Unfortunately I'm still working on a solution but I've found a quite interesting article on how to deal with native methods.

http://java.sun.com/developer/onlineTraining/Programming/JDCBook/jniexamp.html

There they say that you need to generate a header file that provides a method signature that you have to use when implementing native functions.
In our case that would be the Dominoes.h that seems to include all my elements that were "not declared in this scope"

Maybe that's the missing puzzle piece to solve our problem ^__^

Plz let me know if you get it working :3

Hey,

If someone manages to get an event when he clicks on the AR in ImageTargets sample, it would be cool to share idea/code.

Thanks in advance.

This has helped me a lot also. I think I am at the same stage as you actually Balvana. I am just trying to work it out at the moment. In the meantime if anyone has any pointers then they would be most appreciated.

Thanks again for all the help you have provided! :-) 

Thanks, that already helped me alot although I am having a problem here ^^;

I'm trying to integrate the native touch events into Image Targets because that's exactly what I need.
The problem is although I declared and called the touch event in the ImageTargets.java and try to use it now in ImageTargets.cpp
I constantly get compile errors -> various elements in the Java_com_qualcomm_QCARSamples_Dominoes_Dominoes_nativeTouchEvent are not declared in this scope...

Is there something important I might be forgetting?
Sorry for the stupid question ^^; I'm still quite a noob..

Are you using the Android SDK or iOS - EAGLview.mm is for iOS.

For Android, take a look at the native touch event in Dominoes.cpp, line 143.

Java_com_qualcomm_QCARSamples_Dominoes_Dominoes_nativeTouchEvent

..and how this is declared ( line 816 ) and called ( line 821 ) in Dominoes.java.

Thanks!

I am looking around the Dominoes sample and I think I need to find something called EAGLview.mm. I can't seem to find it anywhere. Do you know where it is located?

Check out the Dominoes sample for Android. This demonstrates how to project touches on the screen onto the target, which will enable you to determine if a touch intersects with an object.
