Assuming the device is rooted and your app has been granted superuser permissions, you can use the following method to run commands as root:

public static void runAsRoot(String[] cmds){
        Process p;
        try {
            p = Runtime.getRuntime().exec("su");
            DataOutputStream os = new DataOutputStream(p.getOutputStream());  
            BufferedReader bf = new BufferedReader(new InputStreamReader(p.getInputStream()));
            for (String tmpCmd : cmds) {
                os.writeBytes(tmpCmd+"
");
                String test;
                while((test = bf.readLine()) != null)
                {
                    Log.i(TAG, test);
                }
            }

            //os.writeBytes("exit
");  
            os.flush();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Just pass it a list of commands in a String array.
