fusedLocationProviderClient.lastLocation.addOnSuccessListener always null

Question

I just updated my Location API to use FusedLocationProviderClient but I am having this issue, when I turn off and on the GPS, I am always getting null location:

You can use getLocationAvailability() method on your FusedLocationPrivedClient object and if it returns true then only use getLastLocation() method otherwise use requestLocationUpdates() method like this :

FusedLocationProviderClient fusedLocationProviderClient =
            LocationServices.getFusedLocationProviderClient(InitActivity.this);
    if (ActivityCompat.checkSelfPermission(this.getApplicationContext(),
            android.Manifest.permission.ACCESS_FINE_LOCATION)
            == PackageManager.PERMISSION_GRANTED) {

fusedLocationProviderClient.getLocationAvailability().addOnSuccessListener(new OnSuccessListener() {
                @Override
                public void onSuccess(LocationAvailability locationAvailability) {
                    Log.d(TAG, "onSuccess: locationAvailability.isLocationAvailable " + locationAvailability.isLocationAvailable());
                    if (locationAvailability.isLocationAvailable()) {
                        if (ActivityCompat.checkSelfPermission(InitActivity.this.getApplicationContext(),
                                android.Manifest.permission.ACCESS_FINE_LOCATION)
                                == PackageManager.PERMISSION_GRANTED) {
                            Task locationTask = fusedLocationProviderClient.getLastLocation();
                            locationTask.addOnCompleteListener(new OnCompleteListener() {
                                @Override
                                public void onComplete(@NonNull Task task) {
                                    Location location = task.getResult();                                    
                                }
                            });
                        } else {
                            requestLocationPermissions ();
                        }

                    } else {
fusedLocationProviderClient.requestLocationUpdates(locationRequest, pendingIntent);

                    }

                }
            });
        } else {
            requestLocationPermissions ();
        }
