Android – How to create a link for all mobile devices that opens google maps with a route starting at the current location, destinating a given place

I rather thought this would not be so hard to find out but appearantly it is not easy to find an awesome cross device article, like you'd expect.

I want to create a link which opens either the mobile device's browser and surf to google maps OR open a maps app (Apple Maps or Google Maps) and directly starting a route, i.e.: start at the current location, end at a given point (lat/long).

I can test on two devices (beside browserstack), an Android and an iPhone.

The following link works only on the Android:

<a href="http://maps.google.com/maps?daddr=lat,long&amp;ll=">Take me there!</a>

Clicking this link in iPhone's Chrome, this weirdly opens Google Maps in desktop version with ads on the mobile app…

This one only works on iOS, opening Apple Maps asking me to enter a start location (i can pick "Current Location") and start the route = desired behavior. Clicking this link completely fails on Android:

<a href="maps://maps.google.com/maps?daddr=lat,long&amp;ll=">Take me there!</a>

Notice the maps:// protocol.

Is there an elegant cross device way of creating such a link? One link that works on all main mobiles?

Thanks

UPDATE: Solution found (kinda)

Here is what I've come up with. It's not quite what I imagined, though it's working.

var ua = navigator.userAgent.toLowerCase(),
    plat = navigator.platform,
    protocol = '',
    a,
    href;

$.browser.device = ua.match(/android|webos|iphone|ipad|ipod|blackberry|iemobile|opera/i) ? ua.match(/android|webos|iphone|ipad|ipod|blackberry|iemobile|opera/i)[0] : false;


if ($.browser.device) {
    switch($.browser.device) {
        case 'iphone':
        case 'ipad':
        case 'ipod':
            function iOSversion() {
              if (/iP(hone|od|ad)/.test(navigator.platform)) {
                // supports iOS 2.0 and later: <http://bit. ly/TJjs1V>
                var v = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/);
                return [parseInt(v[1], 10), parseInt(v[2], 10), parseInt(v[3] || 0, 10)];
              }
            }

            var ver = iOSversion() || [0];

            if (ver[0] >= 6) {
              protocol = 'maps://';
            }
            else {
                protocol = 'http://maps.google.com/maps';
            }
        break;

        case 'android':
        default:
            protocol = 'http://maps.google.com/maps';
        break;
    }

a.attr('href', protocol + href)

the maps:// protocol is the url scheme for the apple maps app, which will only start working on ios 6 or higher. There are ways to test if gmaps is installed and then chose what to do with the url, but that was kind of too much for what I intended. So i just ended up creating a maps:// OR maps.google.com/ link, using the above parameters.

** UPDATE **

sadly, $.browser.device don't work since jquery 1.9
