Currently, It is recommended by Google to use AndroidX in our project to make it compatible with many Android versions.

"AndroidX is a major improvement to the original Android Support Library, which is no longer maintained.androidx packages fully replace the Support Library by providing feature parity and new libraries." (link)

Is there a price for that? Let's consider the following points...

Simple Hello World with 'androidx"

• APK Size: 1.6 MB;
• AndroidX Size has ~1.5 MB;
• It has >10K methods (remembering in enabling the multi-dex if your app exceeds over 64K methods).

Simple Hello world without 'androidx'

• APK Size has 102.7 KB.

Keep in mind: A dependency always has a price in a project and I think this should be taken into consideration before using it.

Just think about!
