If the links contain geographic locations, phone numbers, and email addresses, you can switch to the search screen and mail client using the code below.

public boolean shouldOverrideUrlLoading(WebView view, String url) {
    if (url.startsWith("tel:")) {
        Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
        startActivity(intent);
        view.reload();
        return true;
    } else if (url.contains("mailto:")) {
        view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
        return true;
    } else if(url.contains("geo:")) {
        view.getContext().startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse(url)));
        return true;
    } else {
        view.loadUrl(url);
        return true;
    }
}
