Android Framework
The Android Framework is a set of software libraries and tools provided by Google that enable developers to create applications for the Android operating system. It includes a wide range of components that handle common tasks such as user interface, networking, data storage, and multimedia support.
The Android Framework is built on top of the Java programming language and includes the Dalvik Virtual Machine, which is optimized for mobile devices with limited memory and processing power. The Android Framework provides a high-level API that allows developers to interact with the underlying hardware and operating system without needing to write low-level code.
Some of the key components of the Android Framework include:
Activity Manager: It manages the lifecycle of applications and controls the activity stack.
Content Providers: It manages access to structured data such as a database.
Resource Manager: It provides access to non-code resources such as strings, graphics, and layout files.
Notification Manager: It provides support for displaying notifications to the user.
View System: It provides the building blocks for creating user interfaces, such as buttons, text fields, and layouts.
Location Manager: It provides access to the device’s location sensors such as GPS, Wi-Fi, and cellular networks.
Media Framework: It provides support for playing and recording audio and video.
Wi-Fi Manager: It provides access to the device’s Wi-Fi radio, allowing applications to scan for available networks and connect to them. The Android Framework provides a powerful and flexible platform for developing mobile applications. By leveraging the pre-built components of the Framework, developers can quickly and easily create high-quality applications that run on a wide range of Android devices.
