title: Creating TCP connection from server to android device
body: <p>I'm trying to create tcp connection between server and android device.</p>
  
  <p>I managed to create it when the server (my computer) and the android device were connected to the same router (same local network).</p>
  
  <p>When I connect the device to mobile internet, and try to create tcp connection from the server to the new ip device (which I get by whatismyip.com etc.), it doesn't work..</p>
  
  <p>I guess the problem is wrong IP address, but how can I get the correct ip device? (if it is the problem)</p>
