整理通知包裹 [英] Marshalling a Notification Parcel

问题描述

我正在尝试将Notification对象写入文件. 我能找到的最好方法是将对象写入一个包裹，将其封送以获取字节[]，然后将其写入文件.

I'm trying to write a Notification object to a File. The best way I could find was to write the object to a parcel, marshall that parcel to get a byte[] and then write it to a file.

Parcel notif = Parcel.obtain();
notification.writeToParcel(notif, 0);
byte[] notifArray = notif.marshall();

我尝试封送包裹时遇到运行时异常: 试图封送一个包含活页夹对象的包裹."

I get a Runtime exception when I try to marshall the parcel though: "Tried to marshall a Parcel that contained Binder objects."

是否有更好的方法将Notification对象写入文件?否则，我该如何使用这种方法?

Is there a better way of writing Notification objects to file? Else, how do I get this approach to work?

推荐答案

该通知包含一个活动/活动活页夹对象.它不是为了用于保存状态(以byte []形式)而是为了IPC的目的而实现了Parcelable.理想情况下，您应该保存必要的字段，而不是对象本身.

The notification contains a live/active binder object. It wasn't built to be used for saving the state (in a byte[]) rather it implements Parcelable for IPC purposes. You should ideally save the necessary fields rather than the object itself.
