how to determine, if an internet connection is currently available and active on an android device?

i have this android application that requires to load data from a remote server via the internet. this update-functionaliy obviously requires the device to not only be connected to some kind of network, but also to the internet.

so: is want to schedule the update-service to some date and when it starts, it should determine whether it actually CAN reach the target server or not. therefore, a simple "is the device connected to wifi?" does not suffice, as the device may be connected to a wireless network that does not offer internet access. something like a PING is required...

whats the easiest / best way to determine, if there is an internet connection is available i.e. server is reachable?

ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
            if(connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED || 
                    connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED) {
                //we are connected to the internet
                connected = true;
            }
            else
                connected = false;

Just try to connect to your server, and timeout if you haven't started download progress in an acceptable period of time.
