Hilt NullPointerException onAttach by Preconditions.checkNotNull on Fragment

Question

I have fragment which extend Fragment and I' m getting hilt error

java.lang.NullPointerException
        at dagger.hilt.internal.Preconditions.checkNotNull(Preconditions.java:34)
        at dagger.hilt.android.internal.managers.ViewComponentManager$FragmentContextWrapper.<init>(ViewComponentManager.java:191)
        at dagger.hilt.android.internal.managers.FragmentComponentManager.createContextWrapper(FragmentComponentManager.java:105)
        at main.Hilt_MyListFragment.initializeComponentContext(Hilt_MyListFragment.java:60)
        at main.Hilt_MyListFragment.onAttach(Hilt_MyListFragment.java:53)
        at androidx.fragment.app.Fragment.onAttach(Fragment.java:1881)
        at lv.inbox.mailapp.widget.InboxFragment.onAttach(MyFragment.java:63)

MyFragment class:

abstract public class MyFragment extends Fragment {
    @Override
    public void onAttach(Context context) {
        super.onAttach(LanguageContextWrapper.create(context, LanguageContextWrapper.getUserPreferLanguage(context)));
        this.context = context;
    }
}

How to solve my error?

Answer 1

this.context must be first

    @Override
    public void onAttach(Context context) {
        this.context = context;
        super.onAttach(LanguageContextWrapper.create(context, LanguageContextWrapper.getUserPreferLanguage(context)));
    }
