In-App Purchases Updates from Google I/O 2021

Google I/O introduced several new in-app subscription tools and features aimed at enhancing user experience and developer capabilities, including multi-quantity purchases, multi-line subscriptions, and prepaid plans. These features allow users more flexibility, such as selecting quantities of consumable products, managing multiple products within a single subscription, and using prepaid plans for fixed access periods. To utilize these updates, developers must implement the Play Billing Client 4.0 in their apps. Additionally, new engagement metrics and benchmarks will offer developers insights into app performance, while the Digital Goods API will enable PWA apps to sell digital items using Google Play Billing. The Google Play SDK Console will give SDK developers access to usage and crash statistics, improving communication and information sharing with app developers.
