title: Pseudolocalization cannot find English (XA) in languages
body: <p>I am trying to use pseudolocalization as indicated in the official android documentation:</p>
  
  <p><a href="https://developer.android.com/guide/topics/resources/pseudolocales" rel="noreferrer">https://developer.android.com/guide/topics/resources/pseudolocales</a></p>
  
  <p>I follow each step:</p>
  
  <ul>
  <li>added <code>pseudoLocales true</code> in gradle file under debug buildconfig</li>
  <li>run the app</li>
  <li>go to settings -> languages</li>
  </ul>
  
  <p>but unfortunately I cannot find English (XA). Maybe I am missing something.</p>
