How to detect refund with google billingclient library

Question

I was wondering how to detect a refund, or any type of cancelation of an in-app purchase(not a subscription and not a consumable).

I'm currently making my test and when I refund a test in google like that :

The purchase is still present in billingClient.queryPurchaseHistoryAsync() (even in queryPurchase()).

How can I detect such changes and how can I disable my app for refunded users?

Thanks in advance.

Answer 1

Have to tried this function

PurchasesUpdatedListener

Listener interface for purchase updates which happen when, for example, the user buys something within the app or by initiating a purchase from Google Play Store.

void onPurchasesUpdated (int responseCode, 
                List<Purchase> purchases)

Implement this method to get notifications for purchases updates. Both purchases initiated by your app and the ones initiated by Play Store will be reported here.

OnPurchasesUpdated on developer.android
