What is Jetpack in Android and why Android developer should have to use Jetpack.

Android Jetpack:

What's new in Jetpack:
Android Jetpack comes with five new components:

  1.     WorkManager alpha release
  2.     Navigation alpha release
  3.     Paging stable release
  4.     Slices alpha release
  5.     Android KTX (Kotlin Extensions) alpha release


According to Android officials 

"Jetpack is a suite of libraries to help developers follow best practices, reduce boilerplate code and write code that works consistently across Android versions and devices so that developers can focus on the code they care about. "

Let's Understand what actually it is.

Jetpack: Architecture 

The Architecture zone of Jetpack incorporates eight unique libraries and instruments that help you, modeler, your application and deal with the information utilized by and showed in the application. A large portion of these are existing libraries. In any case, there are three new libraries: 
  1. Navigation, 
  2. Paging, and 
  3. WorkManager. 
What is Android Jetpack? 

Android Jetpack is an assortment/collection of Android programming components which encourages us in building incredible Android applications. 
The Android Jetpack components bring together the existing Support Library and Architecture Components and arrange them into four categories.
These software components help in:

  • Following the prescribed procedures and composing the standard code. 
  • Making complex things basic. 

Prior there were numerous difficulties which are as per the following: 

  •     Managing activity lifecycles.
  •     Surviving configuration changes.
  •     Preventing memory leaks.
All these serious issues have been tackled by the Android Jetpack's software components. 

Thus, the answer to all the issues is Andriod Jetpack. 

Another most significant thing about the Jetpack is that it gets refreshed more often than the Android stage with the goal that we generally get the most recent version. 

Jetpack contains the androidx.* bundle libraries, unbundled from the stage APIs. This implies it offers in reverse compatibility.

Android Jetpack Components 

Android Jetpack components are an assortment of libraries that are exclusively adaptable and worked to cooperate while exploiting Kotlin language includes which makes us more beneficial. 

These software segments have been orchestrated in 4 classes which are as per the following: 

  1. Foundation Components 
  2. Architecture Components 
  3. Behavior Components 
  4. UI Components 

How about we see individually.

Foundation Components

The foundation components give the accompanying: 

  • Backward compatibility 
  • Testing 
  • Kotlin language support. 

All the foundation components are as per the following: 

Application Compat: Degrade nimbly on more established forms of Android with material design UI execution support. 

Android KTX: Set of Kotlin expansions to compose more compact, colloquial Kotlin code. 

Multidex: Provide support for various dex documents for applications. 

Test: A testing system for unit and runtime UI tests in Android.

Architecture Components 

The Architecture Components help us in the building: 

  • Powerful/Robust  Apps 
  • Testable Apps 
  • Viable/Maintainable  Apps 

All the architecture components are as per the following: 

Data Binding: Declaratively tie UI components to in our layout to the data source of our application. 

Lifecycles: Manages activity and fragments lifecycles of our application. 

LiveData: Notify perspectives views on any database changes. 

Route: Handle everything required for the in-application route. 

Paging: Gradually load data on request from your information source. 

Room: Fluent SQLite database gets to. 

ViewModel: Manage UI-related information in a lifecycle-cognizant way. 

WorkManager: Manage each background job in Android with the conditions we pick.


Behavior Components 

The Behavior Components help in the implementation with standard Android services like 

  • Notifications
  • Permissions
  • Sharing 
  • Assistant

All the conduct components are as per the following: 

Download Manager: Schedule and oversee enormous downloads in background with auto-retry support. 

Media and playback: Backwards perfect APIs for media playback and directing (including Google Cast). 

Notifications: Provides a retrogressive good Notifications API with Wear and Auto support. 

Permissions: Compatibility APIs for checking and mentioning authorizations in the application. 

Preferences: Create intelligent settings screens for clients to design. 

Sharing: Provides an offered activity appropriate for an application's activity bar. 

Slices: Create adaptable UI components that can show application information outside the application and can be stretched out right back to Android 4.4.

UI Components 

The UI components give gadgets and assistants to make your application simple, yet magnificent to utilize. 

All the UI parts are as per the following: 

Animation and transitions: Move gadgets and change between screens. 

Auto: Components to create Android Auto applications. 

Emoticon: Enable refreshed emoticon text style on more seasoned stages. 

Fragment: A fundamental unit of composable UI. 

Design: Layout gadgets with various algorithms. 

Palette: Pull valuable data from shading palettes. 

Television: Components to create Android TV applications. 

Wear: Components to create Wear applications.

=============================

That's all about Jetpack.
Thanks for being here.
