биллинг андроид-студии не может получить купленный токен

Question

Я работаю с «Billing», вся система работает, но я не могу получить токен покупки и DeveloperPayload, когда завершаю покупку, каждый раз, когда я пытаюсь это сделать, я получаю нулевые значения ThePurchaseToken и DeveloperPayLoad

Я пытался с

Purchase purchase;
ConsumeParams consumeparams;

purchase.getPurchaseToken();
purchase.getDeveloperPayload();
consumeparams.getPurchaseToken();
consumeparams.getDeveloperPayload();

все на OnPurchasesUpdated

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_poner_dinero);

    LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
                new IntentFilter("custom-message"));

}

Мне нужно получить DeveloperPayload и getPurchaseToken от покупки, чтобы иметь возможность потреблять продукт

Я руководствовался документацией:

https://developer.android.com/google/play/billing/billing_onetime

Есть идеи?спасибо
