Android Jetpack is a set of components, tools and guidance to make great Android apps. They bring together the existing Support Library and Architecture Components and arrange them into four categories.
- Foundation - Components for core system capabilities, Kotlin extensions and support for
multidex and automated testing.
- AppCompat - Degrade gracefully on older versions of Android.
- Android KTX - Write more concise, idiomatic Kotlin code.
- Test - An Android testing framework for unit and runtime UI tests.
- Architecture - A collection of libraries that help you design robust, testable, and
maintainable apps. Start with classes for managing your UI component lifecycle and handling data
persistence.
- Data Binding - Declaratively bind observable data to UI elements.
- Lifecycles - Create a UI that automatically responds to lifecycle events.
- LiveData - Build data objects that notify views when the underlying database changes.
- Navigation - Handle everything needed for in-app navigation.
- Room - Access your app's SQLite database with in-app objects and compile-time checks.
- ViewModel - Store UI-related data that isn't destroyed on app rotations. Easily schedule asynchronous tasks for optimal execution.
- WorkManager - Manage your Android background jobs.
- UI - Details on why and how to use UI Components in your apps - together or separate
- Animations & Transitions - Move widgets and transition between screens.
- Fragment - A basic unit of composable UI.
- Layout - Lay out widgets using different algorithms.
- Third party and miscellaneous libraries
- Glide for image loading
- Hilt: for dependency injection
- Kotlin Coroutines for managing background threads with simplified code and reducing needs for callbacks
