He is getting the loopback (internal) IP address of the computer on the private network, not the public IP address. But this question is a duplicate. — Tim Biegeleisen, Apr 28 '15 at 10:59

There are some websites, that their sole piece of data is one line, which includes your public IP address.

Try something like:

URLConnection con = new URL("http://www.myipaddress.com").openConnection();
String ip = new BufferedReader(new 
                    InputStreamReader(con.getInputStream())).readLine();
