android - Naming convention with Firebase serialization/deserialization?

Question

I wonder to know how Firebase serialize/deserialize POJO object to/from json, does it use Jackson or Gson or any similar library else.
I have trouble about naming convention with Firebase. My model some like this:

class Data {
    private String someFieldName;
    private String anotherFieldName;
    public Data() {}
    public void setSomeFieldName(String) {...}
    public String getSomeFieldName(String) {...}
    public void setAnotherFieldName(String) {...}
    public String getAnotherFieldName() {...}
}

And the expected result in Firebase should be:

{
    "some_field_name" : "...",
    "another_field_name" : "..."
}

with Gson I can use FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES for my purpose, as in Gson doc:

Here's a few examples of the form "Java Field Name" ---> "JSON Field Name":

• someFieldName ---> some_field_name

• _someFieldName ---> _some_field_name

• aStringField ---> a_string_field

• aURL ---> a_u_r_l

---

How can I convert my POJO object to "Firebase value" with specific naming convention and vice versa, or there are any way to customize the serialize/deserialize process?

Thanks!
