这个问题好像只出现在小米手机上  有些是因为把网络地址放在了Uri.parse( "http://xxx.mp3" ) 所以造成这个问题

我用的小米9手机 解析的是本地地址出错了

所以统一改成了： 这个颜色的代码

 MediaPlayer mMediaPlayer = new MediaPlayer();
                try {
                    mMediaPlayer.setDataSource(App.getFilesDir+"/"+split[split.length-1]);
                }catch (IOException e){
                    e.printStackTrace();
                mMediaPlayer.prepareAsync();
                mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mediaPlayer) {
                        mediaPlayer.start();
                mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                    @Override
                    public void onCompletion(MediaPlayer mp) {
                        if (mp != null) {
                            try {
                                mp.stop();
                            } catch (Exception e) {
                                e.printStackTrace();
                                mp = null;
                                mp = new MediaPlayer();
                                mp.stop();
                            mp.reset();
                            mp.release();
                            mp = null;
                            //题目音播放完毕
                            //准备A说的话 并播放声音
//                            if (null!=bean&&bean.getAnswers()!=null&&bean.getAnswers().size()>0)
//                                playA();
                mMediaPlayer.start();
