    <p>Action Bar</p>
  </div>
</a>

<p>The action bar is one of the most important design elements you can implement for your
app's activities. It provides several user interface features that make your app immediately
familiar to users by offering consistency between other Android apps. Key functions include:</p>

<ul>
  <li>A dedicated space for giving your app an identity and indicating the user's location
  in the app.</li>
  <li>Access to important actions in a predictable way (such as Search).</li>
  <li>Support for navigation and view switching (with tabs or drop-down lists).</li>
</ul>
