title: Set Locale from App - Back Button Issue
body: <p>I am working on Language setting on my app. I was able to change the locale from my Main Activity through the use of </p>
  
  <pre><code>Resources resources = getResources();
  Configuration configuration = resources.getConfiguration();
  DisplayMetrics displayMetrics = resources.getDisplayMetrics();
  configuration.setLocale(new Locale("ar"));
  resources.updateConfiguration(configuration,displayMetrics);
  recreate();
  </code></pre>
  
  <p>Everything worked fine but I noticed that the back button did not change its direction to RTL:</p>

  <p>This is my expected behaviour when I set the language to a RTL language:</p>

  <p>Is this possible?</p>
