我正在尝试将外部 JAR 添加到我的项目中，但收到此错误：

我了解我添加的 jar 和库项目（Open-Feint 库）存在冲突。

我的问题是我是否可以做些什么来解决这个问题？

我对 OpenFeint 库有同样的问题，我想通了。

如果您还包括 GameFeed 项目

项目 > 属性 > Android > 库

部分，您可能会包含两次 OpenFeint API 源代码，一次在 OpenFeint 库中，一次在 GameFeed 项目中作为依赖库。

我不得不从 GameFeed 项目中删除 OpenFeint API 源链接，然后一切正常。

底线是不知何故，您的项目中两次构建了一些源代码。

一个不太好的解决方案是检查双类文件是否是相同的确切版本，如果是，则从其中一个 jar 中删除它们......这是一种解决方法，但不是一个非常安全的解决方案......只做如果你必须。
