Question

我创建了一个android应用程序，在另一个Android应用程序中用作库。我在android应用程序中使用了一些第三方jar作为库。当我在我的Android应用程序中链接这个库并运行它时，我在尝试访问库中的类时遇到验证错误。我可以知道这里阻止的问题是什么？任何帮助非常感谢..

我在这里附加了日志，Parser1是库中的类。当我尝试为Parser1类创建对象时，我在行中收到错误。

Answer 1

在Eclipse中，转到Project properties -> Java Build Path。选择Order and Export标签并检查您的第三方广告。

Answer 2

这可能是因为jar中的某些东西在Java中访问了Android SDK中没有的内容。在LogCat中查找异常，它可能会告诉您缺少的内容。如果您有第三方jar的来源，请尝试将它们直接包含在您的项目中;这将有助于解决问题。

您还需要通过sdk附带的“dx”工具运行您的jar文件。

Answer 3

如果您使用的是ant，那么您应该将所有外部jar添加到以下目录“libs”中，并在新文件中添加以下行：ant.properties： jar.libs.dir =库

Answer 4

如果您在使用ProGuard构建应用发布版本后获得VerifyError，则可能与某些优化问题有关。 Refer to the documentation，主要建议使用-dontoptimize禁用优化。

Answer 5

从/ libs文件夹中删除所有jar文件，然后再次添加它们，然后清理项目并为我修复它。

Answer 6

同样的错误发生在我身上，因为我试图在v.8 API设备上捕获异常SQLDataException，因为相应的类不包含在v.8 API中（错误没有发生在v.14设备中，其中该课程包括在内）。实际上，SQLDataException.class不仅存在于v.8 API的android.jar中，而是包含在v.14 API中。所以我用异常SQLException（其SQLDataException是一个子类）替换异常SQLDataException，我的应用程序现在可以在两个API的设备上正常运行。

得到“引起：java.lang.VerifyError：”
