Answer 1

you have to create a data reference first

 DatabaseReference ref = FirebaseDatabase.getInstance().getReference("/path/");

than geofire object

        GeoFire geoFire = new GeoFire(ref);

now retreive geo firelocation within particular range like this

 GeoQuery geoQuery = geoFire.queryAtLocation(new GeoLocation(lat, long), radius);
    geoQuery.addGeoQueryEventListener(new GeoQueryEventListener() {
        @Override
        public void onKeyEntered(String key, GeoLocation location) {
            Log.d(Const.TAG,String.format("Key %s entered the search area at [%f,%f]", key, location.latitude, location.longitude));
        }

        @Override
        public void onKeyExited(String key) {
            Log.d(Const.TAG,String.format("Key %s is no longer in the search area", key));
        }

        @Override
        public void onKeyMoved(String key, GeoLocation location) {
            Log.d(Const.TAG,String.format("Key %s moved within the search area to [%f,%f]", key, location.latitude, location.longitude));
        }

        @Override
        public void onGeoQueryReady() {
            Log.d(Const.TAG,"All initial data has been loaded and events have been fired!");
        }

        @Override
        public void onGeoQueryError(DatabaseError error) {
            Log.d(Const.TAG,"There was an error with this query: " + error);
        }
    });
