Why is Jetpack a Fast, Productive and Efficient Application?

Google recently announced, Jetpack (a toolkit to create fast, productive, and efficient applications). In general, Jetpack includes an updated AppCompat, an extension of Kotlin Android KTX, and architectural components such as ViewModel, and Room.  Additionally, there are Android APIs in the list, such as the Emoji Manager.  In addition, Jetpack retains the backward compatibility of Android versions.

Work Manager

Among the components of Jetpack, it is worth mentioning WorkManager, which replaced the AsyncTask, JobScheduler. WorkManager is an Android library. It allows you to run background tasks at a specific time, in a certain sequence, under certain conditions. You can use WorkManager to transfer data to an executable and get results from it. WorkManager has a number of advantages, for example it does not require Google Play on the device. Additionally, you can run tasks only under conditions of execution, and you can create task chains.

Paging Library

With the help of the new Paging component, the RecyclerView flaw can be overcome. The task of the library is to work with lists. With Paging Library, the work of splitting content into pages becomes easy, since it comes with that implementation out of the box. Additionally, the component is able to work on loading data from multiple sources with subsequent mixing.

Slices

Additionally, Google added the Slices component to Jetpack. In Slices, you can display functions that are related to the type of program and its capabilities. You can distinguish three groups of functions: navigation, task execution, return to data. In general, from Slices, users get easier and quicker interaction, and developers can get more traffic and the ability to turn the user into an application.

Navigation

In Android, navigation has always been powerful and diverse: Activity, Fragment, yet DeepLinks needs to be processed and followed by arguments passed.  The new Navigation component, which is also built into Android Studio, specifically solves the issue of confusion when viewing a large map of the screens. In Navigation, DeepLinks is handled with the support of the entire tree of transitions.

Jetpack today is a collection of useful libraries in one place that can make a developer’s life a bit easier and coding more enjoyable.  For example, developers can choose only the components they need because the components are not bundled. Google plans to release new Jetpack components in hopes that developers will be able to add them and deploy the update in a single day.
