android - Geofire - not found locations

Question

How can I get the all locations that are near to a passed GeoLocation(double lat, double lng) using Geo Queries. I have the following code (and it happens nothing):

public void setCurrentLatLng(double lat, double lng){
    this.lat = lat;
    this.lng = lng;
    GeoLocation geoLocation = new GeoLocation(lat, lng);
    updateCurrenLocation(geoLocation);
    GeoQuery geoQuery = geoFire.queryAtLocation(geoLocation, 8f);
    geoQuery.addGeoQueryDataEventListener(new GeoQueryDataEventListener() {

        @Override
        public void onDataEntered(DataSnapshot dataSnapshot, GeoLocation location) {
            Log.d("geoQuery","onDataEntered "+dataSnapshot.toString());
            // ...
        }

        @Override
        public void onDataExited(DataSnapshot dataSnapshot) {
            Log.d("geoQuery","onDataExited "+dataSnapshot.toString());
            // ...
        }

        @Override
        public void onDataMoved(DataSnapshot dataSnapshot, GeoLocation location) {
            Log.d("geoQuery","onDataMoved "+dataSnapshot.toString());
            // ...
        }

        @Override
        public void onDataChanged(DataSnapshot dataSnapshot, GeoLocation location) {
            Log.d("geoQuery","onDataChanged "+dataSnapshot.toString());
            // ...
        }

        @Override
        public void onGeoQueryReady() {
            // ...
            Log.d("geoQuery","onGeoQueryReady");
        }

        @Override
        public void onGeoQueryError(DatabaseError error) {
            Log.d("geoQuery","onGeoQueryError");
            // ...
        }

    });
    this.setChanged();
    notifyObservers();
    this.clearChanged();
    Log.d("update","clearChanged");
}

And this is my firebase data:

I think I'm open to modify the data struct if needed.
