How to fix " java.lang.NoSuchMethodError: com.google.firebase.database.DatabaseReference.setValue"

Question

我正在设置我的当前位置 application.Where 我需要设置编码吗？

    @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)

Answer 1

当您使用 setLocation() 方法而不使用 GeoFire.CompletionListener() 时，此错误似乎会自动出现。如果您实施 CompletionListener，这应该可以解决问题。

因此，替换

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

和

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

编辑 2：
如果您仍然遇到困难，您可能需要适应不同的方法。

替换以下代码：

geoFireAvailable.setLocation(userId, new GeoLocation(location.getLatitude(), location.getLongitude()), new GeoFire.CompletionListener() {
    @Override
    public void onComplete(String key, DatabaseError error) {

    }
});

使用以下代码：

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());

Answer 2

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侦听器：

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

                        }
                    });
