android - 如何修复 "java.lang.NoSuchMethodError: com.google.firebase.database.DatabaseReference.setValue"

Question

我正在我的应用程序中设置当前位置。我需要在哪里设置编码？

    @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;
    }


}

以下是我得到的错误:

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)

Geofire 发生了一些变化，现在要使 removeLocation 起作用，您必须像这样添加一个监听器:

 //after updating 
                    geoFireWorking.removeLocation("id of the node you want to remove", new GeoFire.CompletionListener() {
                        @Override
                        public void onComplete(String key, DatabaseError error) {

                        }
                    });
