获取Android中文件的权限（根）

问题描述

经过一番摆弄根设备，我被困上的文件。比方说，我们在这我想读我的应用程序/写的根文件夹某处的一个文件。我迄今发现的唯一方法是改变像文件权限

After some play around with rooted devices, I got stuck on the files. Let's say we have a file somewhere in the root folder which I want to read/write from my application. The only way I found so far is changing the file permission like

String [] cmd = { "su", "-c", "chmod", "777", path};
Process process = new ProcessBuilder(cmd).start();
process.waitFor();

这工作正常，问题是，我想我与它完成后即可返回原始文件的权限。

This works fine, the problem is that I want to return back the original file permissions after I'm done with it.

任何人可以帮助我得到一个文件/目录当前的权限？

Can anybody help me with getting a file/directory current permissions?
