title: How to use PJSIP on Android?
body: <p>I lost hours of searching and reading. I didnt really understand how to work with <a href="http://www.pjsip.org/" rel="noreferrer">PJSIP</a>. </p>
  
  <p>I have some questions about it:</p>
  
  <ol>
  <li>Can you explain how actually this library is used when developing for Android? </li>
  <li>When I build the library do I use only Java code or defintely I'll have to write in C++? </li>
  <li>My goal is encrypted VOIP Application for Android. </li>
  <li>Is there a good documentation with description of all methods, fields and constructors? </li>
  <li>Do you have any references to some tutorials or samples? </li>
  </ol>
