Re: [android-developers] Runtime.exec("su") issue.

yes ， If u exce "su" ,u must be get root permission first

2012/1/18 Putti Me <puttime@gmail.com>

I try to execute the following code:

 

try
{
 Process process = Runtime.getRuntime().exec("su");
    // blah blah
}
catch (Exception e)
{
 res += "ERROR " + e.getMessage() + "\n";
}

And I get the following exception::

Error running exec(). Command: [su] Working Directory: null Environment: null

 

Any reason why?

Do I need "root" access on my device?
