<p>
  There are many situations where you might want your app to show a quick
  message to the user, without necessarily waiting for the user to respond.
  For example, when a user performs an action like sending an email or deleting
  a file, your app should show a quick confirmation to the user. Often the user
  doesn't need to respond to the message. The message needs to be prominent
  enough that the user can see it, but not so prominent that it prevents the
  user from working with your app.
</p>

<p>
  Android provides the {@link android.support.design.widget.Snackbar} widget
  for this common use case.
  A {@link android.support.design.widget.Snackbar} provides a quick pop-up
  message to the user. The current activity remains visible and interactive
  while the {@link android.support.design.widget.Snackbar} is displayed. After a
  short time, the Snackbar automatically dismisses itself.
</p>

<p>
  This class teaches you how to use {@link
  android.support.design.widget.Snackbar} to show pop-up messages.

<p class="note">
  <strong>Note:</strong> The {@link
  android.support.design.widget.Snackbar} class supersedes {@link
  android.widget.Toast}. While {@link android.widget.Toast} is currently still
  supported, {@link android.support.design.widget.Snackbar} is now the
  preferred way to display brief, transient messages to the user.
