) {
        e.printStackTrace();
    } catch (IllegalStateException e) {
        e.printStackTrace();

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

    final Handler hlr = new Handler();

   final Runnable looper = new Runnable() {
       @Override
       public void run()
       {
           if(mp!=null)
           {

                mp.stop();

           }

           mp.start();

       }
   };





    mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        public void onCompletion(MediaPlayer mp)
        {
            hlr.postDelayed(looper, 5000);
        }
    });

    mp.start();

    songPlayer.start();
    voicePlayer.start();

以下是日志：
