title: Problems understanding NsdChat sample app
body: <p>I'm not sure I understand how this android sample works (NsdChat found in developer.android Tutorials).</p>
  
  <p>My first idea was to run 2 istances of the App (with 2 instances of Eclipse on the same machine) and try make them communicate but, it doesn't seem to work: I can't figure out if registration and discovery buttons works and while trying to send a message from 1 to another the destination App show nothing and the Eclipse console of BOTH istances show "Client sent message:test", why?</p>
  
  <p>Maybe I haven't completely understood how the example works. Can someone explain to me how to execute and understand this sample?</p>
