Android architecture is like a layered cake. Each layer has its own job, and together they make sure Android runs smoothly on millions of devices worldwide. Let’s break down these layers

1. Linux Kernel (The Core Layer)

At the heart of Android is the Linux Kernel. This is the foundation, responsible for managing hardware drivers, memory, process management, and more. Think of it as the bridge between the hardware (like your phone’s CPU, camera, etc.) and the software (the apps).

2. Hardware Abstraction Layer (HAL)

The Hardware Abstraction Layer (HAL) allows Android to communicate with the hardware (e.g., camera, sensors, GPS) without worrying about hardware-specific implementations. The HAL acts like a translator between the device hardware and the higher levels of Android.

3. Android Runtime (ART) & Core Libraries

When an Android app runs, it uses Android Runtime (ART), which is a kind of virtual machine (like a translator) that allows your app’s code to run smoothly on any Android device. Before ART, Android used Dalvik VM(so you might hear both…
