在soap URL中尝试在SQL服务器中插入数据时，我在互联网没有连接时做了一个干杯，如果它连接了它就插入数据和＆＃34;注册数据＆＃34;将显示toast消息。
如果存在，它会检查WiFi连接并且成功注册＆＃34; reg成功＆＃34; 如果没有WiFi，它会同时发送消息（包括reg消息。）。
但在我的情况下，当互联网关闭时，已经显示了两个烘烤。

In soap URL tried to insert data's in SQL server, i did a toast when internet is not connected and if its connected it insert the data and "Register data" toast message will be displayed.
It's checking WiFi connection if exists it toasts the message"reg successfully"
and if not have a WiFi it toasts both message(including reg message also.).
But in my case the both toasted has been displayed when internet is off.
\\ But in my case the both toasted has been displayed when internet is off.

根据你的代码，将显示两个祝酒词。我猜你错过了最后一个块。我猜这个代码应该在其他区块内。 :-) 喜欢这个
