推荐答案

您是否在继承NativeActivity?

验证和默认的CacheMetadta行为认为您正在添加您的父母作为儿童活动出于某种原因.您可以通过重写CacheMetadata并为它提供一个空的实现来解决此问题，然后对其进行调整，直到您正确声明了Children/Variables元数据为止.

什么时候出现顺便说一下，使用对父母的引用吗?是运行时吗?

Are you subclassing NativeActivity?

Validation and the default CacheMetadta behavior thinks you are adding your parent as a child activity for some reason. You could probably work around happening by overriding CacheMetadata, and giving it an empty implementation to start off with, then tweaking it until you have your Children/Variables metadata all declared correctly.

At what time will you be using the reference to your parent, by the way? Is it runtime?
