问题描述

我刚刚下载了Facebook的SDK从<一个href="http://github.com/facebook/facebook-android-sdk">http://github.com/facebook/facebook-android-sdk 我从混帐解压缩，打开Eclipse中。然后，我创建了使用现有源的新项目，并选择了Facebook的目录。所以SDK项目正确想出了（我认为）。然后，我又创建了使用现有源的新项目，并选择简单的例子。 它想出了错误。我去的属性和选择的构建路径部分，并添加了Facebook的SDK项目，applyed。所有的错误消失。 然后我试图运行的实例，但即时通讯上的Facebook SDK函数第一次调用得到一个例外！例外情况是出现NoClassDefFoundError。它似乎在运行时无法找到类的SDK。怎么来的 ？有什么建议么 ？有人却成功地运行这个例子？任何帮助将大大AP preciated。

I have just downloaded the facebook SDK from http://github.com/facebook/facebook-android-sdk I unpack it from git and opened Eclipse. I then created a new project using existing source and selected the facebook directory. So the sdk project came up correctly (i think). Then I created a new project again using existing source and selected the "Simple" example. Its came up with errors. I went in the properties and selected Build Path section and added the facebook SDK project and applyed. All the errors disappear. I then tried to run the Example but im getting an exception on the first call to facebook SDK function ! Exception is NoClassDefFoundError. Its seems that at runtime it cannot find the class of the SDK. How come ? Any suggestions ? Someone did sucessfully run this example ? Any help would be greatly appreciated.
