title: How can I execute Javascript on already loaded webpage in Android Webview
body: <p>I want to execute a javascript on already loaded webpage in Webview. I
  am loading a new article webpage eg: www.techcrunch,com in webview. I
  want to run javascript on this already loaded webpage in Webview. This
  javascript is an external file in assets folder. The javascript
  basically extracts images from the  tags in does some other
  processing in the html page. How can I execute this javascript on the
  already loaded www.techcrunch.com page?</p>
  
  <p>Thanks,</p>
