I was doing the project using vuforia native on android studio where the native api was called by JNI-C++ and then called by java-android, I want to get notification on android layer when the vuforia detects/loses the image target. 

I found out that on Unity API, we get the event of "OnTargetStatusUpdated" under "ObserverBehaviour" class which we can subscribe our own function to thus we can get the status when the observer status changed.

Hello,

I'm developing AR application for Epson BT-35E smart glasses. I wrote external camera driver and can find image coordinates on top of video stream. Now I need to find target coordinates in see-through mode and place a marker on object in real world. As I understand I need to go through camera calibration procedure and use the result of this procedure in external camera driver.

Hello everyone

I have been working with the sample provided by Vuforia for android studio, but I need to change the model and the target . I've tried changing the assets, and moving some things in AppController.cpp and GLESrenderer.h, but I can't get it to work.

Any ideas or know of an article that can help me?
