This book takes you from understanding Android to engineering it at scale. You’ll learn how real performance problems emerge across the runtime, scheduler, Binder, GPU, memory system, and rendering pipeline, then trace them with the same tools used by platform engineers. Instead of memorizing APIs, this book teaches you to think in end-to-end latency paths, frame budgets, thermal limits, and concurrency graphs. By the end, you’ll be able to diagnose ANRs and jank systematically, modify AOSP for real devices, build custom ROM features, and contribute meaningful patches to projects like AOSP and LineageOS with confidence.
