title: Stop WebView rendering until the page is fully-loaded
body: <p>I'm working on an app that is using WebView. Unfortunately, when user clicks a link, when the page is loading, the whole WebView area "blinks" until its loading is complete. There's also 1 more problem with it - I'm using a JavaScript that reverses colors of the page at the end of its loading - so until it's fully-loaded, the colors are normal, so again - blinking.</p>
  
  <p>So, what I wannna do is "stop" rendering of the WebView, until the page is completely loaded - then, resume the rendering, so it won't blink. How to do that?</p>
  
  <p>Note: I don't want to modify the webpage to achieve what I want. I have to modify WebView behavior.</p>
  
  <p>And one more note, because it's maybe not clear: by "stop rendering" I mean "display currently rendered page continually until the new one is fully loaded" :)</p>
