帮助！我要疯了！我正在为服务器使用 Visual Basic 6.0 Winsock。我能够保持活动连接，甚至从我的 Android 应用程序接收到 VB 应用程序 "VER:Android,LAT:28.111921,LNG:-81.950433,ID:1038263,SND:0,VDO:0"> 我解析数据并将其放入其字段中。

初次连接后，我尝试从 VB 向服务器发送一条简单消息，但我从未收到它。每当我关闭我的 VB.NET 应用程序时，我会注意到我在 LogCat 中收到这个：

11-26 15:38:16.567: I/TcpClient(986): 收到: null

我是 Android 新手，任何帮助将不胜感激。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
