HI, try this..in your webview.

    mWebView.setWebChromeClient(new WebChromeClient() {

        // this will be called on page loading progress

        @Override

        public void onProgressChanged(WebView view, int newProgress) {

            super.onProgressChanged(view, newProgress);


            loadingProgressBar.setProgress(newProgress);

            // hide the progress bar if the loading is complete

            if (newProgress == 100) {

                loadingProgressBar.setVisibility(View.INVISIBLE);

            } else {

                loadingProgressBar.setVisibility(View.VISIBLE);

            }

        }

    });

Thanks for the suggestion but its giving me errors and Force to close in android . In the code i have import class but still there are errors on setVisibility(View.VISIBLE) so any other solution – umar Feb 09 '11 at 17:36
in your layout did you add progressbar ? and in Activity did you declare and initialize progressbar with xml resource id ? then it wont give you error. this is my working code. – Ganapathy C Feb 09 '11 at 17:48
