I need to block some URLs that store in file on /res/raw/ from loading in webview.

method of the WebViewClient

Give the host application a chance to take over the control when a new url is about to be loaded in the current WebView.If WebViewClient is provided, return true means the host application handles the url, while return false means the current WebView handles the url.

in code:

    public class MyWebViewClient extends WebViewClient {
    public boolean shouldOverrideUrlLoading (WebView view, String url) {
        if (Uri.parse(url).getHost().equals("http://Your_website_url")) {
             // This is my web site, so do not override; let my WebView load the page
             return false;
        }

        // reject anything other
        return true;
    }
}


mWebview.setWebViewClient(new MyWebViewClient());  //set the webviewClient

You have to override the method shouldOverrideUrlLoading (see here) of your WebViewClient, rather than the one you are overriding. Just return false if you want to load the page; true if you want to block loading.

good but in this case how can block a list of site's within the file – Mike jess Mar 18 '17 at 10:23
You have to implement the logic. Load the list inside of a List and then check that list in shouldOverrideUrlLoading – Massimo Mar 18 '17 at 10:25
