Which API do you use to inspect the caller of an annotated function?

10/14/2021, 7:55 PMif you're not generating code but just checking it, you could consider Android Lint (which can be applied to non-Android projects, http://googlesamples.github.io/android-custom-lint-rules/api-guide/example.md.html#:~:text=com.android.lint )
