Question

I’m trying to use simplexml to deserialize an object and code that works using java doesn’t work over Android.

The simple class:

@Root    
public class GenericContainer
{
  @Element
  public MainEntity el;
}

That is declared:

GenericContainer genContainer = new GenericContainer();
genContainer.el = new SubClassBEntity(); //SubClassBEntity is a Subclass of MainEntity

Is serialized and generates a xml:

<?xml version='1.0' encoding='utf-8'?>
<genericContainer>
  <el class="test.entities.SubClassBEntity>
    <x>1</x>
  </el>
</genericContainer>

If I try to deserialize the xml using java all goes ok but if I do the same using android I get a crash where exception message is test.entities.SubClassBEntity.

Any idea to fix this problem?
Thanks

The only solution that I found is use @ElementUnion put all the possibilities inside. It’s a dirty solution because you can have a base class with 50 subclasses and you will have to put all. Automatic refactoring will don’t change the annotations and it will be a piece of error prone code.
