Create Thumbnail for folder in android

Question

Can somebody please tell me how to create thumbnail just like Hike and Battery Doctor does? I have created new folder in internal storage with

File root = Environment.getExternalStorageDirectory();
                File Dir = new File(root.getAbsolutePath() + "/myfolder");
                if (!Dir.exists()) {
                    Dir.mkdir();

                }

File Utility does not have setBackgroundDrawable function as discussed in other posts. I tried copying .bmp image in created folder. Still such thumbnail does not show up.

EDIT: All posts here in stackoverflow discusses about creating thumbail for images as in here and for videos as in here. However I do not see any post regarding setting thumbnail for folder.

Thanks in advance!!!

It's not quite clear to me what you are trying to achieve. Could you describe your problem a bit more ? — Jonas Czech, Jan 04 '16 at 16:49

Are you using ES File Explore to checking that? Because I found this post Create folder and make ES File Explorer add icon of my app Sorry because I don't have permission to add comment.
