First get a reference to the ConnectivityManager and then check the Wifi and 3G status of the device. You'll need the ACCESS_NETWORK_STATE permission to use this service.

    ConnectivityManager connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
    NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    NetworkInfo mMobile = connManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

    if (mWifi.isAvailable() == true) {
        return "Connected to WiFi";
    } else if (mMobile.isAvailable() == true) {
        return "Connected to Mobile Network";
    } else return "No internet Connection"
