Android判断是否为wifi环境

/**  * make true current connect service is wifi  * @param mContext  * @return  */  private static boolean isWifi(Context mContext) {      ConnectivityManager connectivityManager = (ConnectivityManager) mContext              .getSystemService(Context.CONNECTIVITY_SERVICE);      NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();      if (activeNetInfo != null              && activeNetInfo.getType() == ConnectivityManager.TYPE_WIFI) {          return true;      }      return false;  }
