Controlling Android's hardware subsystems via Qt

[anda_skoa]

What I meant is if Qt Android Extras is availabe under open source Qt?

Unless it specifically says that it is only available as an extension in the so called commerical package, then yes.
The open source Qt is the default one.

But that can easily be verified by looking at the code, e.g.:
http://code.woboq.org/qt5/qtandroide...nctions.h.html

I get qmake error:
Project ERROR: Unknown module(s) in QT: androidextras
Why?

Maybe you don't have the module installed.
Did you build yourself or did you use the download for Android development?

Cheers,
