title: Changing Font restarts activity
body: <p><code>Activity</code> is getting restarted when system font is changed while app is running.</p>
  
  <p>Is there any way I can avoid restarting of my <code>Activity</code>?
  I tested it with basic <strong>"Hello World"</strong> application.</p>
  
  <p>I am using Android 4.1 as target</p>
  
  <p>PS: I have tried using <code>android:configChanges</code> but there wasn't any flag related to font change.</p>
