这是我的代码:

    public void playSound(int n) 
    {
       try {
                Log.e("n value is", "" + n);
                boolean mStartPlaying = true;
                if (mStartPlaying == true) {
                    mPlayer = new MediaPlayer();

                    Uri uri = Uri.parse("android.resource://packagename/" + beeb.mp3);
                    mPlayer.setOnCompletionListener(soundListener);
                    mPlayer.setDataSource(getContext(), uri);
                    mPlayer.prepare();
                    mPlayer.setLooping(false);
                    mPlayer.start();

                } else {
                    //   stopPlaying();
                    //rePlay.setText("Replay");
                    mPlayer.stop();
                    mPlayer.release();
                    mPlayer = null;
                }
                mStartPlaying = !mStartPlaying;


            } catch (IOException e) {
                Log.e("ERR", "prepare() failed");
            }
        }

我已经看到由于未充分释放媒体播放器而导致的问题。它似乎可以在没有适当释放的情况下继续播放 6 次，但在 7 次时它必须开始释放线程。

在启动媒体播放器或使用创建命令之前，检查它是否为空，如果不为空，则将其清除。如果它正在播放或循环播放，请先停止它。一旦它停止，然后释放它，然后使它为空。一旦完成，您应该能够安全地使用创建命令并开始播放。

   if (mp != null){
        if (mp.isPlaying()||mp.isLooping()) {
            mp.stop();
        }
        mp.release();
        mp = null;
    }


    mp = MediaPlayer.create(this,R.raw.sound);   // note that R = res folder, raw = raw subfolder holding my audio files, and sound is the name of one of the audio files


    mp.start();
