Make sure you guys are using android.app imports and not android.support imports. This might be the issue you guys are facing.

hey i found the answer instead of creating object of ListFragment in main activity we have to create object of FragmentList class which we have created and pass that object

my java class is FragmentList so what i have done is

FragmentList list = new FragmentList(); . . .

fragmentTransaction.add(R.id.placeHolder,list); . .

In my activity.main I have this as my code. But please provide what you have in your listfragment.java as well.

ListFragment fragment = new ListFragment(); FragmentManager fragmentManager = getFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.add(R.id.placeholder, fragment); fragmentTransaction.commit();

There is no such class named FragmentList All i can find is ListFragment which was deprecated in API level 28

The ListFragment used in MainActivity.java has to be the same one as the one made in previous video. Since the ListFragment.java is in the same package, it does not need to be imported.

For some reason Android Studio tools had imported one of the ListFragment objects from the android libraries, and removing it fixed the issue for me - so anyone still having up with this issue should make sure to check if there is import android.support.v4.app.ListFragment or import android.app.ListFragment in their MainActivity class and remove it.
