Introduction

Huawei In-App Purchases provides 3 types of product: consumable, non-consumable and auto-renewable subscription.

• Consumable : Consumables are product that can be consumed once. When consumed, it's depleted and can be purchased again.

• Non-consumable : Non-consumables can be only purchased once and do not expire.

• Auto-renewable subscription : Once purchased, Users can access to value-added functions or content in a specified period of time. The subscriptions will automatically renew on a recurring basis until users decide to cancel.

This demo app provides all 3 types of product to demonstrate the procedure and capability of Huawei IAP.

Purchasing consumable product

The demo provides gem as an example of consumable product.

3. Once payment finishes, the consumable demo will increase user's gems counter and call consumeOwnedPurchase API to notify Huawei IAP Service that user has consumed the purchase.

   

   Note: If an exception (such as network error or process termination) occurs after a successful payment, the demo app will attempt to update the gem count when you re-enter the page. (Using obtainOwnedPurchases API to obtain consumable purchases and consumeOwnedPurchase to retry consuming purchases)

   Note: In production you should validate the result on server side (deliver the purchase) before calling consumeOwnedPurchase.
