I want to remove the header of the website in android 'WebView'. With the Code that I have, it works. But the problem is that the 'WebView' is removing the header after the page loaded completely. I want to remove it, while it is loading.

Thats the code snippet:

webView.setWebViewClient(new WebViewClient() {

            @Override

            public void onPageFinished(WebView view, String url)

            {

                webView.loadUrl(javascript:(function() {  +

                        var head = document.getElementsByTagName('header')[0];

                        + head.parentNode.removeChild(head); +

                        })());



                webView.loadUrl(javascript:(function() {  +

                        var head = document.getElementsByTagName('footer')[0];

                        + head.parentNode.removeChild(head); +

                        })());

            }

        });

Easiest way is to inject Javascript in onLoadResource() method. Put it inside try-catch block since WebView will not know about the element before it has been loaded:

webView.setWebChromeClient(new WebChromeClient() {

           ...



            @Override

            public void onLoadResource(WebView view, String url) {



                try {

                    webView.loadUrl(javascript:(window.onload = function() {  +

                            (elem1 = document.getElementById('id1')); elem.parentNode.removeChild(elem1);  +

                            (elem2 = document.getElementById('id2')); elem2.parentNode.removeChild(elem2);  +

                            })());

                } catch (Exception e) {

                    e.printStackTrace();

                }



            }

}
