There are several developers facing issues with androidx migration as well as they are confused why should they migrating to androidx. ?

In this article we are trying to find the solutions for those questions. What is androidX, importance of AndroidX and How to migrate to AndroidX. ?

What is Android X .?

Simply we can say, AndroidX is the open-source project that the Android team uses to develop, test, package, version and release libraries within Jetpack. AndroidX is a major improvement to the original Android Support Library.

AndroidX is a major improvement to the original Android Support Library. Like the Support Library, AndroidX ships separately from the Android OS and provides backwards-compatibility across Android releases. AndroidX fully replaces the Support Library by providing feature parity and new libraries.

AndroidX includes the following features:

All packages in AndroidX live in a consistent namespace starting with the string androidx. The Support Library packages have been mapped into corresponding androidx.* packages. For a full mapping of all the old classes and build artifacts to the new ones, see the Package Refactoring page.

Unlike the Support Library, AndroidX packages are separately maintained and updated. The androidx packages use strict Semantic Versioning starting with version 1.0.0. You can update AndroidX libraries in your project independently.

All new Support Library development will occur in the AndroidX library. This includes maintenance of the original Support Library artifacts and introduction of new Jetpack components.

What is the importance of Migrating to android X . ?

The support library artifacts are being deprecated and all future development is going into AndroidX, so there’s no point to avoiding this migration.

Particularly pertinent to developers was how they repackaged all the libraries. Not only have their maven coordinates changed, but the package names for every class has changed as well.

For example:-

android.support.v7.app.AppCompatActivity is now androidx.appcompat.app.AppCompatActivity.

The old artifacts and package names were a confusing mess, so in the long run this is a great move. In the short-term, though, upgrading requires extensive changes to your codebase.

Theoretically, this migration should be as easy as running the “Migrate to AndroidX” tool in Android Studio.
