title: Android WebView- PopUp background is Transparent
body: <p>I have loaded a WebView in my android app:</p>
  
  <pre><code>webView = (WebView)view.findViewById(R.id.webView);
  String url = UrlConstants.URL_CITY;
  webView.getSettings().setJavaScriptEnabled(true);
  webView.loadUrl(url);
  
  webView.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
    view.loadUrl(url);
    return true;
  }
  </code></pre>
  
  <p>But every popUp that is of the website has a transparent background  as shown:
  <img src="https://i.stack.imgur.com/VMfHb.png" alt="PopUp with transparent background"></p>
  
  <p>I've tried many urls as well: <a href="http://www.topuniversities.com/universities/insead-france/undergrad" rel="nofollow noreferrer">One being this</a></p>
  
  <p>Anyone help will be appreciated. Thanks</p>
