我的应用程序持续崩溃，我无法查看问题所在

Question

这是我的代码。请检查。当我执行它时，应用程序崩溃了。因此，应用程序之前还不错，但是我在表单中添加了验证，从那时起，应用程序运行时便崩溃了。我已经使用https://www.simplifiedcoding.net/android-form-validation-tutorial/添加了awsomeform，因此也对strings.xml文件进行了一些更改。请检查一次。以前很好，我可以很轻松地访问文件。

这是我尝试运行该应用程序并安装，启动然后崩溃时在Android Studio上遇到的错误。

这是我的主要活动代码。我认为工具部分正在发生某些情况，并且该代码（即import.com.google.common.collect.range）也未使用
