android - 运行 Android 应用程序时出现 ClassNotFoundException

Question

我正在尝试运行 Spydroid 应用程序 from 。但当它在我的 Nexus 4 上运行时，就遇到了“不幸的是 Spydroid 已停止”。

我使用 egit 将代码副本抓取到 Eclipse 中的新项目中。此时，它抛出了几个错误，告诉我右键单击该项目并选择 Android Tools --> Fix Project Properties。我按照它说的做了，然后点击运行，它将它上传到 Nexus 4，安装它，当它尝试运行时，我就崩溃了。

我在结帐/设置过程中做错了什么吗？ 我在项目的 google code page 上发布了类似的帖子
