AndroidX is a replacement / refactoring of Android Support Library. It was announced at Google I/O 2018 as alpha, and recently the stable version of it was officially released. Since Android Support Library v28 is the last version as a target to be maintained and afterward all the feature additions and bug fixes will be added to AndroidX, it is crucial for Android developers to migrate from Support Library to AndroidX.
In this talk, I have talked briefly about what AndroidX is, why Support Library needed to be refactored and re-polished as AndroidX, and finally how we can migrate to AndroidX.
