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.

Result

Once you start the demo, you should be able to see the following page.

Purchasing consumable product

The demo provides gem as an example of consumable product.

1. Tap Consumable products, you should be able to see the home page for consumable demo. The demo will call the obtainProductInfo API, to query the detail of managed products. (And also retries consumeOwnedPurchase, see below.)

   

2. Tap 5 gems, the demo will call the createPurchaseIntent API, and jump to the checkout page which is provided by IAP Service.

   

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.
