我整天都在努力通过本地服务器读取音频文件（mp3），使用DatagramSocket＆amp; DatagramPacket类。这是代码＆amp;错误日志：
客户端
OutputStream out = client.getOutputStream();
...
// after receiving the datapacket => I'm trying to write it to a Http socket
// which is not working
udpSocket.receive(dataPacket);
http_outputStream.write(dataPacket.getData(),dataPacket.getOffset(),
dataPacket.getLength());
我对处理音频/视频文件的功能有一些疑问，因为在尝试时 从服务器发送一些文本到客户端，一切都很好。 我正在使用：
服务器端
File audio = new File(Environment.getExternalStorageDirectory()+File.separator, "bob.mp3");
FileInputStream is = new FileInputStream(audio);
is.read(buf);
DatagramSocket socket = new DatagramSocket();
DatagramPacket out = new DatagramPacket(buf, buf.length, hostAddress, UDP_PORT);
socket.send(out);

感谢您的帮助。
编辑： 我忘了提到类似“服务器”的代码每次将“mp3-data”发送到客户端的同一端口时都使用不同的端口。这没关系吗？
