将我的apk上传到Play商店时，它挂断并显示以下消息。我已经删除了所有SDK，并且在Android Studio中仅安装了28个SDK，在<preference name="android-minSdkVersion" value="28"/>中设置了config.xml，但它仍在继续。我该如何解决？

Your app currently targets API level 27 and must target at least API level 28 to ensure it is built on the latest APIs optimized for security and performance. Change your app's target API level to at least 28. Learn how.
