How to change @SerializedName, from GSON, of an attribute in a extended class

Question

I have a class like this:

class A {
    @Expose
    @SerializedName("a_id")
    private String id;
}

Now I want to create class B that extends A, but, in B, I want to change the SerializedName of id to "b_id". Is there a way to do this?

It isn't possible out of the box. You'll need to write a custom type adapter. See the Custom Serialization and Deserialization section of the Gson user's guide.
