AOSP Part XII — AI & Devices

Newer cross-device and assistant-oriented surfaces: on-device ML wiring and the companion-device / virtual-device frameworks.

Chapters in this Part

• 51-ai-appfunctions.md — on-device ML in AOSP, NNAPI, AppFunctions framework for assistant integration, Computer Control
• 52-companion-virtual-device.md — CompanionDeviceManager, virtual displays/inputs/cameras, cross-device experiences
• 53-npu-manager.md — the NpuManager mainline module for on-device neural accelerators: model-load admission control (budget/turn-taking policies, priorities), the Rust NDK ANpuBuffer/INpuAllocator, the android.hardware.npu HAL, and libwrapfd buffer protection
