title: fontFamily in FragmentActivity doesn't work
body: <p>I created a simple dummy project in Android Studio 3.5.1 with 2 activitites. You can download it here: <a href="https://drive.google.com/open?id=1OXlyjk_NYHLQLa3uxw_twE4A5CkBLtEr" rel="nofollow noreferrer">https://drive.google.com/open?id=1OXlyjk_NYHLQLa3uxw_twE4A5CkBLtEr</a></p>
  
  <p>One activity is AppCompatActivity, the second one is FragmentActivity. Both activities contain TextView with android:fontFamily set to a new font.</p>
  
  <p>When launched, AppCompatActivity's TextView uses that new font, but the FragmentActivity's TextView still uses default font.</p>
  
  <p>Should I report this as a bug? Or is this a bad way to set fontFamily? Can you please show me a reliable way how to set fontFamily for textView inside FramgmentActivity.</p>
