Class android.location.Location does not define a no-argument constructor xx

Question

I have a trouble in Firebase and package Location

com.google.firebase.database.DatabaseException: Class android.location.Location does not define a no-argument constructor. If you are using ProGuard, make sure these constructors are not stripped.

private void readChanges() {
    reference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            if(dataSnapshot.exists()){
                Location location = dataSnapshot.getValue(Location.class);
            }
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {

        }
    });
}

And i have error : Process: com.example.coffeebakeryfordriver, PID: 15287 com.google.firebase.database.DatabaseException: Class android.location.Location does not define a no-argument constructor. If you are using ProGuard, make sure these constructors are not stripped.

The error message that you get clearly says what the issue is. So please check the duplicate to see how you can solve this, by adding the no-argument constructor to your `Location` class. — Alex Mamo, May 18 '21 at 07:49
`Vitri location = dataSnapshot.getValue(Vitri.class); if (location != null) { myMaker.setPosition(new LatLng(location.getLatitude(), location.getLongitude())); }` — Vĩnh Trường Đặng, May 19 '21 at 08:28
And i fixed this. Because Location no argument on Firebase. Tks for your comment @AlexMamo — Vĩnh Trường Đặng, May 19 '21 at 08:30
