android - VFY : unable to find class referenced in signature

Question

我有一个简单的 android 应用程序，它在其构建路径上使用了一个 modbus 库(“jamod”)。它在我运行时立即崩溃。我在这个问题上有基本相同的问题:Getting "Caused by: java.lang.VerifyError:"

但我无法真正解决问题。我的应用程序之前运行良好，现在无论我做什么似乎都不起作用。

下面是 logcat 输出。提前致谢。

要仔细检查您正在做的一件事是在“构建路径”窗口的“订购和导出”选项卡中勾选了 jar 文件的复选框。这会将库包含在构建的 APK 中。
