Android networkinfo always returns true, even if the Internet is unavailable

This code always returns true. This is called up when the "Login" button is clicked. At first I tried to connect to Wi-Fi (on the emulator). It came back and then I turned off Wi-Fi and then tried. it returns true anyway.

public static boolean isNetworkAvailable( Context context) {

    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo networkInfo = cm.getActiveNetworkInfo();
            // if no network is available networkInfo will be null
            // otherwise check if we are connected
            if (networkInfo != null && networkInfo.isConnected()) {
                 State network = networkInfo.getState();
                 Log.d("here", "true");
                 return (network == NetworkInfo.State.CONNECTED || network == NetworkInfo.State.CONNECTING);

            }
            Log.d("here1", "false");
            return false;
}
