Lint checks to ensure Java code interops well with Kotlin (available since Canary 10)
To make sure your Java code interoperates well with your Kotlin code, new Lint checks enforce the best practices
described in the Kotlin Interop Guide. This includes checking for the presence of Nullability annotations, use of
Kotlin hard keywords, placing lambda parameters last, and others.
To enable these checks, go to File > Preferences > Editor > Inspections and check the rules that you want to
enable under Kotlin Interoperability:
Once you have checked the rules you would like to enable, the new checks will run when you run your
code inspections (Analyze > Inspect Code…)
To enable these checks from the command-line builds, add the following line in your build.gradle file:
android {
lintOptions {
check 'Interoperability'
}
}
