How to get lattitude and Longitude with only GPS

How to get the Location only through GPS without any kind of Internet connection. I use the below code to get the location but not working without the internet. Please let me know why I'm not getting the location without internet

        boolean isGPSEnabled = manager
                .isProviderEnabled(LocationManager.GPS_PROVIDER);
       boolean isNetworkEnabled = manager
                .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
        if (!isGPSEnabled && !isNetworkEnabled) {
            // no network provider is enabled
        } else {
            // First get location from Network Provider
            if (isNetworkEnabled) {

                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                }
                manager.requestLocationUpdates(
                        LocationManager.NETWORK_PROVIDER,
                        MIN_TIME_BW_UPDATES,
                        MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                Log.d("Network", "Network");
                if (manager != null) {
                    location = manager
                            .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                    if (location != null) {
                        currentLatitude = location.getLatitude();
                        currentLongitude = location.getLongitude();
                    }
                }
            }
            // if GPS Enabled get lat/long using GPS Services
            if (isGPSEnabled) {
                if (location == null) {
                    manager.requestLocationUpdates(
                            LocationManager.GPS_PROVIDER,
                            MIN_TIME_BW_UPDATES,
                            MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                    Log.d("GPS Enabled", "GPS Enabled");
                    if (manager != null) {
                        location = manager
                                .getLastKnownLocation(LocationManager.GPS_PROVIDER);
                        if (location != null) {
                            currentLatitude = location.getLatitude();
                            currentLongitude = location.getLongitude();
                        }
                    }
                }
            }
            Log.d(TAG, "getLocation: "+currentLatitude+"   "+currentLongitude);
        }

    } catch (Exception e) {
        e.printStackTrace();
    }

Firstly, the code scope you pasted is famous, it's combination of last known locations of network and GPS providers. Even getLastKnownLocationmethods are called just after requestLocationUpdates methods, this usage is fully not trusted. Because those sensors won't give result in sync way.

You have two options, one is to call getLastKnownLocation to get last obtained location for GPS, and second is to make location request with requestLocationUpdates. Choosing this, will be determined by your scenario.

Use this short code to get lattitude and Longitude with only GPS 

LocationManager manager = (LocationManager) getSystemService(LOCATION_SERVICE);
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
            Location location = manager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
            Log.d("Location = ","Longitude "+location.getLongitude()+",Latitude "+location.getLatitude());
