Question [Q] What is the built-in scripting language in Android SmartPhone ?

For Android OS, what is the equivalent of MsDOS script for MS Windows?
In other words, what is the built-in scripting language on Android ?

I'm looking for a script language working on any Android (4.x) not rooted smartphone, without any extra apps (Busybox, Ruboto, ...). If possible a script language that I can launch from the pre-installed file manager on the smartphone, like the one in TouchWiz.
I'd like to write a script to:
- copy/duplicate some files to a folder
- zip/archive this entire folder
- send this archive to a FTP server

I want to launch this script on Android SmartPhone (no rooted) of my friends to backup some app's settings
Thanks in advance and regards.
