FragmentManager and androidx FragmentManager : <p>I'm trying to setup in my app that is using androidX.</p>

<p>My problem is that when I try to work with PlaceAutocompleteFragment I get errors because it is a fragment from <code>android.app.fragment</code> and my parent fragment is an androidx fragment: <code>androidx.fragment.app.Fragment</code> so it uses a <code>androidx.fragment.app.FragmentManager</code>instead of a <code>android.app.FragmentManager</code>.</p>

<p>How can I work with "old" fragments in androidX?</p>
