JavaVM - platformNativeInterface - Qt5

[Christophe M]

I'm using Qt5 for android to build a qml application without problems but to be able to call a java method from Qt, I try to get a pointer to the JavaVM and I have this error :

JavaVM* currVM = (JavaVM *)QApplication::platformNativeInterface()->nativeResourceForWidget("JavaVM", 0);

error: invalid use of incomplete type 'class QPlatformNativeInterface'

Without this, application run fine on device.

Any idea ? How can I call a java method from Qt ?

error: QPlatformNativeInterface: No such file or directory

The call comes from QApplication (QApplication::platformNativeInterface())

#include <QPlatformNativeInterface>

QPlatformNativeInterface is a private header.
so you need to include the path to the private headers.

Seems that the qplatformnativeinterface header has changed in Qt 5.1, it doesn't contains nativeRessourceForWidget ..

Is there an other way than implementing a socket communication between Java and Qt to communicate from Qt to Java ?

#include "QtGui/5.1.0/QtGui/qpa/qplatformnativeinterface.h"

error: 'class QPlatformNativeInterface' has no member named 'nativeResourceForWidget'

yeah, it changed.

qApp->platformNativeInterface()->nativeResourceForIntegration("JavaVM")

that's what you want to call. the rest is still the same, i think.
