Background: After a long time, the project was opened and packaged again and an error was reported:

I began to suspect that the studio version was updated, and the gradle version in the project was too low.
Modify the project gradle version to the version in other normal projects
Repackage after modification:
Still reporting an error, but solved one.
After that, click build.gradle(:app): I found an error message in the upper right corner
click open
Modify the targetSdk version, note that the targetSdk version under each module must be modified
Then the error is still reported, after the clean project, the build files that cannot be deleted are manually deleted in the folder, and then the rebuild project is packaged successfully.
The above are the solution process notes I recorded when a bug occurred.
