Audio is not played on Android Studio

Question

I am using Android Studio with MacBook, and copied and pasted an audio file in raw folder.

The audio file(mp3) which I want to use is 10.3MB, so Android Studio says, "The file size exceeds configured limit. Code insight features are not available." And, I resized the audio file with a random resizer online. However, when I resize the file, Android Studio says, "File was loaded in the wrong encoding: 'UTF-8'".

Now, I tried everything that I could find in stack overflow. I turned off bluetooth and stuff like that... Also, I deleted cache with:

~/Library/Preferences/AndroidStudio[Preview]_X.Y_
~/Library/Caches/AndroidStudio[Preview]_X.Y_
~/Library/Logs/AndroidStudio[Preview]_X.Y_
~/Library/Application Support/AndroidStudio[Preview]_X.Y_

Are there any advises? It seems like it would work on windows to just copy and paste an audio file in raw folder, but I am using Mac, so it's not working. This is how I thought.

Have you tried playing the audio using something similar to this code as recommended by the Android Developers page?

// am1n
import androidx.appcompat.app.AppCompatActivity;
import android.media.AudioAttributes;
import android.media.MediaMetadataRetriever;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import java.io.File;
import java.io.IOException;

public class TestAudioActivity extends AppCompatActivity
{
    private String filepath;
    private File audioFile;
    private Uri audioUri;
    private MediaMetadataRetriever mediaMetadataRetriever;
    int audioDuration;
    private MediaPlayer mediaPlayer;
    private TextView audioTitle;
    private ImageView audioCloseButton;

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

        filepath = getIntent().getStringExtra("ITEMPATH");
        audioFile = new File(filepath);
        audioUri = Uri.fromFile(audioFile);

        // Getting audio duration in milliseconds.
        mediaMetadataRetriever = new MediaMetadataRetriever();
        mediaMetadataRetriever.setDataSource(getApplicationContext(), audioUri);
        audioDuration = Integer.parseInt(mediaMetadataRetriever.extractMetadata(mediaMetadataRetriever.METADATA_KEY_DURATION));
        Toast.makeText(getApplicationContext(), audioDuration + "", Toast.LENGTH_SHORT).show();

        mediaPlayer = new MediaPlayer();
        mediaPlayer.setAudioAttributes(new AudioAttributes.Builder().setContentType(AudioAttributes.CONTENT_TYPE_MUSIC).setUsage(AudioAttributes.USAGE_MEDIA).build());
        try
        {
            mediaPlayer.setDataSource(getApplicationContext(), audioUri);
            mediaPlayer.prepare();
            mediaPlayer.start();
        }
        catch(IOException e)
        {
            finish();
            e.printStackTrace();
        }

        audioTitle = findViewById(R.id.audio_title);
        audioCloseButton = findViewById(R.id.audio_close_button);
        audioCloseButton.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                closeAudio();
            }
        });
    }

    // Audio file must be closed after job is done.
    public void closeAudio()
    {
        mediaPlayer.release();
        mediaPlayer = null;
        finish();
    }

    @Override
    public void onBackPressed()
    {
        closeAudio();
    }
}
