HELP！我要疯了！我正在为服务器使用Visual Basic 6.0 Winsock。我能够保持活跃的连接，我甚至从我的Android应用程序收到VB应用程序“VER：Android，LAT：28.111921，LNG：-81.950433，ID：1038263，SND：0，VDO：0”＆gt;我解析并将数据放在他们的字段中。
在我的初始连接后，我尝试从VB向服务器发送一条简单的消息，但我从未收到过。每当我关闭我的VB.NET应用程序时，我会注意到我在LogCat中接收到这一点：
11-26 15：38：16.567：I / TcpClient（986）：收到：null
我是Android新手，任何帮助都会受到高度赞赏。我需要帮助尝试通过我的客户端（Android）和服务器（VB）来回接收和发送消息
