title: React native blank screen after generating APK
body: <p>I'm using react-native, and everything was working well while I was developing, but, when I built the APK (using this tutorial: <a href="https://facebook.github.io/react-native/docs/signed-apk-android.html#content" rel="nofollow">https://facebook.github.io/react-native/docs/signed-apk-android.html#content</a>) and installed it on my device, the app shows just a blank page.<br>
  Did anybody had the same issue?</p>
  
  <p>Edit:<br>
  I looked at the log on the device, and this is the error:  </p>
  
  <blockquote>
