title: Connecting Android to a device with an Unknown UUID
body: <p>I want to connect my Tablet (with Android OS) to my Computer (with Ubuntu OS and Windows 8) but I don't know how to connect an Android Device to a Device with an Unknown UUID.</p>
  
  <p>I found <code>listenUsingRfcommOn, listenUsingInsecureRfcommOn, listenUsingEncryptedRfcommOn</code> in another <a href="https://stackoverflow.com/questions/13362774/android-listen-for-connections-without-uuid">Stackoverflow question</a> but I don't know what are those and how to use them. I've searched <code>listenUsingRfcommOn</code> in google and Android Developers Site but I got nothing. (Or at least I couldn't figure out if there was something useful or not).</p>
  
  <p>Does anyone know how can I connect them? And I want some explanation and useful links for those methods.</p>
  
  <p>Thanks.</p>
