  • it's not working...actually here I have crawl some info using asyncTask background method and returning String html data ...and then these data just displaying adding into webView to display the content based on html ... – Abdul Rizwan May 19 '15 at 10:43
  • did you tried clearing cache after webview is loaded ? `AsyncTask` is asynchronous therefore, clearing cache during page load will not work – Jibran Khan May 19 '15 at 10:46
  • Print your result in logCat and see, it may be null, thats why your code is not running and showing previous data. – Assad May 19 '15 at 10:49
  • I have printed in log cat...it's displaying the different info based on my search...but in webview some time it's displaying previous data...its not displaying as it's displaying in logCat... – Abdul Rizwan May 19 '15 at 11:42
