title: Refused to display a frame because it set X-Frame-Options to 'DENY in android webview
body: <p>When I try to show the google calendar in webview , it show some error:</p>
  
  <pre><code>[INFO:CONSOLE(0)] "Refused to display 'https://accounts.google.com/ServiceLogin?service=cl&amp;passive=1209600&amp;continue=https://www.google.com/calendar/embed?src%3Detlwhk@gmail.com%26ctz%3DAsia/Hong_Kong&amp;followup=https://www.google.com/calendar/embed?src%3Detlwhk@gmail.com%26ctz%3DAsia/Hong_Kong&amp;btmpl=mobile&amp;ltmpl=mobilex&amp;scc=1' in a frame because it set 'X-Frame-Options' to 'DENY'.", source: about:blank (0)
  </code></pre>
  
  <p>And this is the html code</p>
  
  <pre><code>&lt;p&gt;&lt;iframe style="border: 0;" src="https://www.google.com/calendar/embed?src=etlwhk%40gmail.com&amp;amp;ctz=Asia/Hong_Kong&amp;amp;output=embed" width="800" height="600" frameborder="0" scrolling="no"&gt;&lt;/iframe&gt;&lt;/p&gt;
  </code></pre>
  
  <p>And for the android side it is some simple webview code</p>
  
  <pre><code>        StringBuilder sb = new StringBuilder();
          sb.append("&lt;HTML&gt;&lt;HEAD&gt;&lt;meta name='viewport' content='width=device-width, initial-scale=1.0, maximum-scale=1.0'&gt;&lt;style&gt;img{display: inline; height: auto; max-width: 100%}iframe{width:100%}&lt;/style&gt;&lt;/HEAD&gt;&lt;body&gt;");
          sb.append(page.page_content_chi.toString());
          sb.append("&lt;/body&gt;&lt;/HTML&gt;");
          webview.loadDataWithBaseURL("file:///android_asset/", sb.toString(), "text/html", "utf-8", null); 
  </code></pre>
  
  <p>How to fix the error? Thanks for helping.</p>
