Can you briefly explain the Android architecture?

Question

Accepted Answer

Android architecture consists of four main layers: Linux Kernel, Hardware Abstraction Layer, Android Runtime, and Application Framework.

Linux Kernel: The foundation of Android, providing core system services like security, memory management, and process management.
Hardware Abstraction Layer (HAL): Interfaces between the hardware and the Android framework, allowing for hardware-specific implementations.
Android Runtime (ART): Executes Android applications and provides core libraries, enabling features like garbage collection and debugging.
Application Framework: Provides higher-level services to applications, including Activity Manager, Content Providers, and Resource Manager.
