Android 根据链接接收对象是不可能的

按照我创建对象的文档中的规定，我填充对象的属性并将链接保存在数据存储中：

public class InvitationEntity extends GenericJson {
    @Key
    public String objectId;
    @Key
    public int status;
    @Key("_id")
    public String id;
    @Key
    public String name;
}
public class EventEntity extends GenericJson {
    @Key
    public String name;
    @Key
    public String eventDate;
    @Key
    public String location;
    @Key
    public String tip;
    @Key
    public KinveyReference invitations;

    public void initReference(InvitationEntity myInvitation){
        KinveyReference reference = new KinveyReference("invitationCollection", myInvitation.get("_id").toString());
        this.invitations = reference;
    }
}

...

 InvitationEntity invitationEntity = new InvitationEntity();
 invitationEntity.name = "3";
 invitationEntity.objectId="3";
mKinveyClient.appData("invitationCollection", InvitationEntity.class).save(invitationEntity, new KinveyClientCallback<InvitationEntity>() {
                @Override
                public void onSuccess(InvitationEntity invitationEntity1) {
                    Log.e("my", "Ok1 " + invitationEntity1.toString());

                    EventEntity eventEntity = new EventEntity();
                    eventEntity.tip = "33";
                    eventEntity.initReference(invitationEntity1);
                    mKinveyClient.appData("eventCollection", EventEntity.class).save(eventEntity, new KinveyClientCallback<EventEntity>() {
                        @Override
                        public void onSuccess(EventEntity eventEntity_rez) {
                            Log.e("my", "Ok2 " + eventEntity_rez.toString());
                        }

                        @Override
                        public void onFailure(Throwable t) {
                            Log.e("my", "Failed to save entity " + t.getMessage());
                        }
                    });
                }

                @Override
                public void onFailure(Throwable t) {
                    Log.e("my", "Failed to save entity " + t.getMessage());
                }
            });

希望收到：

如何接收对象，使其中没有链接，而是有其他对象？

我是Kinvey的工程师，可以帮助您解决这个问题--我在我们的网站上发布了相同的答案，但我想其他人可能会在这里发现它：

这不是不可能的

在Appdata上，Get和GetEntity方法有多种变体。在这里查看javadocs：

要解析KinveyReferences，请将包含要解析的字段名称的字符串[]作为第二个参数传递给get方法，如果您想使用：

mKinveyClient.appData("eventCollection", EventEntity .class).get(q, new String[]{"invitations"}, new KinveyListCallback() { ... }

现在，onSuccess回调将返回一个EventEntity，但引用已解析，您可以调用：

InvitationEntity myInvite = results[0].getInvitations.getTypedObject(InvitationEntity.class);

请帮助如何使链接被替换为真实对象？

mKinveyClient.appData("eventCollection", EventEntity .class).get(q, new String[]{"invitations"}, new KinveyListCallback() { ... }

InvitationEntity myInvite = results[0].getInvitations.getTypedObject(InvitationEntity.class);
