### Course Outline

Our newly redesigned 5-day (45-hour) Android Internals course offers a complete, layer-by-layer exploration of the Android Operating System — from the silicon up to the APK. It opens with the platform's historical evolution and the relationship between AOSP and Google Mobile Services, then moves into a rigorous study of the architectural layers: the Linux kernel and its Android-specific additions, the HAL, Bionic, the ART runtime, the NDK, and the Java/Kotlin API Framework. Students gain a deep, first-principles understanding of the full boot chain (bootloader → vmlinux → init → Zygote → System Server), the ROM partition structure (boot.img, system.img, vendor.img, vbmeta.img), Verified Boot and dm-verity, memory and process management, and the Android security model — implemented through both Linux-based process isolation (the App Sandbox) and SELinux Mandatory Access Control.Beyond theory, the course is roughly 75% hands-on — 17 practical labs across the five days, covering everything from init.rc tracing and factory-image forensics, through live Binder transaction analysis at the kernel-driver level, to end-to-end AIDL services built between two separate applications. Students write native C++ components using the NDK, bridge them into the framework with JNI, and learn to access driver interfaces directly through /dev and /sys. The course also drills into Reflection and Hidden APIs, Project Treble, the full Binder IPC framework (Proxy, Stub, Parcel, ServiceManager, ioctl and the Transaction Stack), and finishes with a capstone reverse-engineering lab using JEB and Frida on a purpose-built malicious sample — including root-detection bypass and full data-flow tracing. Whether your team is new to Android's internals or needs to extend existing expertise at the kernel, HAL, or security level, this course equips participants with the knowledge and tooling to operate at every layer of the system.
