How to get location when it changes

I would like to know there is a way to get location if only it changes? I know android provides this http://developer.android.com/training/location/receive-location-updates.html

Answer 1

 protected void updateNotification() {
         LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
         LocationListener locationListener = new MyLocationlistener();

         lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, normallocationwait, 0.250f, locationListener);
         location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
   }

   private class MyLocationlistener implements LocationListener {

     public void onLocationChanged(Location location){
         if(location!=null){
             if(location.hasAccuracy()){
                   dumpLocation(location);
             }else{
                   dumpLocation(location);
            }
         } 
     }

     public void onProviderDisabled(String provider){
         Log.v("Loc Update","\nProvider disabled: " + provider);
     }

     public void onProviderEnabled(String provider){
         Log.v("Loc Update","\nProvider enabled: " + provider);
     }

     public void onStatusChanged(String provider, int status, Bundle extras){
         Log.v("Loc Update","\nProvider status changed: " + provider + ", status="
                    + status + ", extras=" + extras);
     }
