这个错误是什么意思？我在运行时遇到这个错误。当我尝试启动时，应用程序崩溃了。我是Android编程新手。

我试图查看代码，但找不到它。我很感激你的帮助。

Answer 1

首先，检查您的源是否在错误日志中提到的位置。
如果是，请检查您是否犯了任何打字错误
如果它仍然不起作用，那么创建一个新项目并重命名缺少的内容会更容易（在我看来）（我已经多次完成这项工作并且它一直有效）当然，请确保你复制了所有的代码

Answer 2

看起来你错过了清单中的Splash活动。

    <activity android:name=".Splash"/>

查看您的清单中是否显示该行，如果不是，则应添加该行。

运行时出错 - 该怎么办？
