how to get latlng from LocationSettingsResponse method?

I am Trying to make a map activity that i can choose my current location and make a marke on any location in the map,, i tried to use google documentation but i didn't understand how can i get latlng from this method any one have and idea about that !

LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setInterval(10000);
    locationRequest.setFastestInterval(5000);
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);
    // ...

    SettingsClient client = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());

    task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            // All location settings are satisfied. The client can initialize
            // location requests here.
            // ...
            

        }
    });

For your problem create a function like follows :

 public void centreMapOnLocation(Location location, String title){
if (location != null) {
LatLng userLocation = new LatLng(location.getLatitude(), location.getLongitude());
mMap.addMarker(new MarkerOptions().position(userLocation).title(title));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(userLocation, 15));
}
}

In onMapReady function add the following code :

 @Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setOnMapLongClickListener(this);
mMap.clear();
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
locationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
centreMapOnLocation(location, "Your Location");
}
@Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
@Override
public void onProviderEnabled(String s) {
}
@Override
public void onProviderDisabled(String s) {
}
};
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0 , 0, locationListener);
Location lastKnownLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
centreMapOnLocation(lastKnownLocation, "Your Location");
}else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION},1);
}
}

In the onMapLongClick :

Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
String address = "";
try {
List<Address> listAddresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
if(listAddresses != null && listAddresses.size() > 0){
if (listAddresses.get(0).getThoroughfare() != null){
address += listAddresses.get(0).getThoroughfare() + " ";
}
address += listAddresses.get(0).getSubThoroughfare() + " ";
}
}catch (Exception e){
e.printStackTrace();
}
if (address.equals("")){
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm dd-MM-yyyy");
address += sdf.format(new Date());
}
mMap.addMarker(new MarkerOptions().position(latLng).title(address));
SharedPreferences sharedPreferences = this.getSharedPreferences("com.luv.memorableplaces", Context.MODE_PRIVATE);
try {
ArrayList<String> lat = new ArrayList<String>();
ArrayList<String> lng = new ArrayList<String>();
for (LatLng coord : MainActivity.locations){
lat.add(Double.toString(coord.latitude));
lng.add(Double.toString(coord.longitude));
sharedPreferences.edit().putString("latitudes", ObjectSerializer.serialize(lat)).apply();
sharedPreferences.edit().putString("longitudes", ObjectSerializer.serialize(lng)).apply();
}
sharedPreferences.edit().putString("places", ObjectSerializer.serialize(MainActivity.places)).apply();
}catch (Exception e){
e.printStackTrace();
}
Toast.makeText(this, "Location Saved", Toast.LENGTH_SHORT).show();

This will also help you save the previous location. Try it out, it should work.
