Answer 1

Hope you already found your answer but may be this is better and if you wants to try, Here is your solution use the following code to Read the MP3 file from the Specific Folder or All files,

First of all Create 1 Model class as Given Below, to GET and SET Files in list.

AudioModel.class

public class AudioModel {

    String aPath;
    String aName;
    String aAlbum;
    String aArtist;

    public String getaPath() {
        return aPath;
    }

    public void setaPath(String aPath) {
        this.aPath = aPath;
    }

    public String getaName() {
        return aName;
    }

    public void setaName(String aName) {
        this.aName = aName;
    }

    public String getaAlbum() {
        return aAlbum;
    }

    public void setaAlbum(String aAlbum) {
        this.aAlbum = aAlbum;
    }

    public String getaArtist() {
        return aArtist;
    }

    public void setaArtist(String aArtist) {
        this.aArtist = aArtist;
    }
}

Now We have our Model Class, use the below code to Read the all MP3 files from your Folder or device.

This will return list of all MP3 Files with Music NAME, PATH, ARTIST, ALBUM. if you want more details, please refer the documentation for Media.Store.Audio

public List getAllAudioFromDevice(final Context context) {

        final List tempAudioList = new ArrayList<>();

        Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
        String[] projection = {MediaStore.Audio.AudioColumns.DATA, MediaStore.Audio.AudioColumns.ALBUM, MediaStore.Audio.ArtistColumns.ARTIST,};
        Cursor c = context.getContentResolver().query(uri, projection, MediaStore.Audio.Media.DATA + " like ? ", new String[]{"%yourFolderName%"}, null);

        if (c != null) {
            while (c.moveToNext()) {

                AudioModel audioModel = new AudioModel();
                String path = c.getString(0);
                String album = c.getString(1);
                String artist = c.getString(2);

                String name = path.substring(path.lastIndexOf("/") + 1);

                audioModel.setaName(name);
                audioModel.setaAlbum(album);
                audioModel.setaArtist(artist);
                audioModel.setaPath(path);

                Log.e("Name :" + name, " Album :" + album);
                Log.e("Path :" + path, " Artist :" + artist);

                tempAudioList.add(audioModel);
            }
            c.close();
        }

        return tempAudioList;
    }

To read the files of a specific folder, use this query (write the target folder name in the query)

Cursor c = context.getContentResolver().query(uri,
                                          projection, 
                                          MediaStore.Audio.Media.DATA + " like ? ", 
                                          new String[]{"%yourFolderName%"}, // yourFolderName 
                                          null);

If you want all the files on the device, use this query:

Cursor c = context.getContentResolver().query(uri,
                                          projection, 
                                          null, 
                                          null, 
                                          null);

Don't forget to add the storage permission.
