When trying to read File while testing on Android Studio the application just closes

So I've been working on an App that tells you random topics to talk about. I try to read in a File and show a Text with a random Topic that was on the File. My code to do this is here:

package com.example.nosir;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.List;
import android.util.Log;
import java.util.Random;



public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    public static final String TAG = MainActivity.class.getSimpleName();
    public static final String mPath = "example.txt";
    private QuoteBank mQuoteBank;
    private List<String> mLines;
    Random random = new Random();

    TextView text1;
    String theTopic;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button button1 = findViewById(R.id.button1);
        button1.setOnClickListener(this);
        text1 = (TextView) findViewById(R.id.text1);

        mQuoteBank = new QuoteBank(this);
        mLines = mQuoteBank.readLine(mPath);
        for (String string : mLines)
            Log.d(TAG, string);

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button1:
                text1.setText(mLines.get(random.nextInt(mLines.size())));
                break;
            default:

                break;
        }
    }


}

package com.example.nosir;

import android.content.Context;
import android.content.res.AssetManager;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.List;
import java.util.ArrayList;

public class QuoteBank {

    private Context mContext;

    public QuoteBank(Context context) {
        this.mContext = context;
    }

    public List<String> readLine(String path) {
        List<String> mLines = new ArrayList<>();

        AssetManager am = mContext.getAssets();

        try {
            InputStream is = am.open(path);
            BufferedReader reader = new BufferedReader(new InputStreamReader(is));
            String line;

            while ((line = reader.readLine()) != null)
                mLines.add(line);
        } catch (IOException e) {
            e.printStackTrace();
        }

        return mLines;
    }
}

But when I press the button to show the random Text, my application just closes and does nothing. I'm testing on a OnePlus6. I really don't know what's the issue. I hope that somebody can help me. Thanks in advance.
