Why does my app crash when I click items in a Fragment class?

Question

When I go to click an item in the SettingsFragment, my app crashes. Everything is displayed properly in this fragment class but only my parseUrl items work. i click on any other items and my app just closes out. Why does that happen? Below is my code.

public class SettingsFragment extends Fragment {
MainActivity context;


public SettingsFragment() {
    //public constructor
}

@NonNull
@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.navigation_drawer, container, false);


    FrameLayout instructions = view.findViewById(R.id.instructions);
    if (!getInstance().get("INSTRUCTIONS_ACTIVE", true)) {
        instructions.setVisibility(View.GONE);
    }
    instructions.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            openInstructions();

        }
    });


    return view;

}

// Main functions
void openInstructions(){
    Intent transactions = new Intent(context, FragmentsActivity.class);
    transactions.putExtra("show","instructions");
    startActivity(transactions);
}


public void settingsMenu(String Type){

    switch (Type) {



        case "instructions":

            openInstructions();

            break;

}

Answer 1

It seems that the context is null
Use getContext() or getActivity() inside onCreateView to initialize the context

Answer 2

context is not initialized, one way to do that is to add this method:

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