Question

As an example I implemented a method wich shows me all the geolocation stuff.

    function showLocation() {
    navigator.geolocation.getCurrentPosition(onGeoSuccess, onGeoError);
}

        function onGeoSuccess(position) {
    var element = document.getElementById('geolocation');
    element.innerHTML = 'Latitude: '           + position.coords.latitude              + '<br />' +
                        'Longitude: '          + position.coords.longitude             + '<br />' +
                        'Altitude: '           + position.coords.altitude              + '<br />' +
                        'Accuracy: '           + position.coords.accuracy              + '<br />' +
                        'Altitude Accuracy: '  + position.coords.altitudeAccuracy      + '<br />' +
                        'Heading: '            + position.coords.heading               + '<br />' +
                        'Speed: '              + position.coords.speed                 + '<br />' +
                        'Timestamp: '          + new Date(position.timestamp)          + '<br />';
}

so I took a walk arround the block pressing this button:

<input type="submit" data-theme="d" name="login" id="login" value="Position" onclick="showLocation()"/>

However, the Attributes for Altitude, Heading and Speed always shows null.
Altitude Accuracy also shows null, but the phonegap docu says it´s not working with android. So why is this not working?
thanks in advance, Daniel

dev.w3.org/geo/api/spec-source.html#coordinates_interface

it might be device specific, as to whether or not those parameters are supported “If the implementation cannot provide {those variables you’re having trouble with} information, the value of this attribute must be null.”
