            view.loadUrl(url);
            return true;
        }

It was very simple..also without using any javascriptInterface..In my code, Instead writing:

 wb.loadUrl("javascript:<script>   </script>");

use,

  wb.loadDataWithBaseURL(null,"<script>   </script>","text/html","utf-8",null);

and its working now :)
