更新gradle文件的依存关系后，我的应用程序出现错误。 当我尝试设置我的“编辑文本”
android:inputType="number"
并尝试输入一些数字，我的应用程序崩溃了。

这是例外。
我认为该错误是由于KeyEventCompat导致的，该事件现在已弃用。但是我找不到合适的解决方案。 任何帮助将不胜感激
这是我的编辑文字

android:background="@drawable/register_edittext_background"
android:inputType="number"

清理构建的缓存并重新构建项目，有时在库上进行一些重大更改时，这会发生在我身上。
如果这不能帮助尝试使缓存无效并重新启动，也许共享更多代码可以帮助发现问题，有了这些信息，这些是我唯一想到的事情。
