Hardware Abstraction Layer (HAL)

The hardware abstraction layer connects the kernel with upper system layers and enables vendors to make system changes without modifying fundamental system code.

Android Runtime (ART)

The system operates apps with better efficiency because it replaces the older Dalvik system, which requires less time to start applications & improves battery performance.

Native Libraries

C/C++ applications can access media and graphics engine tools through native libraries.

Application Framework

The system provides developers with APIs that enable access to contacts, notifications and other functions to build their applications.

Apps Layer

Your games, browsers, and tools exist in this space that allows them to reach the underlying system components securely.

What Is AOSP?

The Android Open Source Project (AOSP) provides Google with its open-source source codebase, which manufacturers such as Samsung use to create their own customized Android versions without paying any licensing fees. The system operates stock Android through devices which include Pixel phones while it hire Android app developers to create applications.

Android’s Standout Features: What Makes It Unbeatable

Android system offers its users many strong features that enable them to use the system for various common activities. What is Android’s edge?
