Socket connection question

[EpsilonOrionis]

Hi, I would connect an Android device with a server on wich I've created a listening socket with Node.js. I tested it with Telnet and the server returns me back what I send it through the socket. But I didn't understand how can I use AndroidAsync library to create a socket (client) and connect to my server. In the example provided in the description I don't understand where a socket can be created with the combination address/port. Could someone post a snippet or a gist to let me understand, how to create a socket and connect to the server?
