do way

replace these 2 lines

lessontemplatearraylist.setvideo(customfieldsobject.getstring("wpcf-video").replace("\\", "")); lessontemplatearraylist.seticonimage(customfieldsobject.getstring("wpcf-icon").replace("\\", ""));

with

lessontemplatearraylist.setvideo(customfieldsobject.getjsonarray("wpcf-video").getstring(0));     lessontemplatearraylist.seticonimage(customfieldsobject.getjsonarray("wpcf-icon").getstring(0));
