在Android Studio上更改API级别后出现一些错误和崩溃

如何解决在Android Studio上更改API级别后出现一些错误和崩溃

最近，我已经购买了源代码并进行了一些更改并测试了该应用程序，一切正常！除了我实际上并没有一直在应用程序上收到通知，而是稍后会找到解决方案...尝试将我的应用程序上传到Google Play后，它说我必须至少具有API级别29我只有27岁，我去了“项目结构”并按照以下步骤进行了更改，当我在手机上测试该应用程序时，它会正常打开，但是一旦我单击“菜单”按钮，它就会崩溃！我已经搜索了很多有关在logcat上发现的错误的信息，但对我没有任何帮助。希望你能帮助我。

Logcat上的错误：
