I try to make a NFC application with Vuforia unity. To make this i first read these three documents :
So, I wrote a java plugin for unity3d and extends the QCARNativeActivityPlayer to catch nfc events. It works, i can read NFC tag with augmented reality.
But when I flash a tag, the camera turn off for one second. I feel the QCAR activity is put to background while the intent catch nfc event and returns to foreground after.
I would like to get QCAR activity always on top when receive nfc event and don't have blackscreen while the intent manages nfc. But i don't know how to do this.
Can you help me ?
thanks you in advance
