Problem unmarshalling parcelables

Question

I\'ve got a few classes that implement Parcelable and some of these classes contain each other as properties. I\'m marshalling the classes into a Parcel to pass them between

Answer 1

I had the same problem with the following setup: some handler creates a Message and sends its over a Messenger to a remote service.

the Message contains a Bundle where I put my Parcelable descendant:

final Message msg = Message.obtain(null, 0);
msg.getData().putParcelable("DOWNLOADFILEURLITEM", downloadFileURLItem);

messenger.send(msg);

I had the same exception when the remote service tried to unparcel. In my case, I had overseen that the remote service is indeed a separate os process. Therefore, I had to set the current classloader to be used by the unparcelling process on the service side:

final Bundle bundle = msg.getData();
bundle.setClassLoader(getClassLoader());

DownloadFileURLItem urlItem = (DownloadFileURLItem)
bundle.getParcelable("DOWNLOADFILEURLITEM");

Bundle.setClassLoader sets the classloader which is used to load the appropriate Parcelable classes. In a remote service, you need to reset it to the current class loader.
