Vaadin-14: checking if client is a mobile device

i am developing a webapp and i want to separate UIs for desktops and mobile devices, so i want to check wether the client using my app is a mobile device or not.

I tried to look online for official documentation or vaadin forum , but i couldn't find any useful information, since almost all of the solutions proposed in those answers are not implementable any more (the methods were removed).

If anyone is interested i found a way around CSS, even if i think it's a bit limited.

I used HttpServletRequest, VaadinService and VaadinServletRequest: I basically checked if words like "Mobile", "iPhone" or "Android" are in the request.

It's not an elegant solution, but it works. This is the code:

public static boolean isPhone(HttpServletRequest request) {
    String url = request.getHeader("User-Agent");
    return (url.contains("iPhone") || url.contains("Android"));
}

You can use VaadinSession.getCurrent().getBrowser() to see if your client is a phone or not.

public  boolean isMobileDevice() {
    WebBrowser webBrowser = VaadinSession.getCurrent().getBrowser();
    return webBrowser.isAndroid() || webBrowser.isIPhone() || webBrowser.isWindowsPhone();
}
