Does anyone know if it's possibly to write a lint check that just warns if there's a specific import being used?

[Brandon Trautmann]

Absolutely

[Brandon Trautmann]

On our team we do this -- and add quick fixes to change the import to a desired one (if it applies to your use case)

Nice! I've only written ResourceXmlDetector so I'm trying to figure out what to extend for a java/kotlin file.

[Brandon Trautmann]

SourceCodeScanner IIRC

[Brandon Trautmann]

And Detector as well

[Colton Idle]

Hm. Doesn't seem to be autofilling. I will try to look up more docs and come back if I can't happen to figure it out. Thank you @Brandon Trautmann

[Colton Idle]

@Brandon Trautmann you sure it's not just

Detector(), UastScanner

as in class SampleCodeDetector : Detector(), UastScanner {

Found a better repo with more lint checks. I think I got it. Thank you

There are a couple of examples of custom lint checks and their unit tests which you may find useful https://github.com/jshvarts/CustomLintRule
