Android Webview - Intercept Clicks

Android WebView - Intercept clicks

Then you have to set a WebViewClient to your WebView and override shouldOverrideUrlLoading and onLoadResource methods. Let me give you a simple example:

WebView yourWebView; // initialize it as always...
// this is the funny part:
yourWebView.setWebViewClient(yourWebClient);

// somewhere on your code...
WebViewClient yourWebClient = new WebViewClient(){
    // you tell the webclient you want to catch when a url is about to load
    @Override
    public boolean shouldOverrideUrlLoading(WebView  view, String  url){
        return true;
    }
    // here you execute an action when the URL you want is about to load
    @Override
    public void onLoadResource(WebView  view, String  url){
        if( url.equals("http://cnn.com") ){
            // do whatever you want
        }
    }
}

How to intercept link requests in a webView?

This can be achieved by setting the webviewclient eg.

mWebView.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url.startsWith("http://blablablacatchurl")) {

            //we have intercepted the desired url call
            return true;
        }

        return super.shouldOverrideUrlLoading(view, url);
    }
});

If you want to see if there is a way to deep link to the facebook app, just package the url in an intent and fire it off and see what responds. If facebook doesn't catch it I don't think you can perform the second part of your request in any other way.

Android WebView URL intercept , i want to load only one website and it's pages , and nothing else

In both cases you have consumed the event. try something like below .

 webView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            if (request.getUrl().equals(host)) {
               // Intercept URL Load url here return true if url is consumed  
                return true;
            }
            return super.shouldOverrideUrlLoading(view, request);
        }
    });

Or if you want to block all other links then you can use it like below .

 webView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            if (request.getUrl().equals(yourwebsite)) {

                return super.shouldOverrideUrlLoading(view, request);
            }
            return true;
        }
    });

Keep that in mind that all other links will not work so this can be a bad impression on your app . So i suggest that you should open other links with a browser intent . Like below.

 webView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            if (request.getUrl().equals(yourwebsite)) {

                return super.shouldOverrideUrlLoading(view, request);
            }else{
                try {
                    Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(request.getUrl()));
                    startActivity(browserIntent);
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
            return true;
        }
    });

NOTE:- This is implementation for shouldOverrideUrlLoading(WebView view, WebResourceRequest request) which is applicable above API 21 . So you should also override shouldOverrideUrlLoading(WebView view, String url) for previous version in same way .
