Why does the IsConnected Android function always return true, even when I turned Wi-Fi off?

Question

I tried to check Internet Connectivity in my App to handle if there is no internet with this code. It always returns true with Wi-Fi type.

ConnectivityManager connMgr = (ConnectivityManager)
                getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();

        if (networkInfo != null && networkInfo.isConnected()) {
            System.out.println(  networkInfo.getTypeName());
            Loading_News();
        }
