title: Task and Activity stack : what is difference between both.
body: <p>I followed some tutorials but got confused with "Activity stack" and "Task". </p>
  
  <ul>
  <li>Because both starts when a new activity is created.</li>
  <li>Activity stack keeps a navigation history of activities, and Task is a sequence of activities.</li>
  </ul>
  
  <p>Is this is only difference that Activity stack made up of one or more task(S)? </p>
  
  <p>Give some example please. </p>
