How RevenueCat handles errors in Google Play’s Billing Library

The blog post discusses the intricacies of using Google's Play Billing Library for managing in-app purchases and how RevenueCat offers a comprehensive solution to enhance this process. Initially, the post outlines the challenges faced with error handling in the Play Billing Library, particularly the issues with Google's suggested retry mechanisms, which led to infinite reconnection loops and inconsistencies, especially when language changes on a device or on certain Samsung devices. RevenueCat's approach involves implementing a nuanced error handling strategy, categorizing errors into retryable and non-retryable types, and applying mechanisms like simple retries, exponential backoff, and error propagation based on the context. The post emphasizes that Google has since updated its documentation to better guide developers, and RevenueCat's solution now offers advanced features such as detailed analytics and cross-platform support, simplifying developers' tasks and improving user experience.
