Worked on the cinit/QAuxiliary repository to deliver two targeted features aimed at improving reliability and compatibility for QQ users. Developed a Java hook class to disable the QQ bus card functionality, reducing NFC interference during background operations for QQ version 8.4.10 and above. Extended the SimplifyQQSettingMe feature to support QQ version 8.2.11, adding a configuration entry to ensure correct operation. Focused on Android development using Java and Kotlin, with an emphasis on hooking and reverse engineering via the Xposed Framework. Prioritized maintainability and cross-version compatibility, ensuring clear commit history and minimizing version-specific issues for broader user coverage.
