Basic working of android application framework
The Android application framework is the backbone of the Android operating system. It is built upon the Linux kernel and provides the necessary tools and libraries to build and run applications on Android devices.
Here’s a basic working of the Android application framework:
Application Layer: At the topmost layer, the application layer provides the user interface and user experience for the Android applications. It includes various applications that users can download and install on their devices, including social media apps, gaming apps, and productivity apps.
Application Framework Layer: The application framework layer provides the APIs that developers use to build Android applications. These APIs are built on top of the core libraries and provide an abstraction layer for developers, so they don’t have to interact directly with the lower-level system components.
Core Libraries Layer: The core libraries layer provides the fundamental functions required for Android applications, including data storage, graphics rendering, networking, and multimedia playback. These libraries are written in Java and provide the foundation for the higher-level APIs.
Android Runtime Layer: The Android runtime layer includes the Dalvik virtual machine, which is responsible for executing the Android application code. The Dalvik virtual machine is optimized for mobile devices and provides a memory-efficient way to run Java code. Linux Kernel Layer: At the lowest layer, the Linux kernel provides the core operating system functionality, including memory management, process management, and device driver interfaces. The Android platform uses a modified Linux kernel that includes additional drivers and system services required for mobile devices.
