Why won't androidx support the navigation bar?

Question

So I\'m trying to get a navigation drawer done using this tutorial (https://www.youtube.com/watch?v=fGcMLu1GJEc&t=16s) however, I undersetand that something has changed in A

Answer 1

AndroidX replaces the original support library APIs with packages in the androidx namespace.

Looks like you are using some of the support library classes in your xmls as you can see in the logs:

Didn't find class "android.support.v4.widget.DrawerLayout" on path: DexPathList
    android.support.v4.widget.DrawerLayout

In your xml that is being inflated in the MainActivity, replace this:

android.support.v4.widget.DrawerLayout

with this:

androidx.drawerlayout.widget.DrawerLayout

This should solve this error for you.

However, I am positive there will be more xmls with older support library classes. Refer here and search for the class causing the error as above and replace it with the corresponding androidx class.
