通过intent将对象作为Parcel(带有文件描述符)发送会导致异常

Question

我正在尝试将一组StatusBarNotifications发送给我的另一个服务,所以我这样做了:

扩展的服务NotificationListenerService:

@Override
public void onNotificationPosted(StatusBarNotification sbn) {
    // TODO Auto-generated method stub
    StatusBarNotification[] activeN = super.getActiveNotifications();               

    Intent i = new Intent(this, CoreTwo.class);
    i.putExtra("activenotifications", activeN);
    startService(i);
}

但我得到一个关于文件描述符的RuntimeException.

我只找到几个环节解决这一问题,例如这一个在这里.答案提到了以下内容:

使用Bundle.putBinder()传递一个Binder,它将使用ParcelFileDescriptor(来自API 18)返回一个Parcel.但我不明白如何实现这一点.

此链接中的另一个人在这里提到以下内容:

如果我从ContentProvider返回PaecelFileDescriptor,它可以正常工作.

但我不明白他的意思.

最后一个环节是这个位置.它解决了与我相同的问题,但似乎没有解决方案.

有人理解我链接的这些潜在解决方案吗？是否有针对此问题的解决方法,可能是另一种发送数据的方式(StatusBarNotification [](它扩展了Parcelable))？

这是日志:

非常感谢这里的一些帮助,因为我无法解决这个问题,而且它已经开始向我倾斜了,谢谢
