How to block a particular resource from loading in webview

Since API 11, there's WebViewClient.shouldInterceptRequest, here you can catch loading of embedded objects (images, etc) and replace it with your own image. For example:

WebResourceResponse wr = new WebResourceResponse("", "", new FileInputStream("/sdcard/aaa.jpg")); return wr; 

You must detect yourself what you want replace by what.

On API<11 it may be more complicated to achieve this (I don't know yet how).

You can remove any Element from the page by injecting JavaScript into a WebView. Below is an example of how to inject JavaScrpt into a WebView to remove an element having its id:

public void onLoadResource(WebView view, String url) { super.onLoadResource(view, url); // Removes element which id = 'mastHead' view.loadUrl("javascript:(function() { " + "(elem = document.getElementById('mastHead')).parentNode.removeChild(elem); " + "})()"); } 

You can use the below code to check whether to load it on not. Where webview is the object for WebView.

webview.setWebViewClient(new WebViewClient() { @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { // TODO Auto-generated method stub super.onPageStarted(view, url, favicon); Toast.makeText(activity,"onPageStarted url :"+url, Toast.LENGTH_LONG).show(); } @Override public void onLoadResource(WebView view, String url) { // TODO Auto-generated method stub super.onLoadResource(view, url); Toast.makeText(activity,"Connecting url :"+url, Toast.LENGTH_LONG).show(); } public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show(); } }); 

I think this will help you.
