title: How to use 'apple system font' in android application
body: <p>We developed an application in IOS using 'apple-system-font' and we loved this font so we want to use the same font for all TextViews in the android application.
  So Is there any way to use 'apple-system-font' in the android application like the following:</p>
  
  <pre><code>&lt;TextView
      ...
      android:fontFamily="-apple-system-font" /&gt;
  </code></pre>
