title: What is the difference between launch app from "recent apps" and tapping app icon
body: <p>I'm working on large project, so there is some logic for saving application state, and then opening correct activity(fragment) when it comes from background. 
  But anyway, I've found that if user navigates through my app and then minimize it - android opens it from background in different ways in following cases:</p>
  
  <ol>
  <li><strong>User taps on app icon</strong> (behavior: user see home activity, doesn't matter where he was, when application was minimized) </li>
  <li><strong>User select app from android "recent apps"</strong> (behavior: user see exactly what he saw, when the application was minimized)</li>
  </ol>
  
  <p>So, what is the difference between launching application from background by this two ways? I always thought, that it is the same mechanism, but, obviously, I was wrong. </p>
  
  <p>Thanks for any answers </p>
