title: Android Fonts in XML not working on 7.0
body: <p>Hello everyone,
                 I have used <a href="https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml.html#using-support-lib" rel="nofollow noreferrer">Fonts</a> in xml for my app. It's working very well on android versions below 7.0. But not working on 7.0. I created a font folder inside drawable and put all my fonts in there. Then created a font family like this. </p>
  
  <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;font-family xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
      &lt;font
          android:font="@font/timeburnerbold"
          android:fontStyle="normal"
          android:fontWeight="400"
          app:font="@font/timeburnerbold"
          app:fontStyle="normal"
          app:fontWeight="400" /&gt;
      &lt;font
          android:font="@font/typo_grotesk_bold"
          android:fontStyle="normal"
          android:fontWeight="700"
          app:font="@font/typo_grotesk_bold"
          app:fontStyle="normal"
          app:fontWeight="700" /&gt;
  &lt;/font-family&gt;
  </code></pre>
  
  <p>My Gradle file info</p>
  
  <pre><code>compileSdkVersion 27
  buildToolsVersion "26.7.2"
  supportLibraryVersion = '27.0.0'
  </code></pre>
  
  <p>And I m using this across the app. It's working perfectly across the app on 6.0 and below. But not on 7.0. Don't know what I m missing here. Anyone?</p>
