Qi Qi developed multi-window replay support for the LunarG/gfxreconstruct project on Android, enabling the application to manage multiple SurfaceViews through a new ReplayActivity. This work required integrating Java and native C++ code using JNI to facilitate seamless window management across language boundaries. Qi Qi aligned the implementation with Android’s lifecycle and UI threading requirements, ensuring stable and reliable operation of multi-window replay scenarios. The feature was delivered using skills in Android development, graphics programming, and CMake, addressing the need for advanced replay capabilities on Android. The work demonstrated depth in cross-language integration and careful handling of platform-specific constraints.
