i new android app development , while reading google's android documentation came across android sandbox. explanation term not given there tried searching internet couldn't find satisfying. know related security provided linux kernel in android. can please explain me sandbox , how works seems quite important topic .
android applications run on vm (virtual machine), , isolated 1 due permissions android gives each app. each application on android separate user, , have own space on "disk". means applications cannot access each other's space, cannot uninstall or mess each others data.
only 1 user has access os , applications, it's root. when people "root" phone, root permissions, , can mess every application including system services , libraries. that's off topic
