Answer 1

If you want to save an ArrayList of objects to ORMLite the easiest way is this:

@DatabaseField(dataType = DataType.SERIALIZABLE)
private SerializedList<MyObject> myObjects;

and to get my list of objects:

public List<MyObject> getMyObjects() {
  return myObjects;
}

and here is SerializedList:

public class SerializedList<E> extends ArrayList<E> implements Serializable {
}

I think you need to use Foreign Collections. Take a look here:
