illegal state exception cause fragment not attached with activity

Question

I am facing an issue when I am trying to move from fragment to activity but it's showing below stack trace. Why getActivity() not getting reference in Fragment.And the main thing is next activity is called but when I am taking intent action on next activity to another activity then it's showing this error.

I am attaching MainActvity by below lines previously when I am not attaching an activity to this fragment then it is showing getActivity() == null.

public MainActivity activity;

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

    }

Below is my code for Intent. Here I am changing from fragment to activity. I also registered this activity in maniest too.

readData(new MyCallback() {
                    @Override
                    public void onCallback(double value, double lng, String gymName) {
                        if (distance(value, lng, location.getLatitude(), location.getLongitude()) <= 0.1) {
                            LocalDate localDate = new LocalDate();
                            String date1 = localDate.toString();
                            DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference().child("Users").child(FirebaseAuth.getInstance().getCurrentUser().getUid());
                            databaseReference.child("checkInStatus").setValue("1");
                            databaseReference.child("checInDate").setValue(date1);
                            databaseReference.keepSynced(true);
                            Intent intent = new Intent(activity, CheckOutActivity.class);
                            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                            intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                            startActivity(intent);
                        } else {
                            final Snackbar snackbar = Snackbar
                                    .make(coordinatorLayout, getString(R.string.not_at_gym_location), Snackbar.LENGTH_LONG)
                                    .setAction("DISMISS", new View.OnClickListener() {
                                        @Override
                                        public void onClick(View view) {

                                        }
                                    });
                            snackbar.setActionTextColor(Color.BLACK);
                            // Changing action button text color
                            View sbView = snackbar.getView();
                            sbView.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.orange_bt));
                            TextView textView = sbView.findViewById(android.support.design.R.id.snackbar_text);
                            textView.setTextColor(Color.WHITE);

                            snackbar.show();
                        }
                    }
                });

Please help me out. I am not getting how to resolve this I searched on other posts but not helpful.

you are trying to start activity when fragment is already detaced from activity (ha sbeen replaced or removed), or the activity itself is not in foreground. — Vladyslav Matviienko, Jul 25 '18 at 10:37

@RajshreeTiwari I have already gone through that link that's not solved my problem — Divyank Vijayvergiya, Jul 25 '18 at 10:41
`what is the solution` to rework your app ligic the way you don't start another activity from the fragment, which is already detached. It is too broad to ask for the code. — Vladyslav Matviienko, Jul 25 '18 at 10:43
