title: zxing embedded - setCaptureActivity() causes that the activity does not appear
body: <p>I tried to change zxing embedded scanner orientation from landscape to portrait.</p>
  
  <p>I found an example how to do it in <a href="https://github.com/journeyapps/zxing-android-embedded/blob/master/README.md#changing-the-orientation" rel="nofollow">ZE readme on github</a>. But the line</p>
  
  <pre><code>integrator.setCaptureActivity(CaptureActivityAnyOrientation.class);
  </code></pre>
  
  <p>causes that the Activity is not even displayed. Without the line it works great except the portrait orientation. This code works with version 3 and higher and I use version 3.0.2.</p>
  
  <p>Does anybody have the same problem?</p>
