title: Android chat using Smack API and talk.goolgle.com server
body: <p>I want to create an android chat application using smack api and <strong>talk.google.com</strong> server but the problem is that when I create a connection to Smack API using gmail id and password and check my user name using "connection.getuser()" my id is showm in following format "anything@gmail.com/Smack_<strong><em></strong>(some smack id)".Now if I send a message from my app using another phone to "anything@gmail.com" it is not recieved but if I send it to "anything@gmail.com/Smack</em><strong>_</strong>(same smack id)" it is properly recieved.</p>
  
  <p>The smack id being appended is random and changes everytime I connect so it is impossible for me to obtain it by any means and thus message cannot be sent,so how can I overcome this problem.</p>
  
  <p>The code for my ChatActivity is:</p>
