[英]Android App is crashing in Super.onCreate(savedInstanceState) at the very begining
我的应用程序在一开始就崩溃了，在protected void onCreate(Bundle savedInstanceState)方法的第一行代码中，该行是super.onCreate(savedInstanceState); ，当我进行调试时，它已将我指向一个充满错误的文件（ ActivityThread.java ）。 有很多导入语句不起作用，还有很多未解析的符号。 我从未遇到过此文件的问题，我想知道我是否已更改了manifest或build.graddle中的重要内容，因为我确实陷在android studio中，并且正在关注google教程，但我也听说它们已被弃用，所以我也遵循此代码 。 此外，我今天已经更新了android studio软件，而打开时我的项目不在那儿，所以我不得不再次导入它，不知道这是否可能是问题的原因。 我没有发布logcat，因为它几乎是无限的，但如有必要，我将进行编辑。 任何帮助，将不胜感激。
这是（ ActivityThread.java ）的屏幕截图
