Strange exception encountered in android studio

Hi, everyone, I am a monkey who loves to eat bananas. When I was watching the project today, the studio strikes a problem that I haven’t encountered before. Record it

注: 某些输入文件使用或覆盖了已过时的 API。
注: 有关详细信息, 请使用 -Xlint:deprecation 重新编译。
注: 某些输入文件使用了未经检查或不安全的操作。
注: 有关详细信息, 请使用 -Xlint:unchecked 重新编译。
注: 某些消息已经过简化; 请使用 -Xdiags:verbose 重新编译以获得完整输出

I believe that many people have encountered this problem, but some compilation succeeded, a little failed, I am the latter.
Now write about my solution ideas:

First of all, there was no problem with my project before, and now there is an exception. According to the information, it can be believed that it is a configuration problem or a cache problem.
./gradew clean ## invalid
Invalidate cache / restart ## invalid

Then, changing the api, changing the gradle version did not solve
Because my studio version is 4.1, I guess it’s a new version of Yaomozi. After searching, I found it. It’s the cause of androidx. Because the new version does not support support, I need to change to androidx. Therefore, androidx must be disabled.
Disable the two gradle.properties places: see the picture,

modify these two places, it is resolved

Because of the lack of in-depth experience of android studio, I deliberately wrote a record of android studio, and then write new discoveries later.
