title: Preload fragment's webview in ViewPager on first run
body: <p>Ok, so similar questions have been asked, but after trawling SO and google for a day I still can't find an answer to this.</p>
  
  <p>I have a ViewPager loaded with fragments via a pagerAdapter, set up to swipe between the views.</p>
  
  <p>Each fragment has just one WebView</p>
  
  <p>Each webview's html contains a coloured 'body' tag, let's say green.</p>
  
  <p>Also the html contains a full-size image.</p>
  
  <p>When the pages are swiped, the green body of the page is displayed straight away, but there is a flash while the image loads, implying the image is loaded as the page is viewed.</p>
  
  <p>Once the page has been visited then it scrolls to smoothly, with no wait for the image load.</p>
  
  <p>I've tried setOffscreenPageLimit(3) and setOffscreenPageLimit(fragments.size()), but these only have effect on the retention of pages once they've been visited, not on what is loaded at creation time.</p>
  
  <p>Is there any way to pre-load the web pages and their content on creation of the ViewPager and fragments?</p>
  
  <p>Seems strange if there's no answer to this.</p>
