运行Android应用程序时发生ClassNotFoundException

Question

我试图运行Spydroid应用程序from。但遇到一个“不幸的Spydroid已停止”，只要它运行在我的Nexus 4上。

我用egit在eclipse中获取一个新项目的代码副本。在那时，它抛出了一些错误，告诉我右键单击该项目并选择Android Tools - > Fix Project Properties。我按照说的做了，然后运行，将其上传到Nexus 4，安装它，当它试图运行时，我得到了崩溃。

我在结帐/设置过程中做错了什么？ 我张贴了类似的帖子，以项目的google code page

logcat的：
