我是android APP的新手。我下载 facebook sdk for android ( https://developers.facebook.com/android/ )。除了在模拟器中运行外,一切都很好。 SDK中所有samples都不能正常运行,报“不幸的是,XXX已停止”的错误。有人能遇到类似的问题吗?谢谢。这是 LogCat 中的日志:

您需要将外部 .jar 文件移动到“libs”文件夹,否则它们的类将不会包含在创建的 .dex 文件中。

此问题从 ADT 17 开始发生。要解决此问题,请确保 ADT 正确、构建路径配置正确且外部 jar 文件位于 libs 文件夹中。
