Socket timeout not working

问题

I have a TCP Socket running on a C# machine. I need to connect that server socket from Android via Server IP and port as below:

InetAddress serverAddr = InetAddress.getByName(serverIp);
Socket socket = new Socket(serverAddr, serverPort);
socket.setSoTimeout(10*1000);

If c# machine doesn't have socket running on Android it hangs on:

Socket socket = new Socket(serverAddr, serverPort);

I need to implement 5 seconds as timeout like if it doesn't find server socket on this ip it could simply timeout.

Thoughts please..

回答1:

May this help you:

Create the socket with the no parameters constructor like this:

Socket socket = new Socket();

Then use

socket.connect(remoteAddress, timeout);

Another Way:

Socket socket= new Socket();   
socket.connect(new InetSocketAddress(hostip,port_num),connection_time_out); 

回答2:

InetAddress serverAddr = InetAddress.getByName(serverIp);
Socket socket = new Socket();
socket.connect(serverAddr, timeout);
