DEPRECATED
The BillingClient SDK is deprecated. The BillingClient SDK will continue to function, but resolving issues affecting payment processing may take longer. No new features will be added.
We recommend using the Pay SDK in your projects. To migrate to the Pay SDK, please follow the migration guide.
Implementation examples for Kotlin/Java
Please, look at the application example to learn how to integrate payments in your app.
