No connectivity change with VPN?

Question

Is there a way to get notified when a VPN is connected or disconnected? Because of what I see, the ConnectivityManager does not broadcast any intent about that.

I also tried (unsuccessfully) to register to the hidden ACTION_VPN_CONNECTIVITY broadcast (as seen in android.net.vpn.VpnManager.java source code):

    context.registerReceiver(new BroadcastReceiver()
        {
            public void onReceive(Context context, Intent intent)
            {
                android.util.Log.d("MyApp", "Received VPN broadcast.");
            }
        }, new IntentFilter("vpn.connectivity")); // VpnManager.ACTION_VPN_CONNECTIVITY

So is there a way to detect if a VPN is connected, beside polling the networks interfaces periodically to detect the creation of a new network interface (usually ppp0)?

Best regards, David

sgs2 and emulator worked with:

    getApplicationContext().registerReceiver(new BroadcastReceiver()
    {
        public void onReceive(Context context, Intent intent)
        {
            logger.Log("VPN broadcast "+context.toString()+": ["+intent.toString()+"]");
        }
    }, new IntentFilter("vpn.connectivity"));
