InAppBilling V3 - "buyData" and "dataSignature" are null when purchasing a subscription item

Question

I have a problem buying subsection items with the new InAppBilling V3

Here is my IABHelper handleActivityResult method:

public boolean handleActivityResult(int requestCode, int resultCode, Intent data) { IabResult result; if (requestCode != mRequestCode) return false; checkSetupDone("handleActivityResult"); // end of async purchase operation flagEndAsync(); if (data == null) { Log.e(TAG + "Null data in IAB activity result."); result = new IabResult(IABHELPER_BAD_RESPONSE, "Null data in IAB result"); if (mPurchaseListener != null) mPurchaseListener.onIabPurchaseFinished(result, null); return true; } int responseCode = getResponseCodeFromIntent(data); String purchaseData = data.getStringExtra(RESPONSE_INAPP_PURCHASE_DATA); String dataSignature = data.getStringExtra(RESPONSE_INAPP_SIGNATURE);\ ... 

purchaseData and dataSignature are null after this code, and as a result, the purchase stream cannot be completed.

When I try to purchase products in the app, everything works well. buyData and dataSignature are not null.

This guy seemed to have the same problem:
Google Play In-App Purchase returns error code -1008: null puchaseData or dataSignature

but this does not work for me, I still get null for both fields.

What am I doing wrong? thanks in advance!

I solved this problem only for testing in REAL. I published the application and signed it with one test account and received valid answers.
