Worked on the libsdl-org/SDL repository to enhance Android input reliability and streamline the codebase. Addressed duplicated joystick axes during polling, improving input accuracy and reducing inconsistent axis events for Android users. Used C and Java to implement these changes within the SDL Android backend, aligning with Android NDK standards. Also removed accelerometer-as-joystick support by eliminating related code and onNativeAccel handling, which simplified maintenance and reduced input noise. These efforts resulted in a safer, more reliable input experience and a leaner codebase, supporting faster iteration and lowering the risk of regressions for Android SDL game development projects.
