LSFG-Android Frame Generation Skill

Skill by ara.so — Daily 2026 Skills collection.

LSFG-Android ports the lsfg-vk Vulkan frame-generation pipeline to Android. Because Android 12+ blocks external code injection into non-debuggable processes, the app captures the screen via MediaProjection, runs LSFG interpolation on-GPU using AHardwareBuffer sharing, and composites generated frames into a SYSTEM_ALERT_WINDOW or TYPE_ACCESSIBILITY_OVERLAY sitting above the target game.

Repository Layout

LSFG-Android/          # Android Studio project (Kotlin + Compose + JNI/C++)
lsfg-vk-android/       # Submodule: lsfg-vk 1.0.0 + Android patches (#ifdef __ANDROID__)

Both folders must be siblings on disk — the CMake path ../../../../../lsfg-vk-android from inside the JNI sources is hard-coded.
