Youtube player support fragment no longer working on Android studio 3.2 (androidx)

Question

I just updated my Android Studio to version 3.2 and followed instructions to use androidx.

I've been using a Youtube fragment inside a Fragment activity and everything worked perfectly but, after the update, these 3 simple lines now give me the error "Cannot resolve method 'add(...)'":

YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();

...and when i try to use "replace" instead of "add" it says: "Wrong 2nd argument type. Found: 'com.google.android.youtube.player.YouTubePlayerSupportFragment', required: 'androidx.fragment.app.Fragment'"

...which makes me think that the problem has to do with the new AndroidX feature.

The problem is that the add method wants the second parameter of type:

androidx.fragment.app.Fragment

...but the YouTubePlayerSupportFragment returns a:

android.support.v4.app.Fragment

Does anyone know how to solve this problem? Is there a way to cast the "android.support.v4.app.Fragment" into the "androidx.fragment.app.Fragment"?

Answer 1

Just use transaction.replace. Ignore the error, it'll work. Google hasn't refactored youtube api library to androidx yet.
