[Interest] Android NFC compile error

[Jason H]

I'm following along with: http://doc.qt.io/qt-5/qtnfc-annotatedurl-annotatedurl-cpp.html

However:

QtCreator is telling me that Q_NFC_EXPORT is: 
#define Q_NFC_EXPORT Q_DECL_IMPORT

I'm using NDK n18r - clang.
I have added QT += nfc to my Android scope.
I have ran qmake

Has anyone tried this with clang? Does this work?
