title: Keyboard aware scroll view Android issue
body: <p>I've created a react native project using Expo XDE (xde-2.19.3) with a few <code>TextInputs</code> on the screen. Im using <code>KeyboardAwareScrollView</code> to scroll the inputs from under the keyboard into view and works fine on iOS but does not work on Android. Hope that makes sense.</p>
  
  <p>Looked at the <code>KeyboardAwareScrollView</code> docs and saw that I need to configure <code>AndroidManifest.xml</code> but it seems that Expo has already sorted this out: <a href="https://github.com/expo/expo/blob/master/template-files/android/AndroidManifest.xml" rel="noreferrer">https://github.com/expo/expo/blob/master/template-files/android/AndroidManifest.xml</a></p>
  
  <p>However I'm still not able to get this working on Android... </p>
  
  <p>What could I be missing?</p>
