The google play developer documentation for in-app-purchase subscriptions states
Before your app enters the billing flow, you can call isFeatureSupported() to determine whether the device supports the products you want to sell
When calling this method, it's javadoc states
returns BILLING_RESULT_OK if feature is supported and corresponding error code otherwise
I cannot locate the BILLING_RESULT_OK constant in any of the billing classes and cant find the reference in the documentation. What is the right value/constant to compare the response code to?
Is BILLING_RESULT_OK the same as BillingClient.BillingResponseCode.OK?
Use BillingClient.BillingResponseCode.OK
The documentation hasn't been updated for some time now. Even the official sample uses BillingClient.BillingResponseCode.OK.
