Access assets in Fragment

I have a Font in my assets folder and I called it in my fragment like this:

Typeface custom_font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/myFont.otf");

But I got a lint warning saying that getAssets() may return null.

I did some research and found this question/answer. I'm currently already getting the activities context.

---

What I was thinking of doing is adding the following method in my Activity:

public static Typeface getMyFont(Activity context){
    return Typeface.createFromAsset(context.getAssets(),  "fonts/myFont.otf");
}

and then calling it from my fragment like this:

mTextView.setTypeface(Activity.getMyFont(getActivity()));

---

By doing the above I don't get any warnings, but I'm not sure if it is the correct way, so..

My Question is:
Should I ignore the lint warning? Should I do it like I done above or is there a correct way of doing it?

But I got a lint warning saying that getAssets() may return null.

in Fragments getActivity() can return null if the fragment is not currently attached to a parent activity,

Solution 1 : check that your activity in not null

 if(getActivity()!=null){
            Typeface custom_font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/myFont.otf");
 }

Solution 2 : you can use onAttach() to get context

public class BlankFragment extends Fragment {


    private Context mContext;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);

        mContext=context;
    }

    public BlankFragment() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        Typeface custom_font = Typeface.createFromAsset(mContext.getAssets(), "fonts/myFont.otf");

        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_blank, container, false);
    }

}
