Android facebook SDK做错误java.lang.NoClassDefFoundError [英] Android facebook SDK doing error java.lang.NoClassDefFoundError‎

问题描述

我刚刚从 http://github.com/facebook/facebook- android-sdk
我从git解压缩它并打开Eclipse。然后我使用现有的源创建了一个新项目，并选择了facebook目录。所以sdk项目正确地出现（我想）。然后我再次使用现有的源创建了一个新的项目，并选择了简单的例子。
它提出了错误。我进入了属性，选择了Build Path部分，并添加了facebook SDK项目并进行了应用。所有错误消失。
然后我尝试运行示例，但是在第一次调用facebook SDK功能时收到异常！异常是NoClassDefFoundError。它似乎在运行时找不到SDK的类。怎么来的 ？有什么建议么 ？有人成功运行这个例子？任何帮助将不胜感激。

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.
