救命！ 我要疯了！ 我使用Visual Basic 6.0 Winsock的服务器。 我能够保持一个有效的连接，我甚至从我的Android应用程序接收到VB应用程序 “VER：安卓，纬度：28.111921，LNG：-81.950433，编号：1038263，SND：0，VDO：0”>我哪解析并把数据在各自的领域。
我最初的连接后，我尝试从VB发送一个简单的信息到服务器，我从来没有收到。 我确实注意到，每当我结束我的VB.NET应用程序我在logcat中收到这样的：
11-26 15：38：16.567：I / TcpClient的（986）：接收到的：空
我是新来的Android任何帮助，将不胜感激。 我需要帮助想收到和发送消息来回通过我的客户端（Android）和服务器（VB）
