AndroidStudio disable "Expected resource of type string"

I've just tried to generate signed apk for one of my projects (I already did this before), but (maybe since updating Android Studio) I'm getting

Error:Error: Expected resource of type string [ResourceType]

This is because I'm using Butterknife's @BindString, that is generated into something like that

target.settings = res.getString(2131230792);

How can I make studio not detect this as error? I've tried searching in settings, but without success.

Solution

This is reported on the GitHub project. It will be fixed in the next version of ButterKnife.

The workaround is indicated there, and is to add a lint.xml file on the app module with the following content to ignore that errors on *$$ViewBinder classes (the ones that ButterKnife generates):

<issue id="ResourceType">
    <!-- Remove this when this is fixed: https://github.com/JakeWharton/butterknife/issues/338 -->
    <ignore path="**/*$$ViewBinder.java" />
</issue>
