Не удается узнать текущую широту и долготу текущего местоположения в HTC исследовать?

Я могу получить текущую широту и долготу текущего местоположения в Galaxy pop, galaxy y. Но я не могу найти текущее местоположение в HTC?

Кодирование, которое я использую, выглядит следующим образом:

    @Override
    protected void onStart() {

            // TODO Auto-generated method stub

            super.onStart();
            context = Context.LOCATION_SERVICE;
            locationManager = (LocationManager)getSystemService(context);
            locationManager.requestLocationUpdates(provider, 1, 1, locationListener);
            crta = new Criteria();
            crta.setAccuracy(Criteria.ACCURACY_FINE);
            crta.setAltitudeRequired(false);
            crta.setBearingRequired(false);
            crta.setCostAllowed(true);
            crta.setPowerRequirement(Criteria.POWER_LOW);
            //String provider = locationManager.getBestProvider(crta, true);
             String provider = LocationManager.GPS_PROVIDER;
             location = locationManager.getLastKnownLocation(provider);
             updateWithNewLocation(location);
            }

            private void updateWithNewLocation(Location location) {
                        String latLong;             
'enter code here'//                      myLocation = (TextView) findViewById(R.id.myLocation);
                        String addressString = "no address found";


                        if(location!=null) {
            System.out.println("Provider " + provider + " has been selected.");
            lat  = (Double) (location.getLatitude());
            lng  = (Double) (location.getLongitude()); 
        // Gomathi
                                    double valueofGPSlat = lat * 1000;

                                    // Get Current Location
                                    latt = Double.toString(GPSvalue);

                                    longt = Double.toString(resultGPSvalue);
            // GomathiEnd
                        } else {
                        latLong = " NO Location Found ";
                        }
                        //myLocation.setText("your Current Position is :\n" +latLong + "\n " + addressString );

                        Toast.makeText(UsertaskoptionsActivity.this,"your Current Position is :\n" +latt + "\n " + ""+longt , Toast.LENGTH_LONG).show();
                        }

            private LocationListener locationListener = new LocationListener()
            {
