Android Application crashes when I switch to a fragment after I tried implementing Firebase Realtime Database

I had it working with SQLite database but then when I tried to switch to Firebase Real-time Database it decided to start crashing on me… I’m completely lost on this one. Some help would be much appreciated.

Here is my Firebase data

Registered Users

gender: "Male"
mobile: "2042322553"

You might also want to look at the RecyclerViewAdapter

package com.example.goalhero;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;

    private DatabaseReference dailiesDatabaseReference;
    private boolean isUpdating = false;

    public RecyclerViewAdapterDailies(Context context, ArrayList<DataDaily> dailies) {
        this.context = context;
        this.dailies = dailies;

        FirebaseDatabase database = FirebaseDatabase.getInstance();
        dailiesDatabaseReference = database.getReference("dailies");
    }

    public void setDailies(ArrayList<DataDaily> dailies) {
        this.dailies = dailies;
        notifyDataSetChanged();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        private CheckBox dailyListItemCB;
        private TextView dailyTextView;
        private ImageView deleteImage;
        private RelativeLayout parent;

        public ViewHolder(@NonNull View itemView) {

        }
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.dailies_list_item, parent, false);
        return new ViewHolder(view);
    }

    @Override

        final DataDaily currentDaily = dailies.get(position);

        holder.dailyListItemCB.setText(currentDaily.getInfo());
        if (currentDaily.getTimeFrame() != null && !currentDaily.getTimeFrame().isEmpty()) {
            holder.dailyTextView.setText(currentDaily.getTimeFrame());
        } else {
            holder.dailyTextView.setText("");
        }

        holder.dailyListItemCB.setChecked(currentDaily.isCompletedToday());

        holder.dailyListItemCB.setOnCheckedChangeListener((buttonView, isChecked) -> {
            if (!isUpdating) {
                currentDaily.setCompletedToday(isChecked);
                updateCompletionStatusInFirebase(currentDaily);

                Random random = new Random();
                int randomNumber = random.nextInt(10) + 1;
                if (randomNumber == 10 && context instanceof ActivityMain) {
                    ((ActivityMain) context).showPopupWindow();
                }
            }
        });

        holder.deleteImage.setOnClickListener(v -> deleteDailyFromFirebase(currentDaily));
    }

    @Override
    public int getItemCount() {
        return dailies.size();
    }

    private void updateCompletionStatusInFirebase(DataDaily daily) {
        isUpdating = true;
        dailiesDatabaseReference.child(daily.getKey()).setValue(daily)
                .addOnCompleteListener(task -> {
                    if (task.isSuccessful()) {
                        Toast.makeText(context, "Status updated successfully", Toast.LENGTH_SHORT).show();
                    } else {
                        Toast.makeText(context, "Status update failed", Toast.LENGTH_SHORT).show();
                    }

                    }
                });
    }
}

Here is my data daily class…

package com.example.goalhero;

public class DataDaily {
    private String key; // This will store the Firebase key
    private String dailyID;
    private boolean mon, tues, wed, thurs, fri, sat, sun, completedToday, isEasy;
    private String title, timeFrame, reps;

    // Default constructor required for calls to DataSnapshot.getValue(DataDaily.class)

    public DataDaily(boolean mon, boolean tues, boolean wed, boolean thurs, boolean fri,
                     boolean sat, boolean sun, boolean completedToday, boolean isEasy,
                     String title, String timeFrame, String reps) {
        this.mon = mon;
        this.tues = tues;
        this.wed = wed;
        this.thurs = thurs;
        this.fri = fri;
        this.sat = sat;
        this.sun = sun;
        this.completedToday = completedToday;
        this.isEasy = isEasy;
        this.title = title;
        this.timeFrame = timeFrame;
        this.reps = reps;
    }

    public DataDaily() {}

    // Getters and setters for all member variables
    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }
    public boolean isMon() {
        return mon;
    }

    public void setMon(boolean mon) {
        this.mon = mon;
    }

    public boolean isTues() {
        return tues;
    }

    public void setTues(boolean tues) {
        this.tues = tues;
    }

    public boolean isWed() {
        return wed;
    }

    public void setWed(boolean wed) {
        this.wed = wed;
    }

    public boolean isThurs() {
        return thurs;
    }

    public void setThurs(boolean thurs) {
        this.thurs = thurs;
    }

    public boolean isFri() {
        return fri;
    }

    public void setFri(boolean fri) {
        this.fri = fri;
    }

    public boolean isSat() {
        return sat;
    }

    public void setSat(boolean sat) {
        this.sat = sat;
    }

    public boolean isSun() {
        return sun;
    }

    public void setSun(boolean sun) {
        this.sun = sun;
    }

    public boolean isCompletedToday() {
        return completedToday;
    }

    public void setCompletedToday(boolean completedToday) {
        this.completedToday = completedToday;
    }

    public boolean isEasy() {
        return isEasy;
    }

    public void setEasy(boolean easy) {
        isEasy = easy;
    }

    public String getDailyName() {
        return title;
    }

    public void setDailyName(String dailyName) {
        this.title = dailyName;
    }

    public String getTimeFrame() {
        return timeFrame;
    }

    public void setTimeFrame(String timeFrame) {
        this.timeFrame = timeFrame;
    }

    public String getRepetitions() {
        return reps;
    }

    public void setRepetitions(String repetitions) {
        this.reps = repetitions;
    }
public String getDailyID() {
    return dailyID;
}

public void setDailyID(String dailyID) {
    this.dailyID = dailyID;
}

public String getInfo() {
    return reps + "x " + title;
}

}

Here’s what I believe to be the error causing the application to stop working…

I’m completely lost here I just started using Firebase so I have no
idea… Also I’m a newbie to programming.

I don’t even know where to put debig statements so any help would be appreciated…
