title: Webview on Amazon Fire Stick not responding to controller
body: <p>I've got an Android app in Cocos2d-x that uses a WebView to display the front end menu.  Currently it's just a mock-up, and just has a URL to a website, which makes it easy to test.</p>
  
  <p>If I load the URL of the interface in the Amazon Web App Tester on an Amazon Fire TV stick it works perfectly, and you can navigate the interface happily with the controller.</p>
  
  <p>However, when I load the app on the stick, which shows the same URL in a WebView component then the controller has no effect and doesn't navigate (or even highlight) the interface.</p>
  
  <p>How can I get the WebView to behave like the web view in the tester app, and respond to the controller?  </p>
