first:

in your .pro:
@QT += gui-private@

now in your cpp:
@

#include <QAndroidJniObject>
#include <qpa/qplatformnativeinterface.h>

QAndroidJniObject getMainActivity()
{
QPlatformNativeInterface *interface = QApplication::platformNativeInterface();
QAndroidJniObject activity = (jobject)interface->nativeResourceForIntegration("QtActivity");

if(!activity.isValid())
qDebug()<<"CLASS NOT VALID!!!!!!!!";
else
qDebug()<<"HORRAY!";

return activity;
}
@

I also like to thanks the MontezooM post which helped me to figure out

Why it fails in your case ?
