这样对吗？

当我获得媒体播放器的音乐代码时,我可以通过设置以下方法来使用它的类型：

mp.setAudioStreamType(2);

但我想知道它是否足以流式传输这样的代码并保存文件,如下面的方法：

private void setDataSource(String path) throws IOException {
        if (!URLUtil.isNetworkUrl(path)) {
            mp.setDataSource(path);
        } else {
            Log.i("enter the setdata","enter the setdata");
            URL url = new URL(path);
            URLConnection cn = url.openConnection();
            cn.connect();
            InputStream stream = cn.getInputStream();
            if (stream == null)
                throw new RuntimeException("stream is null");
            File temp = File.createTempFile("mediaplayertmp","dat");
            String tempPath = temp.getAbsolutePath();
            FileOutputStream out = new FileOutputStream(temp);
            byte buf[] = new byte[128];
            do {
                int numread = stream.read(buf);
                if (numread <= 0)
                    break;
                out.write(buf,numread);
            } while (true);
            mp.setDataSource(tempPath);

            try {
                stream.close();
                Log.i("exit the setdata","exit the setdata");
            }
            catch (IOException ex) {
                Log.e(TAG,"error: " + ex.getMessage(),ex);
            }
        }
    }

直播电视节目需要额外的东西吗？请指导我.
