Coroutine-Driven Android Billing- Use Cases, Fallbacks, and Functional Programming
summary
Coroutine-based wrappers convert the listener APIs into suspending calls so the billing client is withGoogleBillingClient wrapper that guarantees a connected client behind a mutex and simple retry logic; purchases become suspending via a completableDeferred awaitPurchaseResult that the purchases-updated listener completes. A small functional try sealed class mapping standardizes success/failure; product pricing falls back from ProductDetails to SKU details, products are cached in Room, and unacknowledged purchases get background reconciliation before the 3-day revoke window.
