    You should use webview client to intercept the clicks.

    Code :

    In your webview set webViewClient

    webView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            String url = request.getUrl().toString();
            if (isValidEmail(url)) {
                return true;
            } else if (url.contains("www.instagram.com"))
                return true;
            else if (url.contains("https://t.me"))
                return true;
            else
                return super.shouldOverrideUrlLoading(view, request)
        }

        @Override
        public void onLoadResource(WebView view, String url) {
            // do nothing
            //super.onLoadResource(view, url);
        }
    });

    To check whether it’a valid email :

      public static boolean isValidEmail(CharSequence target) {     return (!TextUtils.isEmpty(target) && Patterns.EMAIL_ADDRESS.matcher(target).matches());
 }

    Now in shouldOverrideUrlLoading you can check the url and return whether to override url loading or not according to your need.
