title: Using OKHttp, what is the difference between synchronous request in AsyncTask and OKhttp Asynchronous request?
body: <p>OKHttp supports both <a href="https://github.com/square/okhttp/wiki/Recipes">synchronous and asynchronous api</a>. 
  If I want to issue an async request, I can:</p>
  
  <ol>
  <li>Use a AsyncTask, and issue OKhttp synchronous api.</li>
  <li>Issue a OKhttp asynchronous api.</li>
  </ol>
  
  <p>What is the difference between these 2 options? And which one is better?</p>
