Question

我正在使用LibGDX构建游戏，之前我已经能够启动桌面和Android项目，但是我最近集成了一个额外的外部库，现在Android项目无法启动（但是桌面项目仍然启动而没有错误。）

LogCat输出为：

据我所知，我正确地导入了库，因为它出现在我项目的Referenced Libraries文件夹中，但也许我错过了什么？

在有帮助的情况下使用Eclipse。

以下是与其他人讨论您所遇到的错误消息的论坛：http://badlogicgames.com/forum/viewtopic.php?f=11&t=13710

一般情况下，如果您在论坛上发帖而不是StackOverflow，您可能会获得更多相关建议。（虽然没有理由不向两者发帖）

例如，我是一名Android开发人员，我可以想到在导入库项目时可能会出错的一些事情，但似乎这个lib有一个安装库（gdx-setup.jar）对你不利的东西，我无法提供建议。

Answer 2

原来问题出在构建路径配置中。这些库已添加到构建路径中，并列在构建路径对话框的“库”选项卡中，但是在“订购和导出”选项卡中未检查库。

我检查了它们，现在它可以工作了。
