如何在Android 6（M）上以编程方式更改WiFi配置？

Question

在this链接中，有一种方法可以在Android 5（L）中执行此操作。有这样的方法：

public static void setDNS(InetAddress dns1, InetAddress dns2, WifiConfiguration wifiConf)
    throws SecurityException, IllegalArgumentException, NoSuchMethodException, InvocationTargetException,
    NoSuchFieldException, IllegalAccessException {

    Object linkProperties = null;
    ArrayList<InetAddress> mDnses;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        staticIpConf = wifiConf.getClass().getMethod("getStaticIpConfiguration").invoke(wifiConf);
        mDnses = (ArrayList<InetAddress>) getDeclaredField(staticIpConf, "dnsServers");
    }
    else {
        linkProperties = getField(wifiConf, "linkProperties");
        mDnses = (ArrayList<InetAddress>) getDeclaredField(linkProperties, "mDnses");
    }

    mDnses.clear();
    mDnses.add(dns1);
    mDnses.add(dns2);
}

但是在android M中，wifi静态ip配置中没有字段“dnsServers”。这是否意味着无法在6.0中更改wifi设置？
