Getting 0.0 for latitude and longitude while showing current location in map

Question

I am using the following code to get my current location. But the problem I am facing is, it always returns 0.0 for latitude and longitude. I have turned on the GPS settings in the phone and set all the permissions. But still I am facing this.

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

customLocationListener = new CustomLocationListener();

locationManager.requestLocationUpdates(

        LocationManager.GPS_PROVIDER,

        0,

        0,

        customLocationListener);

class CustomLocationListener implements LocationListener{ ............

      public void onLocationChanged(Location argLocation) { 

         if(location != null) {     

        int latitude=(int)(argLocation.getLatitude()*1E6);   

        int longitude=(int)(argLocation.getLongitude()*1E6);


              }
       } ........ }

Do any one of you know why?

Note : My activity extends MapActivity not Location Listener

try this way

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


        Criteria locationCritera = new Criteria();
        String providerName = locationManager.getBestProvider(locationCritera,
                true);
        if(providerName!=null)
            location = locationManager.getLastKnownLocation(providerName);

        locationListener = new MyLocationListener();

        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                0, locationListener);

in mylocationlistener set your location object

private class MyLocationListener implements LocationListener {

    public void onLocationChanged(Location loc) {

        if (loc != null) {
            location = loc; 

        }
    }

    public void onProviderDisabled(String provider) {

    }

    public void onProviderEnabled(String provider) {
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
    }
}
