Мое приложение для записи звука не может начать запись

Мое приложение выдает исключение IOException, когда я пытаюсь записать звук. java.io.FileNotFoundException: /storage/emulated/0/recording.3gp: ошибка открытия: EACCES (отказано в доступе). Это происходит внутри моего метода recordButton.SetOnClickListener, а точнее в части try-catch моего кода. Я действительно не знаю, почему это терпит неудачу, но у меня есть ощущение, что это как-то связано с моей строкой outputFile. Вот мой файл JAVA:

    package com.example.audiorecorder;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;

import android.Manifest;
import android.content.pm.PackageManager;
import android.media.MediaPlayer;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.os.Environment;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {

Button playBtn, recordBtn, stopBtn;

String outputFile;

MediaRecorder mediaRecorder;

private static final int REQUEST_RECORD_AUDIO_PERMISSION = 200;

private boolean permissionToRecordAccepted = false;
private String [] permissions = {Manifest.permission.RECORD_AUDIO};

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull         int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode){
        case REQUEST_RECORD_AUDIO_PERMISSION:
            permissionToRecordAccepted  = grantResults[0] == PackageManager.PERMISSION_GRANTED;
            break;
    }
    if (!permissionToRecordAccepted ) finish();

}


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

    ActivityCompat.requestPermissions(this, permissions, REQUEST_RECORD_AUDIO_PERMISSION);

    outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/recording.3gp";

    playBtn = findViewById(R.id.play_btn);
    recordBtn = findViewById(R.id.record_btn);
    stopBtn = findViewById(R.id.stop_btn);

    mediaRecorder = new MediaRecorder();

    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    mediaRecorder.setOutputFile(outputFile);


    recordBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            try{
                mediaRecorder.prepare();
                mediaRecorder.start();
                Toast.makeText(getApplicationContext(), "Recording started", Toast.LENGTH_LONG).show();
                System.out.println("IT TRIED RECORDING");
            } catch (IllegalStateException ise){
                System.out.println("FAIL RECORDING 1");
            } catch (IOException ioe){
                System.out.println("FAIL RECORDING 2");
            }

            System.out.println("ITS JUST PRESSING RECORD BUT NOTHING");

        }
    });

    stopBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            try{
                mediaRecorder.stop();
                mediaRecorder.release();
                mediaRecorder = null;
                System.out.println("IT TRIED STOPPING");

            } catch (Exception e){
                System.out.println("FAIL STOP 1");
            }

            Toast.makeText(getApplicationContext(), "Stop Recording", Toast.LENGTH_LONG).show();

        }
    });

    playBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            MediaPlayer mediaPlayer = new MediaPlayer();
            try {
                mediaPlayer.setDataSource(outputFile);
                mediaPlayer.prepare();
                mediaPlayer.start();
                Toast.makeText(getApplicationContext(), "Playing Audio", Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                // make something
            }
        }
    });

}
}
