title: Host Unresolved Android
body: <p>In Android emulator I encounter "Connection is lost.Host is Unresolved" error while communicating with server (creating <code>websocket</code>) if <code>URL</code> string is used. instead if <code>IP address</code> and <code>port</code> number is used  it works fine. 
  I have configured it in host file of my <code>ubuntu powered pc</code>. It pings and all from the desktop.</p>
  
  <p>any ideas?</p>
