Apps What is the difference android and androidx

[Kurniawan]

Hai i just learn about android developement, why i can't add despendencies support.
example if i add this despendencies :

implementation 'com.android.support:cardview-v7:28.0.0'

Always out notification:

Version 28 (intended for Android Pie and below) is the last version of the legacy support library, so we recommend that you migrate to AndroidX libraries when using Android Q and moving forward. The IDE can help with this: Refactor > Migrate to AndroidX... less... (Ctrl+F1)

So i must migrate to androidx, and then despendencies change to :

implementation 'androidx.cardview:cardview:1.0.0'

Because if i learn on tutorial, always use android not androidx, but i can't use android despendencies.
Thanks

Yes, I come across the same problems. This post may help to explain the differences. I'm sure others here will have a better explanation.
