Android 套接字代码

Question

为什么不能使用此代码打开套接字：

                try {
                    Connect=(Button)findViewById(R.id.connect);
                    InetSocketAddress address = new InetSocketAddress("192.168.1.2",54628);
                    DatagramPacket request = new DatagramPacket(cmd.getBytes(), cmd.length(), address);
                    DatagramSocket socket = new DatagramSocket();
                    socket.send(request);
                } catch (SocketException e) {
                    System.out.print("SSSS");
                }

但当我这样做时它确实有效：

    clientSocket= new Socket("192.168.1.2",54635); 
    Text.append( "\n created a socket");

您确实应该考虑回顾其他问题并接受答案（如果它们对您有用）。接受率为 0% 时，您获得帮助的可能性较小。

将 System.out.print() 语句更改为 e.printStackTrace();然后运行应用程序并复制 Logcat 的输出并将其粘贴到您的问题中。这将帮助我们了解到底出了什么问题。
