Unable to get android style for a qwidget application with qt 5.4

As discussed in the mailing list I am not able to get androidStyle working even for a very basic qwidget-based application (just a new QWidget app from creator with just a QPushbutton and a QSlider in the form, all deployment options etc left to default).

If I run the Qt Quick Controls "gallery" then I get the style ok, but as it seems I cannot get it with a widget-based application. I used to load androidStyle from ministro in 5.3.2, but it does not appear anymore in QStyleFactory::keys(), I get only "Windows" and "Fusion"

I have removed all reference to previous qt related applications, including Ministro.

As requested I join a list of files found under C:\qtDev\build-testStyle-Android_for_armeabi_v7a_GCC_4_8_Qt_5_4_0_91c2a8-Release\android-build\libs\armeabi-v7a

Thanks
