Android Jetpack is a set of components, tools and guidance to make great Android apps.

Introduction

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.

Libraries Used

• 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
