How to select music files from a specific folder like "MyMusic" in RecyclerView-CodePudding

This is my code. It is fetching songs from all directories but i want to get only from specific folder. How can i do it

private void readMediaFiles() { ContentResolver contentResolver = context.getContentResolver();

    Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String music  = MediaStore.Audio.Media.IS_MUSIC   " != 0";
    Log.d("this123",music.toString());
    String sort  = MediaStore.Audio.Media.ALBUM   " ASC";
    String[] projection = {MediaStore.Audio.Albums.ALBUM_ID, MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.DATA};
    Cursor cursor = contentResolver.query(uri,projection,music,null,sort);

    if(cursor != null) {
        Msg.log(String.valueOf(cursor.getCount()));
        if(cursor.getCount() > 0) {
            while(cursor.moveToNext()) {
                @SuppressLint("Range") String path = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
                @SuppressLint("Range") String title = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
                @SuppressLint("Range") String albumid = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ID));
                mediaListModel = new MediaListModel(Long.parseLong(albumid),path,title);
                mediaListModelArrayList.add(mediaListModel);
            }
        }`

You can achieve your goal of fetching only songs from a specific folder by using this approach :

String music = MediaStore.Audio.Media.IS_MUSIC   " != 0 AND "  
            MediaStore.Audio.Media.DATA   " LIKE '/mnt/sdcard/Music/SomeArtist/%'";

The /mnt/sdcard/Music/SomeArtist/ is where you want to fetch songs only from there. This limits your managedQuery results to the .../SomeArtist/ dir.

Try this...

 Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
        String paths = Environment.getExternalStorageDirectory().getPath();

        String music = MediaStore.Audio.Media.IS_MUSIC   " !="   0
                  " AND "   MediaStore.Audio.Media.DATA  
                " LIKE '"   paths
                  "/Music/BGM/%'";
        String sort = MediaStore.Audio.Media.ALBUM   " ASC";
        String[] projection = {MediaStore.Audio.Albums.ALBUM_ID, MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.DATA};
        Cursor cursor = contentResolver.query(uri, projection, music, null, sort);
