title: CSipSimple where is the sip_home.xml file?
body: <p>In a quest to understand CSipSimple opensource app, I checked it out and compiled it successfully. However -> in the file SipHome.java of package com.csipsimple.ui, inside the onCreate() method:</p>
  
  <p>setContentView(R.layout.sip_home);</p>
  
  <p>The question is : where can I find sip_home.xml file ? I only found two files :</p>
  
  <p>1 - sip_home_one_pane.xml
  2 - sip_home_dual_pane.xml </p>
  
  <p>No sip_home.xml : what is going on ? how does the application decide how to load R.layout.sip_home ?</p>
