README - In-App Purchasing Sample Scenes - Google Play Store - Restoring Transactions

This sample showcases how to use the Google Play Store extensions to restore transactions. This allows users to be granted Non-Consumable and Subscription products they already own after reinstalling the application.

Instructions to test this sample:

1. Have in-app purchasing correctly configured with the Google Play Store.
2. Configure a non-consumable product.
3. Set your own product’s id in the InAppPurchasing game object > Restoring Transaction script > No Ads Product Id field or change the noAdsProductId field in the RestoringTransaction.cs script.
4. Build your project for Android and make sure the GooglePlayStore is selected*.

*You can change the currently selected store under Services > In-App Purchasing > Configure and changing the Current Targeted Store field.

Restoring Transactions

When a user reinstalls your application they should be granted any Non-Consumable or renewable Subscription products they already own. App stores maintain a permanent record of each user’s Non-Consumable and renewable Subscription products which Unity IAP can retrieve.

On the Google Play Store, Unity IAP automatically restores any products the user owns during the first initialization following reinstallation; the ProcessPurchase method of your IStoreListener will be called for each owned item.

See the documentation on the topic for more information.
