This third book is where Android stops feeling like a framework and starts revealing itself as a complete systems platform. You’ll trace how a touch travels from a hardware interrupt to a View, how frames move through SurfaceFlinger and the GPU pipeline, how JNI bridges Java and native code, and how services inside system_server coordinate the entire device. The book builds a deep mental model of Android across every layer, from Linux kernel drivers and HALs to Binder IPC, graphics, input dispatch, and runtime internals. Through a full end-to-end location stack case study, you’ll learn how hardware sensors, native services, fusion algorithms, and app APIs work together in real devices, giving you the skills to debug performance issues, battery drain, ANRs, and system instability at the level real Android platform engineers operate.
