Setting up linting/formatting for an Android project
In my experience, I have faced these issues while trying to keep the code style consistent across the team - 1. ktlint and "Reformat Code" in Android Studio produce different outputs. This causes issues as most developers find it easier to use "Reformat Code" in AS but if you have a ktlint check on CI, the checks sometimes fail. 2. Different AS versions produce different `codeStyles.xml` file. Sometimes, on updating AS, it automatically adds new rules to the `codeStyles.xml` file. These rules might not be compatible with ktlint and might only work on specific AS versions.

Three features in Android Studio that maybe you've missed
Not even an Android Studio-specific feature, but rather a feature of the underlying IntelliJ. Just select Code > Analyze code > Silent code cleanup and your entire project will be cleaned up using the default linter (this can be combined awesomely with Ktlint).
