if (connectivity == null) {

return -1;

} else {

NetworkInfo[] info = connectivity.getAllNetworkInfo();

if (info != null) {

for (int i = 0; i < info.length; i++) {

if (info[i].getState() == NetworkInfo.State.CONNECTED) {

NetworkInfo netWorkInfo = info[i];

if (netWorkInfo.getType() == ConnectivityManager.TYPE_WIFI) {

return 2;

} else if (netWorkInfo.getType() == ConnectivityManager.TYPE_MOBILE) {

return 1;
