Android音频开发MediaPlayer（-38， 0）错误解决

这个问题是出现在，切换音乐播放的时候，出现-38的问题，问题的原因应该是MediaPlayer没有初始化造成的吧，这篇文章给的一个思路是，切换音乐播放的时候，销毁掉之前的MediaPlayer对象，然后重现创建一个新的MediaPlayer对象

public void playPrepareAsync() {
        try {
            if (mUrl == null) {
                return;
            }
            destoryMediaPlayer();
            mMediaPlayer = new MediaPlayer();
            mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mMediaPlayer.setOnCompletionListener(this);
            mMediaPlayer.setOnPreparedListener(this);
            mMediaPlayer.setOnSeekCompleteListener(this);
            mMediaPlayer.setOnErrorListener(this);
            mMediaPlayer.setOnBufferingUpdateListener(this);
           if (mUrl.startsWith("android.resource://")) {
                mMediaPlayer.setDataSource(this, Uri.parse(mUrl));
            } else {
                mMediaPlayer.setDataSource(mUrl);
            }
            mMediaPlayer.prepareAsync();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
            Log.e(TAG, "IllegalArgumentException无法播放" + mUrl);
        } catch (IOException e) {
            Log.e(TAG, "IOException无法播放" + mUrl);
            e.printStackTrace();
        } catch (Exception e) {
            Log.e(TAG, "Exception无法播放" + mUrl);
            setErrPlayState("" + "播放失败 " + e.toString());
        }
    }
 

public void destoryMediaPlayer() {
        try {
            if (mediaPlayer != null) {
                mediaPlayer.setOnCompletionListener(null);
                mediaPlayer.setOnPreparedListener(null);
                mediaPlayer.reset();
                mediaPlayer.release();
                mediaPlayer = null;
            }
        } catch (Exception e) {
        }
    }
