if someone ever looking for the solution for this issue so here it is:
Collection<String> scopes = new ArrayList<>();
scopes.add(Scopes.PROFILE);
credential = GoogleAccountCredential.usingOAuth2( this, scopes);
credential.setSelectedAccountName(mFirebaseAuth.getCurrentUser().
getEmail());
userProfile = null;
PeopleService service = new PeopleService.Builder(http_transport, JSON_FACTORY, credential)
.setApplicationName(mainActivity.getResources().getString(R.string.app_name)).build();
Person userProfile =
service.people().get("people/100889827937171513174").setRequestMaskIncludeField("person.biographies,person.birthdays,person.genders,person.phone_numbers").execute();
