致命异常：main java.lang.VerifyError:net.sourceforge.jtds.jdbc.TdsCore

在我的Android项目中，我使用jtds.jdbc连接SQL Server数据库。在尝试连接时，我写入了错误的连接字符串，该字符串引发了一个错误：“网络错误IOException:连接超时”

这证明了JTDS包含在我的项目中并在工作。但是，当我编写正确的连接字符串时，出现了以下错误：

Myjtds-1.3.1.jar位于libs文件夹和Android私有库中，并按顺序进行检查和导出

GSSManager是一个来自Java的类。但是我确实在构建中包含了jre7

我确实试过：

• 构建路径的所有技巧
• 更改java编译级别

有什么建议吗

编辑：sendGssToken（）方法可以在org.ietf.jgss.GSSManager和net.sourceforge.jrds.jdbc.TdsCore类中找到。我刚刚使用了一个Earler jar，它工作正常。

遇到了同样的问题，跳回使用jtds-1.3.0.jar并解决了问题。+1
