当我尝试保存通知对象时遇到问题。我尝试过序列化(但通知不可序列化)使用包裹没有运气,然后我找到了一个有前途的方法:GSON

但是在实施并包括图书馆在内的几个问题之后,我再次陷入困境。

这段代码似乎工作正常:

Gson gson = new Gson();
String json = gson.toJson(notification);

但是当我尝试重新构建通知对象时,它会崩溃:

Notification notification = gson.fromJson(json, Notification.class);

这是崩溃日志:

我错过了什么吗?或者只是我无法将 android 类转换为 JSON?如果问题是这样,我是否有另一种方法来存储对象,而不是手动存储通知对象中包含的每个可能的参数?

谢谢!
