This 5-day course, based on Jonathan Levin's Android Internals books, delves into the architecture and implementation of Android. Participants will explore Android’s features, its relationship to Linux, and how it diverges with its own unique 'Android-isms.' The course covers Android subsystems like the Dalvik Virtual Machine, Android Runtime (ART), Binder IPC, Hardware Abstraction Layer (HAL), and more. It combines theory with hands-on exercises to provide a deep understanding of Android’s architecture from both the user-mode and kernel-mode levels.

Prerequisites

Strong knowledge of Android development or implementation.
Experience in reverse engineering or security research.
A rooted Android device (recommended Android 10 or higher) and a Linux host (VMs can be provided).
Familiarity with Linux and Android systems.

Target Audience

Experienced Android developers or implementers.
Security researchers interested in the internals of the Android OS.

This course is not suitable for user-mode developers focused on Android GUI applications, but it serves as an excellent follow-up for those already familiar with the Android SDK.

We can organize this training at your preferred date and location.

What You Will Learn

Describe the architecture of the Android operating system.
Understand the similarities and differences between Linux and Android.
Trace the core architectural changes from Android Froyo (2.2) to Android 13.0.
Understand the functions and architecture of the Android kernel.
Reverse engineer Android applications.
Monitor, trace, and intercept inter-process communication (IPC) in Android.
Gain a deep understanding of DEX, ART, and OAT formats.
Learn to use free tools such as Dextra, bindump, and jtrace.
Analyse Android security, its evolution, and weaknesses.
