              ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

              NetworkInfo netInfo = cm.getActiveNetworkInfo();

              if (netInfo != null && netInfo.isConnectedOrConnecting()

                           && cm.getActiveNetworkInfo().isAvailable()

                           && cm.getActiveNetworkInfo().isConnected()) {

there another method you want to use 

       public static booleanhaveNetworkConnection(final Context context) {

              boolean haveConnectedWifi = false;

              boolean haveConnectedMobile = false;

              final ConnectivityManager cm = (ConnectivityManager) context

                           .getSystemService(Context.CONNECTIVITY_SERVICE);

              if (cm != null) {

                     final NetworkInfo[] netInfo = cm.getAllNetworkInfo();

                     for (final NetworkInfo netInfoCheck : netInfo) {

                           if(netInfoCheck.getTypeName().equalsIgnoreCase("WIFI")) {

                                  if(netInfoCheck.isConnected()) {

                                         haveConnectedWifi = true;

                                  }

                           }

                           if (netInfoCheck.getTypeName().equalsIgnoreCase("MOBILE")) {

                                  if(netInfoCheck.isConnected()) {

                                         haveConnectedMobile = true;

                                  }

                           }

                     }

              }

              return haveConnectedWifi || haveConnectedMobile;
