What is AndroidX?

Question

I am reading about a room library of Android. I see they changed package android to androidx. I did not understand that. Can someone explain, pleas

Answer 1

androidx will replace support library after 28.0.0. You should migrate your project to use it. androidx uses Semantic Versioning. Using AndroidX will not be confused by version that is presented in library name and package name. Life becomes easier
