NFC implementation on Android using Qt

I'm trying to read the UID from nfc card on Android using Qt. aOn one hand, After some research, I found this class in Java for the reading. On the other hand, I've read on Qt documentation how to call and static Object from Java using QAndroidJniObject::callStaticObjectMethod, but I have no idea how to create an activity using Qt's module AndroidExtras, and make it notify when a new Intent is launch.

Does anyone have some advice to get it work? Thanks in advance,
