当MediaPlayer完成播放第一个音频时，MediaPlayer更改数据源错误 [英] MediaPlayer change DataSource Error when MediaPlayer complets Playing First Audio

问题描述

有关MediaPlayer错误的任何帮助. 当目标是更改数据源并在第一音频"调整其播放时播放第二音频".

Any one Help for MediaPlayer Error. when aim is to Change DataSource and Play second Audio when First Audio is Compliting its Playing.

我的代码如下:- mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {

My Code is below :- mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {

        @Override
        public void onCompletion(MediaPlayer arg0) 
        {

           String fileName = Environment.getExternalStorageDirectory().getAbsolutePath() + FILENAME+arrListSize+".wav";
           mMediaPlayer.release();
           mMediaPlayer = null;
           mMediaPlayer = new MediaPlayer();
           Uri uri  = Uri.parse("file://"+fileName);                                    mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            try 
            {
              mMediaPlayer.setDataSource(getApplicationContext(), uri);
              mMediaPlayer.prepare();
            } 
            catch (Exception e) 
            {                       
                e.printStackTrace();
            }

错误:-在状态32中调用setDataSource

Error :- setDataSource called in state 32

谢谢.

推荐答案

从该错误看来，MediaPlayer的先前实例未完全释放.播放完成后，调用onCompletionListener时，播放器将处于已暂停状态.您能否在发布stop MediaPlayer之前先stop MediaPlayer?

From the error, it looks like the previous instance of the MediaPlayer is not released completely. When the playback has completed, the player is in Paused state when the onCompletionListener is invoked. Can you please stop the MediaPlayer before releasing the same?

mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = NULL;
mMediaPlayer = new MediaPlayer();
...
