The class "android.app.DialogFragment" is deprecated in API 28. What should we use instead?

When creating the class "AlertDialogFragment" from the video, I was adding the superclass and Android Studio alerted me that the class "android.app.DialogFragment" was deprecated in API 28. Obviously it still works, but I was wondering what should be used instead?

This is the documentation, I'm just not sure what I'm looking at: https://developer.android.com/reference/android/app/DialogFragment

Hi Michael! It just wants you to use the version of that class from the support library. Try changing 'android.app.DialogFragment' to 'android.support.v4.app.DialogFragment'.

Let me know if that doesn't work!

Hey Kamran! You'll need to override the 'onCreateDialog' function. Here's a link to the docs if it helps: https://developer.android.com/reference/android/support/v4/app/DialogFragment.html#onCreateDialog(android.os.Bundle)

Looks like if you're using the latest libraries, you actually want

import androidx.fragment.app.DialogFragment;

(see this SO post for details)
