Which billing library version we are using for Android?

[tusharprajapati8888]

I'm using the '7.5.0' library version for in-app purchases.

"react-native-iap": "^7.5.0",

This question is regarding the Android app (billing library version) com.android.vending.BILLING

I want to know :

1. Which billing library version we are using for Android?

2. If we are using an older billing library version how to upgrade to the new billing version?

In the webhook call, we are getting this response on our backend side.

I have also followed this documentation for android library installation but seems like it is working without the billing library version mentioned in android native level.

As per google document, they are saying that the app must use Billing Library version 3 or newer : Billing Deprecation

In the android native level, We can set Google Play Billing Library dependency like this.

Could anyone please help me with this?
I really appreciate it, Thanks in advance.
