GrabLocationDetails.java

Use this code as your GrabLocationDetails.java

 public class GrabLocationDetails extends Service implements LocationListener {

        double lat,lng;
        private LocationManager locationManager;
        private String provider;
        boolean isGps;
        private ArrayList mList;
        Context GLDContext;

        public GrabLocationDetails(Context cont){
            this.GLDContext=cont;
        }
        public GrabLocationDetails(){}
        @Override
        public void onCreate() {
            super.onCreate();
            mList = new ArrayList();
            isGps = false;
            lat=0.0;
            lng=0.0;
        }

        @Override
        public int onStartCommand(Intent intent, int flags, int startId) {

            //super.onStart(intent, startId);

            try {
                locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
                Criteria criteria = new Criteria();
                provider = locationManager.getBestProvider(criteria, false);
                LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
                boolean enabled = service.isProviderEnabled(LocationManager.GPS_PROVIDER);
                if (!enabled) {
                    isGps = false;
                    ListAddItem(isGps);
                    SendBroadcast();
                } else {
                    isGps = true;
                    Location location = locationManager.getLastKnownLocation(provider);
                    lat=(location.getLatitude());
                    lng=(location.getLongitude());
                    ListAddItem(true);
                    SendBroadcast();
                    locationManager.requestLocationUpdates(provider, 400, 1, this);
                }

            } catch (Exception e) {
                ListAddItem(isGps);
                SendBroadcast();
            }
            return super.onStartCommand(intent, flags, startId);
        }

        @Override
        public void onDestroy() {
            super.onDestroy();
            //locationManager.removeUpdates(this);
        }

        public  void SendBroadcast(){
            Intent broadcastIntent = new Intent();
            broadcastIntent.setAction(CommandExecutionModule.LocationDetails);
            broadcastIntent.putExtra("Data", mList);
            sendBroadcast(broadcastIntent);

        }
        public void ListAddItem(boolean GPS) {
            //if(!GPS)
            //mList.add("0");
            //else
            //mList.add("1");
            mList.add(Double.toString(lat));
            mList.add(Double.toString(lng));
        }
