Android Plateform Anatomy

" summary

Walks through the Android stack from kernel (2.6.25 → 3.x), AOSP vs Linaro vs CyanogenMod forks, and the vendor HAL blob problem that forces manufacturers to ship closed .so files. Explains low-level pieces: binder IPC and ashmem for zero-copy, wake locks vs Linux PM, zygote process, SurfaceFlinger, Stagefright and audio path. Notes compatibility gating by CDD/CTS — roughly 10,000 CTS tests — and why drivers, bootloader and framework patches are the real work to get a device to ship.
