Android ServerSocket EADDRINUSE

Question

我在Android上遇到TCP服务器问题。服务器必须管理来自同一用户的多个传入连接。我收到了以下错误：

02-06 17:37:44.800: W/System.err(9859): java.net.BindException: bind failed: EADDRINUSE (Address already in use)

我添加setReuseAddress(true)但没有任何改变。我正在使用的代码如下。哪里出错了？感谢

public void onStart(Intent intent, int startid) {
    t = new Thread(){
         public void run() {
             try {
                Log.d("TCP", "Server: Creating server.");
                ServerSocket ss = new ServerSocket();
                ss.setReuseAddress(true);
                ss.bind(new InetSocketAddress(TCPPORT));
                while(true) {
                    //Server is waiting for client here, if needed
                    Log.d("TCP", "Server: Waiting on packet!");
                    Socket s = ss.accept();
                    BufferedReader input = new BufferedReader(new InputStreamReader(s.getInputStream()));
                    String msg = input.readLine();
                    ......
             }
       }
};
t.start();
}

我解决了！问题是套接字必须在setReuseAddress（）语句之后绑定。
