Developed and delivered a cross-version Music Widget for the Metrolist repository, focusing on playback synchronization and enhanced visibility across multiple Android versions. The work involved addressing resource and compatibility issues by restoring missing string resources, standardizing color definitions in XML, and cleaning up update logic within the MusicService. Leveraging skills in Android development, Kotlin, and UI design, the developer updated documentation and contributor credits to improve project maintainability and discoverability. These efforts strengthened the foundation for future Android version support, improved widget reliability for end users, and streamlined the codebase to reduce upgrade risks and support broader device compatibility.
