I'm setting up a current location in my application.Where do i need to set the encoding?

    @Override

public void onLocationChanged(Location location) {

    mLastLocation = location;

    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());

    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));

    mMap.animateCamera(CameraUpdateFactory.zoomTo(11));



    //Geo Fire for current location

    String userId = FirebaseAuth.getInstance().getCurrentUser().getUid();

    DatabaseReference refAvailable = FirebaseDatabase.getInstance().getReference("driversAvailable");

    DatabaseReference refWorking = FirebaseDatabase.getInstance().getReference("driversWorking");



    GeoFire geoFireAvailable = new GeoFire(refAvailable);

    GeoFire geoFireWorking = new GeoFire(refWorking);



    switch (customerId){

        case "":



            geoFireWorking.removeLocation(userId);

            geoFireAvailable.setLocation(userId, new GeoLocation(location.getLatitude(), location.getLongitude()), new GeoFire.CompletionListener() {

                @Override

                public void onComplete(String key, DatabaseError error) {



                }

            });



            break;

            default:

                geoFireAvailable.removeLocation(userId);

                geoFireWorking.setLocation(userId, new GeoLocation(location.getLatitude(), location.getLongitude()), new GeoFire.CompletionListener() {

                    @Override

                    public void onComplete(String key, DatabaseError error) {



                    }

                });



                break;

    }





}

Following is error which I'm getting:

java.lang.NoSuchMethodError: com.google.firebase.database.DatabaseReference.setValue
at com.firebase.geofire.GeoFire.removeLocation(GeoFire.java:215)
at com.firebase.geofire.GeoFire.removeLocation(GeoFire.java:192)
at com.example.webforest.quickaidlikeuber2nd.DriverMapActivity.onLocationChanged(DriverMapActivity.java:184)

This bug appears to manifest automatically when you are using setLocation() method without the use of GeoFire.CompletionListener(). If you implement the CompletionListener, this should resolve the issue.


Therefore, replace

geoFire.setLocation(userId, new GeoLocation(location.getLatitude(), location.getLongitude()));

with

geoFire.setLocation(userId, new GeoLocation(location.getLatitude(), location.getLongitude()), new GeoFire.CompletionListener(){ });

Edit 2:
You may need to adapt to a different approach if you are still encountering difficulties.

Replace the following code:

geoFireAvailable.setLocation(userId, new GeoLocation(location.getLatitude(), location.getLongitude()), new GeoFire.CompletionListener() {

    @Override

    public void onComplete(String key, DatabaseError error) {



    }

});

With the following code:

GeoHash geoHash = new GeoHash(new GeoLocation(location.getLatitude(),location.getLongitude()));

Map<String, Object> updates = new HashMap<>();

updates.put("g", geoHash.getGeoHashString());

updates.put("l", Arrays.asList(location.getLatitude(),location.getLongitude()));

geoFireAvailable.setValue(updates,geoHash.getGeoHashString());

Geofire has changed a bit, now to make a removeLocation work you have to add a listener like this:

 //after updating 

                    geoFireWorking.removeLocation("id of the node you want to remove", new GeoFire.CompletionListener() {

                        @Override

                        public void onComplete(String key, DatabaseError error) {



                        }

                    });
