Android static library - source files not included

Hi there - I am using the latest version of projucer and the latest version of JUCE to try and build a static android libraray. I’m using the standard Android Static Library template with the addition of a CPP and H file in the Source directory which I have added in in Projucer. When I export the Android Studio project opens up and contains all the JUCE static library things I’d expect - but I can’t find any reference to my CPP source file anywhere. I was expecting to see that somewhere in the heirachy in Android Studio. Is that not how it works? If someone could explain where they would expect my CPP source files to be in AS that would be very helpful.

Thanks, Simon.
