About sdkbox gpg v.2.4.0.1

Hi, i have a question about current gpg js version.
It looks different than old gpg version.

i tried https://github.com/sdkbox/sdkbox-sample-gpg
, read http://docs.sdkbox.com/en/plugins/googleplay/v3-js/
, [sdkbox] GPG - How do I get the gameservice () object
, [SOLVED] SdkBox - Install GPG on Cocos Creator

it seems unable to use gpg.platformconfiguration,
the only function i know how it works is _gpg.GPGWrapper.IsAuthorized();

am i missing something? so that can use gpg.GameServices.Builder() ?

do you mean, you want to use java code ?

erm, nope.
i mean how can i able to use gpg <-- ??
I installed apk in android phone.
In adb shows cannot find gpg.

I just want to sign in google play service to get player info.
By the way, i am using javascript
and using Cocos Creator v1.9.1
