MediaStore does not work when a folder is created programmatically

Question

I am accessing videosfrom a programmatically created folder using the following code. But it returns the number of cursors 0, what should I do to solve this problem.

I tested it on some devices, this does not work for everyone

 String selection=MediaStore.Video.Media.DATA +" like?";
        String[] selectionArgs=new String[]{"%smartVcall%"};
        videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
                parameters, selection, selectionArgs, MediaStore.Video.Media.DATE_TAKEN + " DESC");

To create a folder, I use the following code

 File moviesDir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/smartVcall");
        if (!moviesDir.exists()) {
            moviesDir.mkdirs();
        }
