VFY:无法找到签名中引用的类

Question

我有一个简单的Android应用程序,它在其构建路径上使用modbus库("jamod").它在运行时立即崩溃.我在这个问题上遇到了同样的问题:得到"引起:java.lang.VerifyError:"

但我无法解决问题.我的应用程序之前工作正常,现在无论我做什么它似乎都不起作用.

下面是logcat输出.提前致谢.

Answer 1

仔细检查你要做的一件事就是在Build path窗口的"Order and Export"选项卡中勾选jar文件的复选框.这将包括构建APK的库.

Answer 2

您是否将 jamod jar 文件放在 Eclipse 的“libs”目录中？如果不是，即使它在编译期间位于路径上，它也不会被捆绑到您的应用程序中。这是一个相当新的变化。
