Android编程获取root权限后无法访问/root和/data文件夹解决办法

Android编程获取root权限后无法访问/root和/data文件夹
文件管理器获取root权限后，注意获取成功！到真机上上测试也是提示获取权限成功，可是问题来了为啥这还访问不了/root等文件夹呢
权限获取代码：

Java code



/**
     * 应用程序运行命令获取 Root权限，设备必须已破解(获得ROOT权限)
     * 
     * @param command
     *            命令：String apkRoot="chmod 777 "+getPackageCodePath();//RootCommand(apkRoot);
     * @return 应用程序是/否获取Root权限
     */
    public static boolean RootCommand(String command) {
        Process process = null;
        DataOutputStream os = null;
        try {
            process = Runtime.getRuntime().exec("su");
            os = new DataOutputStream(process.getOutputStream());
            os.writeBytes(command + "\n");
            os.writeBytes("exit\n");
            os.flush();
            process.waitFor();
        } catch (Exception e) {
            return false;
        } finally {
            try {
                if (os != null) {
                    os.close();
                }
                process.destroy();
            } catch (Exception e) {
            }
        }
        return true;
    }

------解决方案--------------------
Process process = null;
DataOutputStream os = null;
try {String command = "chmod 777 " + "data";

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

} finally {
try {
if (os != null) {
os.close();
}
process.destroy();
} catch (Exception e) {
}
}
这样可以访问data文件夹
------解决方案--------------------

String[] command={"su","-c","/data"}
Process=Runtime.getRuntime().exec(command);
process.waitfor();
os = new DataOutputStream(process.getOutputStream());

不知道这样行不行了~
