Answer 1

Use the 'named' annotation...

@ApiMethod(name = "sendStuff")
public void sendStuff( @Named("clientId") String clientId, @Named("stuff") String stuff )

And for android, the client code would look like this

SendStuff sl = service.sendStuff( clientId, stuff );

You can't send multiple entity types in the body of your request. You'll need to create a wrapper entity that contains those two entities, e.g.:

class MyWrapperEntity {
  MyEntity someEntity;
  MyOtherEntity someOtherEntity;
  // ...
}

However, that's not what your example shows (the entities are the same type). Use a List<MyEntity> or Map<String, MyEntity> inside of a collection entity instead, e.g.:

class MyEntityCollection {
  List<MyEntity> items;
  // ...
}
