   I've applied this source code to perform call recording but It's not recording call (Two Way Recording). </p>
  
  <p>After searching a lot I've got android have banned call recording service after version 4.1. But there is an <a href="https://play.google.com/store/apps/details?id=polis.app.callrecorder" rel="nofollow noreferrer">CallRecorder App</a> on google play which is working fine in my mobile too. </p>
  
  <p>How can I perform call recording feature in my app?</p>
