Android, Serializable/Parcelable problem in client-server app

I want to send complex data from my android to a remote server via TCP-sockets. I know that I need to serialize the Objects. In Android this is done via parcelable. But this is an android specific interface and the server only knows the serializable interface. Also vice-versa android doesn't know a serializable interface.

Both the android and the server must "know" the object but they are implemented in two different ways (server--> serializable, android --> parcelable)

How do I use these interfaces properly, so that I can send Objects via TCP to the server successfully?

According to http://developer.android.com/reference/android/os/Parcel.html it is not appropriate to use a parcel for persistant (or network) serialization:

Parcel is not a general-purpose serialization mechanism. This class (and the corresponding Parcelable API for placing arbitrary objects into a Parcel) is designed as a high-performance IPC transport. As such, it is not appropriate to place any Parcel data in to persistent storage: changes in the underlying implementation of any of the data in the Parcel can render older data unreadable.

Why not use Simple XML serialization, works with both Android and Java 1.5+. Its located at the following site.

http://simple.sourceforge.net

Also, the framework is fairly small and suitable for mobile platform (approx 270K with no dependencies). And it much more performant than most XML serialization or binding frameworks.

We had the same issue here at work and we switched to JSON. Maybe you should consider doing the same?!

Edit: Android does know the Serializable interface. How could I forgot...
