任何人都可以提供相同的帮助。相同的代码在Android 9和其他设备上运行
解决方法
您似乎正在尝试序列化destructor TDataModule.Destroy;
begin
if not (csDestroying in ComponentState) then GlobalNameSpace.BeginWrite;
。序列化您无法控制的类是有风险的，但是在这种情况下，它不起作用，因为它有一个名为ColorStateList的字段，而抽象基类mChangingConfigurations也有一个名为{{ 1}}。 GSON无法处理序列化具有相同名称的两个不同字段，因此失败。
在不知道您的特定用例的情况下，我的一般建议是避免序列化您无法控制的类。如果需要能够从序列化数据中重新创建它们，则可以序列化构造它们所需的特定数据（例如，特定的颜色int和状态）。
