How to convert GeoPoint in Firestore to LatLng

Question

Hi I'm using Android Studio and I'm having trouble of converting data that I've got from Firestore. I saved data in my Firestore type GeoPoint and I want to query it and convert to Object type LatLng.

Here is my code:

    final FirebaseFirestore db = FirebaseFirestore.getInstance();
    final CollectionReference stores = db.collection("stores");
    stores.get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
                @Override
                public void onComplete(@NonNull Task<QuerySnapshot> task) {
                    if (task.isSuccessful()) {
                        for (QueryDocumentSnapshot document : task.getResult()) {
                            Log.i(TAG,document.getData().get("position").toString());
                        }
                    } else {
                        Log.w(TAG, "Error getting documents.", task.getException());
                    }
                }
            });

and Here is what i got

    12-16 10:59:21.557 28239-28239/com.company.yummy.yummy I/firebaseCatch: GeoPoint { latitude=29.339555, longitude=169.715858 }
    12-16 10:59:21.557 28239-28239/com.company.yummy.yummy I/firebaseCatch: GeoPoint { latitude=68.085393, longitude=-42.081575 }
    12-16 10:59:21.557 28239-28239/com.company.yummy.yummy I/firebaseCatch: GeoPoint { latitude=16.503923, longitude=90.196118 }
    12-16 10:59:21.557 28239-28239/com.company.yummy.yummy I/firebaseCatch: GeoPoint { latitude=-69.424524, longitude=-71.356333 }
    12-16 10:59:21.557 28239-28239/com.company.yummy.yummy I/firebaseCatch: GeoPoint { latitude=69.502257, longitude=71.100474 }

All i need is to get latitude,longtitude value to set into LatLng object.

To solve this, you can simply use getGeoPoint() method like this:

GeoPoint geoPoint = document.getGeoPoint("position");

And then use:

double lat = geoPoint.getLatitude();
double lng = geoPoint.getLongitude();
LatLng latLng = new LatLng(lat, lng);
