問題：連線加密的熱點 就可以連線，連線不加密的熱點不能連線。addNetwork這個操作總是返回-1 

程式碼如下：這是connect

public static boolean Connect(String SSID, String Password, int Type) {         
        WifiConfiguration wifiConfig = createWifiInfo(SSID, Password, Type);        
        if (wifiConfig == null) {
        Log.v(TAG,"wifiConfig == null");
            return false;
        }
        int netID = settingWifiAdmin.wifiManager.addNetwork(wifiConfig);
        Log.v(TAG,"netID = "+netID);//連不加密AP總是返回-1  
        boolean bRet = settingWifiAdmin.wifiManager.enableNetwork(netID, true);
        return bRet;
    }

解決辦法：

  if(Type == WifiCipherType.WIFICIPHER_NOPASS)
      {
      config.hiddenSSID = true;  
//        config.wepKeys[0] = "";
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
//        config.wepTxKeyIndex = 0;
      }
