推荐答案

只要您可以使用的MediaPlayer 和播放音频文件。请查看这个很好的例子中播放音频：

Simply you can use MediaPlayer and play the audio file. Check out this nice example for playing Audio:

 public void audioPlayer(String path, String fileName){
    //set up MediaPlayer    
    MediaPlayer mp = new MediaPlayer();

    try {
        mp.setDataSource(path+File.separator+fileName);
        mp.prepare();
        mp.start();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
