Android 播放音频文件的问题

Question

我已经从服务器下载了音频文件并使用它保存了

/data/data/packagename/sounds/filename.mp3

然后，如果我使用播放该音频

.MediaPlayer mp= new MediaPlayer();
            try {
                mp.setDataSource(PATH+"/"+fileName);
            } catch (IllegalArgumentException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IllegalStateException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            mp.start();

但是显示错误

MediaPlayer:start called in state 2
MediaPlayer:Error(-38,0)
MediaPlayer:Error(-38,0)

有什么问题我搜索了很多关于这个但没有解决方案请提出任何解决方案

试试这段代码，

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

    try {
        mp.setDataSource(path+"/"+filename.mp3);
    } catch (IllegalArgumentException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    try {
        mp.prepare();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    mp.start();
}
