# Android Expired Strings

This linter checks that Android string resources marked for removal
(`moz:removedIn`) are not referenced anywhere in the codebase.

When a developer marks a string with `moz:removedIn`, it means the string is
no longer used and its definition is only kept so it can safely ride the release
trains. Any remaining references (`R.string.<name>` or `@string/<name>`)
indicate an incomplete removal.

## Run Locally

This mozlint linter can be run using mach:

```{eval-rst}
.. parsed-literal::

    $ mach lint --linter android-expired-strings <file paths>
```

## Configuration

This linter is enabled by default, and will run if you make changes to
`.kt`, `.java`, or `.xml` files under `mobile/android`.
