You must provide an implementation of the IStoreListener
interface which Unity IAPAbbreviation of Unity In App Purchase
See in Glossary uses to inform your application of purchase-related events.
Call the UnityPurchasing.Initialize
method to start the initialization process, supplying your listener implementation and configuration.
Note that initialization will not fail if the network is unavailable; Unity IAP will continue attempting to initialize in the background. Initialization will only fail if Unity IAP encounters an unrecoverable problem such as a misconfiguration or IAP being disabled in device settings.
Consequently Unity IAP may take an arbitrary period of time to initialize; indefinitely if the user is in airplane mode. You should design your store accordingly by preventing users from attempting to make purchases if initialization has not completed successfully.
