title: Lollipop notification background color
body: <p>I can't seem to make my notification use default notification background color: it remains gray where it should be white. At the same time, notification colors are appropriate in kitkat.</p>
  
  <p>I have implemented suggestions in <a href="https://stackoverflow.com/q/26960072/1760858">this question</a></p>
  
  <p>There doesn't seem to be any effect on what I implement. The values-v21 simply acts as if it weren't there.
  Naturally, my target sdk is 21. I just can't seem to find the reason for this.</p>
  
  <p>The notification is displayed from service using <code>StartForeground</code>. I have also tried <code>NotificationManager.notify()</code>, but it makes no difference.</p>
  
  <p>Also, the notification is gray even if I only leave the wrapper RelativeLayout in the xml:</p>
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                  xmlns:tools="http://schemas.android.com/tools"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"/&gt;
  </code></pre>
  
  <p>values-v21\styles.xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
    &lt;style name="NotificationText" parent="android:TextAppearance.Material.Notification" /&gt;
    &lt;style name="NotificationTitle" parent="android:TextAppearance.Material.Notification.Title" /&gt;
    &lt;style name="NotificationTime" parent="android:TextAppearance.Material.Notification.Time" /&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>Though these styles aren't used anywhere else (like in my app theme declaration). They are just defined (in values-v21 and values-v9).</p>
