I have this code running well on a samsung z3:

navigator.geolocation.getCurrentPosition(function(position) {
    		var lat, lon;
			lat = position.coords.latitude;
			lon = position.coords.longitude;
			updateCoordinateDisplay(lat, lon);
			map.setCenter(new google.maps.LatLng(lat, lon));
		}, function() {
			alert("Sorry, we're unable to detect your location");
		});

but as soon as the screen is locked the process stopped

how can activate gps even when mobile is locked ?

Thanks

Hi,

As I know, W3C gelocation apis can only get gps data when AP is awake. so you need to use another api for CPU not to go to sleep state.

But If you use the power api to block sleep, This implementation causes more battery consumption.

Hello,

As Kangsoo Lee comment you can use Power API.

Or you can try to add background-support setting to your config.xml.
