title: Using the Material Theme colorPrimary status bar won't change
body: <p>So I set in my theme:</p>
  
  <pre><code>&lt;item name="colorPrimaryDark"&gt;@color/indigo_50&lt;/item&gt;
  </code></pre>
  
  <p>nothing has changed , why?</p>
  
  <p>I know that:</p>
  
  <pre><code>On older platforms, AppCompat emulates the color theming where possible. At the moment this is limited to coloring the action bar and some widgets.
  </code></pre>
  
  <p>but:
  In this application works without problems:</p>
