For Android Wi-Fi, is it possible to monitor in / out (e.g. up / down) data transfer information?

Question

I want to re-present the data transfer arrows for Wi-Fi (as seen in the Quick Settings panel) in my app. I have been looking at the source code for Quick Settings and have been roadblocked by a couple of non-public APIs (AsyncChannel & WiFiManager.getWifiServiceMessenger) - does anyone know if there is any conceivable way around this?

For example, NetworkController...

    // wifi
    mWifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    Handler handler = new WifiHandler();
    mWifiChannel = new AsyncChannel(); //Private
    Messenger wifiMessenger = mWifiManager.getWifiServiceMessenger(); // Private
    if (wifiMessenger != null) {
        mWifiChannel.connect(mContext, handler, wifiMessenger);
    }

...is handled in...

// ===== Wifi ===================================================================
class WifiHandler extends Handler {
    @Override
    public void handleMessage(Message msg) {
        switch (msg.what) {
            ...
            case WifiManager.DATA_ACTIVITY_NOTIFICATION:
                if (msg.arg1 != mWifiActivity) {
                    mWifiActivity = msg.arg1;
                    refreshViews();
                }
                break;
            ...
        }
    }
}

...where mWifiConnectivity is communicated to the Quick Setting panel.

I am thinking this is not possible, but thanks for your consideration and confirmation of this hunch :-\
