由于Unmarshalling异常,我正在恢复应用程序崩溃.我检查了所有Seri​​alizables都没有参数的构造函数,甚至使用ObjectStream检查了所有可序列化(保存到文件并从文件加载).我如何理解导致异常的parcelable偏移的实际类类型:

我们在Play商店记录的崩溃报告中收到此错误.不能在我们所有的测试中复制这个.有没有其他人有同样的问题或解决方案？事实上,我们甚至不知道如何复制这个bug.

所有Parcelable对象都定义了CREATOR,writeToParcel()和contructor.所有列表和复杂类型都被初始化并进行空值检查.

我似乎在我的应用程序中遇到一个奇怪的错误(请参阅GitHub),当我将对象传递给实现的不同活动时会发生这种错误Parcelable.

我已经在Stack Overflow上检查了其他问题和答案,但我无法找到解决方案.我在这里尝试了答案,例如 - 这里仅供参考:

-keepclassmembers class * implements android.os.Parcelable {
    static ** CREATOR;
}

我还确保方法调用writeToParcel是有序的.关于此问题的Stack Overflow上的大多数其他问题都没有答案.

此外,我问一个新问题的原因是因为我认为我的问题是由于我在我的应用程序中使用接口的原因引起的(稍后我将对此进行扩展).Stack Overflow上的其他问题不适合我的特定情况.

在下面,我通过GitHub提供了代码的链接,以便您可以根据需要探索更多代码.

当我单击按钮以启动新活动(传递实现的对象Parcelable)时,会发生崩溃:
