Finding the current location for Windows 8 App

Question

I need to find the current location on windows 8 App but its always results in error.

Here is the code i am using :

try {           
    var loc = Windows.Devices.Geolocation.Geolocator();
    loc.getGeopositionAsync().then(getPositionHandler, errorHandler);
    } catch (e) {
    // Catch Errors
}

This always results in errorHandler with the error "cancelled".

Also i am trying this on a laptop. Any idea why this is not working ?

Thanks.

Answer 1

did you changed the manifest and add the capability? can you send a repro project that we can try out?

Answer 2

This happens because the loc variable goes out of scope before the async operation is completed, resulting in a cancelation. This behavior is particular to the geolocator, and is something I've confirmed with the engineering team. I wrote about this on my blog as well: http://kraigbrockschmidt.com/blog/?p=1120.

Put the var loc = line outside the function so it stays in scope, and it should work for you.
