The software architecture of Android is based on a layered approach, with each layer providing specific functionalities and services. Here are the key layers of the Android software architecture: 1. Linux Kernel: The Linux kernel is the foundation of the Android operating system. It provides core system services such as memory management, process management, security, and device drivers. 2. Hardware Abstraction Layer (HAL): The HAL provides a standardized interface between the Android platform and the underlying hardware. It allows developers to write hardware-specific code without needing to know the details of the hardware. 3. Native C/C++ Libraries: The native libraries include a set of libraries that provide core system functionalities such as graphics rendering, media playback, and networking. 4. Android Runtime: The Android runtime includes the Dalvik Virtual Machine (DVM) and the Android Runtime (ART). The DVM is used to execute Android applications, while ART is a more recent runtime that provides improved performance and other optimizations. 5. Framework Layer: The Framework layer provides a set of APIs and services that application developers can use to build their applications. This layer includes a wide range of functionalities such as UI rendering, data storage, location services, and more. 6. Applications: Finally, the top layer of the Android software architecture is the applications layer. This layer includes all the user-facing applications that users interact with, such as messaging apps, social media apps, games, and more. Overall, the Android software architecture is designed to be modular and flexible, allowing developers to build applications that take advantage of the underlying system functionalities while remaining independent of the specific hardware and software configuration of the device.
