I want to retrieve files from my android device and list them in a List View or Recycler View. I need to do this using the files extension so that I may also retrieve custom-made files with their own file extension, eg: “.xyz”. This is what I’ve done so far

public static ArrayList<MyFiles>getAllFiles(Context context){
        ArrayList<MyFiles>tempList = new ArrayList<>();
        Uri uri = MediaStore.Files.getContentUri("external");
        Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
        if (cursor!=null && cursor.moveToFirst()){
            while (cursor.moveToNext()){
                String path = cursor.getString(cursor.getColumnIndex(MediaStore.Files.FileColumns.DATA));
                String title = cursor.getString(cursor.getColumnIndex(MediaStore.Files.FileColumns.DISPLAY_NAME));
                String ext = title.substring(title.lastIndexOf(".")+1);
                if (ext.equals("mp3")||ext.equals("m4a")||ext.equals("xyz")){
                    // check...
                    Log.e("path: "+path,"Name: "+title);
                    //adding the path and title to my Model Class
                    MyFiles myFiles = new MyFiles(path,title); 
                    tempList.add(myFiles);
                }
            }
        }
        return tempList;
    } 

This method successfully returns a List of files with “.mp3” and “.m4a” extensions but files with the extension “.xyz” are not showing. What am I missing, or is there a better way of doing this?
