Add isMobile() method to Request class?

[wyz]

Hi, during my development with Play, I found it is good to add
isMobile() method to Request class, so we can detect whether user is
accessing from mobile browser or from desktop browser.

Thanks.

maybe something more generic would be more better ?
because we could have isTablet(), isBionicEye(), isBionicLeg(), isBionicArm() at the end...

Something that detect browser features would be more reliable, a la jQuery.

Browser features on the server side?

[Federico Tolomei]

It would be based on the User-Agent. Other frameworks to this, see [0] and [1].
I notice that ASP.NET have IsMobileDevice property :-)

The user agent doesn't tell you what browser features are available.

Of course not directly. Those capability detector using pre-written
file (i.e. browsercap.ini in .NET/Mono). The User-Agent tells which
browser the client is using then some code loads a data structure with
property values for that User-Agent. See [0] [1]. Write a browsercap
can be complex task: Mono's browsercap is 16k rows and it is rather
complete (i.e. Emacs browser, zillion of crawlers...)

Hi

Sounds interesting

It wouldn't be too hard to propose a simple Java API
that takes a User-Agent String and returns a set of helpers
for instance.

Here is how I redirect my visitors on express-board.fr to a specific
controller when I detect iPhone :

public static void index() {
// some code removed here
// ........

Http.Header header = Http.Request.current().headers.get("user-agent");
if(header==null){
// this happens usually due to PHP security-break detector
robots that tries to
// find bugs on web site... yes it sucks I know
return;
}
if (header.value() == null) {
// drop bad client
return;
}

String headerValue=header.value().toLowerCase();

if (headerValue.contains("iphone")) {
redirect("IPhone/index");
return;
}

// ... some more code

}
