Worked on maintaining and improving dependency management for the stone-payments/demo-sdk-android repository, focusing on upgrading the Stone SDK version in the Gradle build configuration from 4.11.1 to 4.11.5. This update ensured ongoing compatibility with the latest SDK improvements and reduced technical debt, while intentionally introducing no changes to runtime behavior or user-facing features. The approach prioritized long-term stability and maintainability, preparing the codebase for future enhancements. The work leveraged Gradle and Android development skills, emphasizing careful dependency management to support a robust integration environment and enable smoother adoption of new features in subsequent development cycles.
