Difference util.Geolocation and device.Geolocation plus GPS Problem

[clifficious]

Hi there,

I was wondering what the difference is between util.Geolocation and device.Geolocation. I tried coding a little example but the output seems to be the same. Also as there is still the bug of not getting the high Accuracy (GPS module) running, I tried using the workaround presented here.

Here is my sample code...

geo = Ext.create('Ext.util.Geolocation', {
        autoUpdate: true,
        allowHighAccuracy: true,
        frequency: 3000,
        timeout: 30000,
        listeners: {
            locationupdate: function(geo) {
                var map = Ext.getCmp('map');
                latlon = new google.maps.LatLng(geo.getLatitude(), geo.getLongitude());

                marker = new google.maps.Marker({
                    position: latlon,
                    map: map.getMap()
                });
            },
            locationerror: function(geo, bTimeout, bPermissionDenied, bLocationUnavailable, message) {
                if(bTimeout){
                    alert('Timeout occurred.');
                } else {
                    alert('Error occurred.'+message);
                }
            }
        }
    });

and

watchID = Ext.device.Geolocation.watchPosition({
    frequency: 3000, 
    timeout: 30000,
    allowHighAccuracy: true,
    callback: function(position) {
        var map = Ext.getCmp('map');
        latlon = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
        map.getMap().setCenter(latlon);
 
        marker = new google.maps.Marker({
            position: latlon,
            map: map.getMap(),
            icon : "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=•|117569"
        });

    },
    failure: function(e) {
        console.log('something went wrong!');
        console.log(e);
    }
});

There seems to be no difference when using the methods. Also when using it with PhoneGap the GPS is not accessed correctly. After applying the work-around the GPS symbol pops up for less than a second but than vanishes again. After 3 seconds (the frequency) the same happens again. GPS sign blinks and vanishes.
Can anybody help me in this issue? Or support me with some working code? Im currently testing it on a Google Nexus phone running Android 4.0.4.

Thanks guys!
Cliff

Ext.util.Geolocation uses the HTML5 Geolocation. Ext.device.Geolocation uses the device's GPS is it is using the native wrapper else it will use Ext.util.Geolocation

in my testapp which I used together with PhoneGap using this tutorial (which is similar to the one for iOS) both method have the same output. But after changing the order of the JS-sources and putting the cordova.js infront of sencha.js I got the error which is thrown because

src/device/geolocation/PhoneGap.js

is not available. It is referenced in device/Geolocation.js in line 54. Looking into the directory it is really missing.

Is there any reason for this? It seems that Sencha does not have any chance of activating the PhoneGap GPS system.

After changing

Ext.device.Geolocation.watchPosition

in my code to

navigator.geolocation.watchPosition

and commenting out line 54 in devices/Geoloction.js I got the device's GPS module working.

Ext.device.Geolocation is not initialized, is it?
