Can a Fragment getContext() return null when isResumed() is returning true

Question

In my code, I am displaying a Toast after a network request callback.

Since Toast requires a Context, I am first checking if the Fragment is in the resumed state isResumed() before doing the getContext() call inside the Toast.

I am getting IllegalStateException with Fragment not attached to a context error pointing to that line of code where I display the Toast

So my question is, how come getContext() can return null and the fragment is in the resumed state?

Note: As a solution I have added another isAdded() check.

*Can a Fragment getContext() return null when checking isResumed()* **Yes** if you activity is not attached with fragment in that case it will return `null` — AskNilesh, Apr 25 '19 at 06:59
@NileshRathod Well this is my point. I am checking if Fragment isResumed which means visible (resumed state). How can it be resumed and in the same time not attached to a context? — TareK Khoury, Apr 25 '19 at 07:04
@TareKKhoury try to use [`onAttach(Context context)` to get `Context`](https://stackoverflow.com/a/52732620/7666442) — AskNilesh, Apr 25 '19 at 07:07
@VladyslavMatviienko nothing to share, pretty simple `if(isResumed())` check and display a `Toast` inside — TareK Khoury, Apr 25 '19 at 07:08
@NileshRathod I have solved the error. My question is for me to understand how come getContext() is null while isResumed() returns true :) — TareK Khoury, Apr 25 '19 at 07:09
yes, might be it returns null, I m suggesting that don't use ```getContext()```, use ```getActivity()``` instead — Priyanka, Apr 25 '19 at 07:22
@Priyankagb They are the same. both return the Activity hosting the Fragment — TareK Khoury, Apr 25 '19 at 07:38

Use this.

public class yourFragment extends Fragment {
   Context context

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

   @Override
   public void onDetach() {
        super.onDetach();
        this.context = null;
   }
}
