Buggy source:
static public NetworkStatus checkConnectivity(Context context){
  RCLogger.d(TAG,"String_Node_Str");
  ConnectivityManager connectivityManager=(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
  NetworkInfo activeNetwork=connectivityManager.getActiveNetworkInfo();
  if (activeNetwork != null) {
    if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI && activeNetwork.isConnected()) {
      RCLogger.w(TAG,"String_Node_Str");
      return NetworkStatus.NetworkStatusWiFi;
    }
    if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE && activeNetwork.isConnected()) {
      RCLogger.w(TAG,"String_Node_Str");
      return NetworkStatus.NetworkStatusCellular;
    }
    if (activeNetwork.getType() == ConnectivityManager.TYPE_ETHERNET && activeNetwork.isConnected()) {
      RCLogger.w(TAG,"String_Node_Str");
      return NetworkStatus.NetworkStatusEthernet;
    }
  }
  RCLogger.w(TAG,"String_Node_Str");
  return NetworkStatus.NetworkStatusNone;
}
