Cucumber error – invalid byte sequence in UTF-8 (ArgumentError)

Ever get an invalid byte sequence in UTF-8 (ArgumentError) when trying to run your calabash-android project?
Here’s a thing to check – have you got 2 apks in your apk folder / prebuilt folder?
That’s usually the cause.

 

Hope that helps someone out there save 30 minutes trying to work out why your test isn’t running.
