推荐答案

如果您的手机扎根，你可以通过苏问题作为根命令＆MDASH;提供的苏二进制文件是present并在 PATH ＆MDASH;由于Android是Linux的一个变种。只需通过执行删除命令的Runtime.exec（），和超级用户应采取及时的权限照顾。

If your phone is rooted, you can issue commands as root through su—provided that the su binary is present and in your PATH—since Android is a variant of Linux. Simply execute the delete commands through Runtime.exec(), and Superuser should take care of the permission prompt.

下面是其用法的一个简单的例子，我花了从这个问题：

Here's a simple example of its usage I took from this question:

process = Runtime.getRuntime().exec("su");
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(command + "\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
