Previously I was using android.app.Fragment which provided ComponentCallbacks2. I am now migrating my app to use androidx Fragment. However it says 'onTrimMemory overrides nothing'. I look and see that androidx Fragment only provides ComponentCallbacks. Is there any way to workaround and get the level int?

You can implement ComponentCallbacks2 in your Fragment and register it using Context.registerComponentCallbacks:
public class MyFragment extends Fragment implements ComponentCallbacks2 {
@Override
public void onAttach(@NonNull Context context) {
super.onAttach(context);
context.registerComponentCallbacks(this);
}
@Override
public void onDetach() {
requireContext().unregisterComponentCallbacks(this);
super.onDetach();
}
@Override
public void onTrimMemory(int level) {
}
}
