title: Android - Snackbar vs Toast - usage and difference
body: <p>We have been using just Toasts in our application so far and as we are planning to adopt some new features from Support Design Library I am wondering what's the recommended usage for Snackbar vs. Toast.</p>
  
  <p>I have been reading on <strong><em><a href="https://material.io/design/components/snackbars.html#" rel="noreferrer">the google material snackbar doc.</a></em></strong></p>
  
  <blockquote>
    <p>Snackbars provide lightweight feedback about an operation in a small
    popup at the base of the screen on mobile and at the lower left on
    desktop. They are above all over elements on screen, including the
    FAB.</p>
  </blockquote>
  
  <p>and toasts.</p>
  
  <blockquote>
    <p>Android also provides a capsule-shaped toast, primarily used for
    system messaging. Toasts are similar to snackbars but do not contain
    actions and cannot be swiped off screen.</p>
  </blockquote>
  
  <p>I understand what they do but I am a bit confused when to use what. Does it mean that:</p>
  
  <ul>
  <li>If I don't require user interaction I would use a toast?</li>
  <li>What is meant by "system messaging"? Does that apply to displaying information when something important happened between my app and the Android system?</li>
  <li>What I like is the swipe off screen feature - would that be a reason to start replacing toasts with snackbars? (this is a bit opinion based question though)</li>
  </ul>
