Worked on stabilizing batched animation behavior in the facebook/react-native repository, focusing on the NativeAnimated module for Android. Addressed a bug by reverting a previous Kotlin batching change, restoring robust frame and batch number management when JavaScript does not control batching. This technical approach eliminated visual glitches and partial operation issues, resulting in smoother and more consistent animations across devices. Utilized Java and Kotlin to refine the batching lifecycle, cleaned up related code for maintainability, and validated improvements through targeted tests and cross-device checks. The work enhanced animation stability and performance, contributing to a more reliable user experience in React Native.
