Sending an object as a parcel (with file descriptors) using exception exceptions

Question

Sending an object as a parcel (with file descriptors) using exception exceptions

I am trying to send an array of StatusBarNotifications to another service, so I did this:

Service that extends 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); }

But I get a RuntimeException regarding file descriptors.

I found some links to this problem, for example, here . The answer mentions the following:

use Bundle.putBinder () to pass a Binder that will return Parcel with ParcelFileDescriptor (from API 18). But I do not understand how to implement this.

Another guy in this link here mentions the following:

If I return the PaecelFileDescriptor from the ContentProvider, it works fine.

But I do not understand what he means.

The last link is here . It solves the same problem as me, but there seems to be no solution.

Does anyone understand these potential solutions that I have linked? Is there a workaround for this problem, a potentially different way to send data (StatusBarNotification [] (it extends Parcelable))?

Here is the log:
