What is the purpose of Android Jetpack?

Android Jetpack is a collection of libraries and tools designed for developing Android applications. Its purpose is to assist developers in easily building high-quality applications, increasing development speed, and reducing common development errors.

Android Jetpack offers a series of components, including:

1. Architecture Components: These components offer guidelines and libraries for building robust, testable, and easily manageable application architectures, such as Room (for database access), LiveData (for reactive UI), and ViewModel (for storing and managing UI-related data).
2. UI components: Android Jetpack offers a range of components for building beautiful and smooth user interfaces, such as RecyclerView (for efficiently displaying list data), ViewPager2 (for creating swipeable pages), Paging (for handling paginated loading of large datasets), and more.
3. Basic components: These components offer commonly used functions such as notifications, permission management, and shared data storage to simplify the development process.
4. Behavior components: These components offer implementations of common user interaction behaviors, such as navigation, sidebar menus, gestures, etc., to provide a better user experience.

In general, the purpose of Android Jetpack is to streamline the Android application development process by providing a standardized set of tools and components, increasing development efficiency, and helping developers build high-quality applications.
