java.lang.RuntimeException:无法实例化活动

很抱歉，我看到过类似的帖子，但它们对我找到的所有帖子都没有帮助。当我重新格式化我的笔记本电脑并使用多种工具来恢复代码时，我丢失了我的项目，但这并不是我所拥有的方式。在再次修复之后，我不断遇到这些错误，我对java有点陌生，所以请解释一下

试试：

删除

导入com.sundaysalmody.R从您的
SundayPsalmody
活动中的导入列表

检查是否在

Manifest.xml

文件中正确声明了所有

活动

清理并构建您的项目

运行应用程序

---

请清理这个项目。运行新的构建。删除

import com.sundaypsalmdoy.R从导入列表中，检查是否在清单文件中正确声明了所有活动文件然后尝试清理并构建项目。然后尝试运行应用程序..当我删除import com.sundaypsalmdoy.R时；它抱怨所有的R.id和R.layout，这就是我感到困惑的地方。我知道它不应该在那里。当你清理你的项目并再次构建时，R.java会自动生成。我一直删除com.sundaypsalmody.R，但它会抱怨R.id.[任何控制]。当我重新添加任何控件时，它会再次添加com.sundaypsalmody.R。。。我真的很想继续这个项目，而不是开始一个新的副本，因为我想更新已经上市的应用程序，而不是添加一个新的。问题在于清单中没有正确地声明活动，而不是我需要非常感谢你帮助我回答你的#2！
