title: Android TV webview loading
body: <p>I have an android tv 'wrapper' that will load a webapp using webview. It all loads fine using <code>webview.loadUrl('someurl')</code> but whilst the page is loading, it's just a grey background. </p>
  
  <p>What I wanted to do was first load a static file - which shows a loading spinner, and then load the main application, but doing this still makes the screen grey whilst the main app is loading. </p>
  
  <p>Is there a simple way to either spin up a second webview ( seems wasteful ) - or to load one url (the file) and then the main remote url? </p>
