What is Android Jetpack and why should we use it?
Jetpack is a group of Android software components to make it easier for you to develop considerable Android apps. These components help you support best practices, free you from writing boilerplate code, and simplify complex tasks, so you can focus on the code you are concerned about.
Jetpack contains the androidx. package libraries, unbundled from the platform APIs. This means that it gives backward compatibility and is updated more repeatedly than the Android platform, making sure you always have the interface with the latest and greatest versions of the Jetpack components.
Jetpack is divided into four main areas: Architecture, Foundation, Behavior, and UI. Most of the items in Jetpack are systematically organized and categorized using existing libraries, but a few of the items are new.
Android Jetpack Components
Android Jetpack components are a collection of libraries that are individually adaptable and built to work together while taking advantage of Kotlin language features that make you more useful.
Foundation components deliver cross-cutting functionality like backward compatibility, testing, and Kotlin language support.
All the foundation components are as follows:
Degrade easily on older versions of Android
Write better concise, idiomatic Kotlin code
Provide support for apps along with multiple DEX files
An Android testing framework intended for unit and runtime UI tests
Architecture components, basically help design robust, testable and maintainable apps.
Definitely, bind observable data to UI elements
Organize your activity and fragment lifecycles
Notify views while underlying database changes
Handle everything essential or needed for in-app navigation
Systematically load information on demand from your data source
Effortless SQLite database access
Manage UI-related data in a lifecycle– sensible way
Handle your Android background jobs.
Behavior components help your app combine with standard Android services like notifications, permissions, sharing and the Assistant.
Download manager organize and manage large downloads
Backward compatible APIs especially for media playback and routing (including Google Cast)
Provides a backward-compatible notification API supportive with Wear and Auto
Compatibility APIs all for checking and requesting app permissions
Construct interactive settings screens
Provides a share action suitable meant for an app’s action bar
Create flexible UI elements a particular that can display app data outside the app
UI components provide widgets and helpers to make your app not only easy, but fabulous to use.
Advanced widgets and transition between screens
Components to assisting develop apps for Android Auto
Permit an up-to-date emoji font on older platforms
A key and fundamental unit of composable UI
Layout widgets applying different algorithms
Pull purposeful information out of color palettes
Components supporting to develop apps for Android TV
Components to help develop apps design for Wear
In this article, you were introduced with the four main parts of Jetpack. Some of the new libraries, like the Navigation library, will change the way you write your apps, making it easier than ever, which is also developed by Andriod app development Melbourne.
