if the url changes then use shouldOverrideUrlLoading with some regex

so

List<String> validUrls = new LinkedList<>();
validUrls.add("https://www\\.google\\.com/*");
validUrls.add("https://www\\.facebook\\.com/*");


@Override public boolean shouldOverrideUrlLoading(WebView view, String url) {
    if (isValidUrl(url)) {
        return false;
    }
    return true;
}

private boolean isValidUrl(String url) {
    for (String validUrl : validUrls) {
        Pattern pattern = Pattern.compile(validUrl, Pattern.MULTILINE);
        Matcher matcher = pattern.matcher(url);
        if (matcher.find()) {
            return true;
        }
    }
    return false;
}

would match against any www.google.com or facebook.com urls

You can intercept the urls that are opened from the webview, I don't know if it would work with the popup:

    WebViewClient client= new WebViewClient(){
        @Override 
        public boolean shouldOverrideUrlLoading(WebView  view, String  url){
           if (url.equals("popupURL"){ 
                return true; 
           }
            return false;
        } 
    } 

webView.setWebViewClient(client);
