IT Certification Overview
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.
