title: How to switch from Surface View (running in an activity) to other activity
body: <p>In one of scenario, I have implemented Surface View which is part of an Activity. Now I need to hide this Video view so can roam in other screen of application.</p>
  
  <p>AFAIK, we can't minimise/hide Activity, what could be other approach to handle such scenario.</p>
  
  <p>I come across Hangout &amp; WhatsApp Video calling scenario, they hide video view while move back to other activity &amp; resume when need. </p>
  
  <p>I also come across Youtube mobile application, but they might be managing everything in single activity. Also found some solution available <a href="https://github.com/pedrovgs/DraggablePanel" rel="nofollow noreferrer">here</a>. &amp; <a href="http://flavienlaurent.com/blog/2013/08/28/each-navigation-drawer-hides-a-viewdraghelper/" rel="nofollow noreferrer">here</a>. I still need to try.</p>
  
  <p>How they do. Any suggestion !</p>
