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,我收到了错误.

Answer 1

在Eclipse,去Project properties -> Java Build Path.选择Order and Export选项卡并检查您的第三方罐子.

Answer 2

这可能是由于 jar 中的某些内容访问了 Android SDK 中未包含的 Java 内容所致。在 LogCat 中查找异常，它可能会告诉您缺少什么。如果您有第 3 方 jar 的源代码，请尝试将它们直接包含到您的项目中；这将有助于确定问题。

您还需要通过sdk附带的“dx”工具来运行您的jar文件。
