Answer 1

1.)u can check it as

URL url = new URL("YOUR urlString");
HttpURLConnection conn= (HttpURLConnection) url.openConnection();
.
.
int responseCode = conn.getResponseCode();
//if responseCode = 200 - THEn CONN is connected

OR

2.) u can do somethin like dis

public static boolean isNetworkAvailable(Activity activity) {
        ConnectivityManager connectivity = (ConnectivityManager) activity
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        if (connectivity == null) {
            return false;
        } else {
            NetworkInfo[] info = connectivity.getAllNetworkInfo();
            if (info != null) {
                for (int i = 0; i < info.length; i++) {
                    if (info[i].getState() == NetworkInfo.State.CONNECTED) {
                        return true;  //<--  --  -- Connected
                    }
                }
            }
        }
        return false;  //<--  --  -- NOT Connected
    }

Try this.

private boolean haveNetworkConnection(Context context)
    {
        boolean haveConnectedWifi = false;
        boolean haveConnectedMobile = false;

        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo[] netInfo = cm.getAllNetworkInfo();
        for (NetworkInfo ni : netInfo)
        {
            if (ni.getTypeName().equalsIgnoreCase("WIFI"))
            {
                if (ni.isConnected())
                {
                    haveConnectedWifi = true;
                    Log.v("WIFI CONNECTION ", "AVAILABLE");
                } else
                {
                    Log.v("WIFI CONNECTION ", "NOT AVAILABLE");
                }
            }
            if (ni.getTypeName().equalsIgnoreCase("MOBILE"))
            {
                if (ni.isConnected())
                {
                    haveConnectedMobile = true;
                    Log.v("MOBILE INTERNET CONNECTION ", "AVAILABLE");
                } else
                {
                    Log.v("MOBILE INTERNET CONNECTION ", "NOT AVAILABLE");
                }
            }
        }
        return haveConnectedWifi || haveConnectedMobile;
    }

Hope it will help.
