The new Klepton project enables Android ARM64 VR applications to run on Apple Vision Pro and macOS by translating native libraries without requiring Just-In-Time compilation.

Key Points

• Klepton uses the klepton-ld tool to convert Android .so libraries into Apple-compatible .dylib and .framework formats.
• Graphics rendering is handled by translating GLES 3.2 to ANGLE GLES 3.0 and Vulkan to MoltenVK for Metal compatibility.
• The runtime provides reimplementations of Android-specific components like ALooper, ANativeWindow, and JNIEnv to bridge the OS gap.
• Developers can currently run the game Beat Saber on visionOS and macOS, though some minor graphical issues remain.
• The project includes automated build scripts for macOS and visionOS, with ongoing work to support Steam VR Link.

Why it Matters

This development significantly lowers the barrier for porting existing Android-based VR content to Apple’s spatial computing platform. By bypassing the need for JIT compilation, Klepton provides a viable path for developers to bring legacy VR titles to the Vision Pro ecosystem.
