Android在不使用listFiles（）方法的情况下列出目录中的所有文件

Question

I am working on a sort of android applications analyzer, by inspecting apps' smali code. In particular I need to know whenever an app tries to get the list of files included in a certain parent directory, so I am currently tracking the following method call (and its overloads):

File[] children = someFolder.listFiles();

What I would like to know is if there is any other method that leads to the same result that I should add to my "tracked" methods, or if the above-mentioned method is the only way to list a folder's content?

Depending on the kernel/ROM a user could run a command in the likes of ls /your/watched/path and just get the output of that command.

If the phone is rooted they most certainly can do this (usually a rooted phone will have busybox). On a non-rooted device this may or may not be possible due to file restrictions and such.
