Getting Android location from GCMIntentService

I want to get the location of a user in Android when he receives a GCM notification.
so in my GCMIntentService extends GCMBaseIntentService I'm doing this : 

   @Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message. Extras: " + intent.getExtras());
        String message = getString(R.string.gcm_message);
        displayMessage(context, message);
        syncLocations(context);

    }

In syncLocation I'm doing things correctly to get the location

public void syncLocations(Context context)
    {

        locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);

            locationManager.requestLocationUpdates(
                    LocationManager.GPS_PROVIDER, 0, 0,
                    mLocationListener);
            locationManager.requestLocationUpdates(
                    LocationManager.NETWORK_PROVIDER, 1000, 0,
                    mLocationListener);

    }
    public LocationListener mLocationListener   = new LocationListener() {
        @Override
        public void onStatusChanged(
                String provider,
                int status,
                Bundle extras)
        {}

        @Override
        public void onProviderEnabled(
                String provider)
        {}

        @Override
        public void onProviderDisabled(
                String provider)
        {}

        @Override
        public void onLocationChanged(
                Location location)
        {
//HANDLE LOCATION
        }
    };

syncLocation works correctly if it is called from inside the app.

But when i call it from the notification onMessage(), it enters the method, but onLocationChanged is never called. I suspect it has something to do with the context.

Can anyone please give me any info why it isn't working ?
Thanks

Because GCMIntentService is an IntentService and goes away (via stopSelf()) shortly after onMessage() returns. You cannot reliably do things like register listeners for location changes from an IntentService.

Also, bear in mind that the device may be asleep when the GCM message comes in. GCMIntentService will keep the device awake long enough to call onMessage(), but once onMessage() returns, the device can fall back asleep.
