Boot Process
Learn how Android boots from the bootloader to the system UI, including the role of the kernel, init, and Zygote.
Core System Components
SELinux
Security-Enhanced Linux (SELinux) enforces mandatory access control, improving Android security by confining processes and restricting access.
Verified Boot
Ensures system integrity by verifying the boot chain from bootloader to system partition, preventing unauthorized modifications.
Vendor Partition
Separate partition for vendor-specific code and drivers, enabling modular updates and better maintainability.
System as Root
Modern Android architecture where the system partition is mounted as root, improving security and update mechanisms.
System Updates
OTA Updates
Over-the-Air updates allow seamless system updates without user intervention or data loss.
A/B Partitioning
Dual partition system enabling seamless updates with rollback capability and minimal downtime.
Project Treble
Modular architecture separating vendor implementation from Android framework for easier updates.
Dynamic Partitions
Flexible partitioning system allowing dynamic allocation of storage space for different partitions.
Advanced Topics
Init Process
First user-space process that initializes the system, starts services, and manages system lifecycle.
Zygote Process
Pre-initialized process that forks to create new app processes, improving startup performance.
System Server
Core system service that manages Android framework services and coordinates system operations.
Binder IPC
Inter-Process Communication mechanism used throughout Android for secure service communication.
