JPA and Android

Question

I plan to use the Google App Engine to communicate with the Android application. I plan on using Objectify, which uses JPA annotations and serializes them using the built-in XML libraries. If I wanted to use the same object at both ends, what should I do with annotations (e.g. @Id, etc.)?

Thanks, John

Answer 1

Starting with version 4, Objectify no longer uses JPA / JDO annotations.

The bad thing is that jar-only annotation is not provided in the standard Objectify distribution. You will need to check its sources and create a “client-bank”, which will be placed in your Android application.
