Answer 1

    webView.setWebViewClient(new myWebClient()); 
// add this while initializing webview


// then do add following code





public class myWebClient extends WebViewClient {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
           // super.onPageStarted(view, url, favicon);
            if (Uri.parse(url).getHost().contains("https://qa.mstitute.com/test/build/#!/")) {
                // This is my web site, so do not override; let my WebView load the page
                Log.d("web","block");

            }else{
                super.onPageStarted(view, url, favicon);
            }

            Log.d("web","Started");
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            // TODO Auto-generated method stub

            if (Uri.parse(url).getHost().equals("https://qa.mstitute.com/test/build/#!/")) {
                // This is my web site, so do not override; let my WebView load the page
                Log.d("web","block");
                return false;
            }else {
                view.loadUrl(url);
                return true;
            }

        }
        @Override
        public void onReceivedError(WebView view, WebResourceRequest request,
                                    WebResourceError error) {
            super.onReceivedError(view, request, error);
            Log.d("web","got an error");

        }
        @Override
        public void onPageFinished(WebView view, String url) {
            // TODO Auto-generated method stub





        }
    }

Answer 2

this will cause nothing to happen when the link "http://www.myweb.com/pepito" is clicked

public class MyWebViewClient extends WebViewClient {
    public boolean shuldOverrideKeyEvent (WebView view, KeyEvent event) {
         // Do something with the event here
         return true;
    }

    public boolean shouldOverrideUrlLoading (WebView view, String url) {
        return url.equals("http://www.myweb.com/pepito");
    }
}

Answer 3

shouldOverrideUrlLoading will examine the web page URL loaded into the WebView and all URLs loaded within the page content.

public class MyWebViewClient extends WebViewClient {
    public boolean shouldOverrideKeyEvent (WebView view, KeyEvent event) {
         
         return true;
    }

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

        // Reject everything else.
        return true;
    }
}
