根据this问题，我的应用程序正在抛出看似随机的错误。每当我添加重大更改（新资源，新代码，函数调用）等时，工作正常的代码就会崩溃。活动根本不会启动。 logcat输出告诉我XML文件有错误。不幸的是，我没有触及该文件。仔细观察它，它也告诉我一些动画XML文件中没有的颜色资源。 logcat输出如下：代码：

最后是定义时钟颜色的资源：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="clockTextColor">#FFFFFF</color>
</resources>

感谢CommonsWare。不知何故，XML变得不同步。也许是因为我不使用Eclipse。无论如何，解决方法是删除bin目录，重新编译和安装。
