Vuforia AIR Native Extension

By markovidmar on Tue, 11/20/2012 - 10:13

Hello, everybody. I'm trying to make a Vuforia AIR native extension and have run into a problem.

Java class is similar to the class shown here: http://help.adobe.com/en_US/air/extensions/WS39e706a46ad531be-49badd05132afbce693-8000.html

This class is not an Activity, because I don't want it to be. The rendering of the surface will be done in AIR and not on a SurfaceView.

The java part of the native extension loads the .so files just fine.

The problem I have is with the QCAR.setInitParameters.I'm using the Native Extension context to get an activity for init parameters. 

The app crashes and this is shown in the LogCat:

 Can I make this work?

thanks for the information; that allows me to exclude some possible issues affecting the setInitParameters() in older version of Vuforia when running on ICS.

In your case, everything is fine on that side.

Hard to tell then what can make it fail with AIR;

I did what you suggested. While doing it, I realised I forgot to init mQCARFlags.
Could be a problem I'm not making the calls from an Activity?

Hi, setting the mQCARflags is a fundamental step, as it allows QCAR to know if you are using OpenGL ES 1.1 or 2.0, so you must set it of course before getting to the setInitParmaters.

I tried what you have suggested but it still throws the same error as before.
I guess I won't be able to do what I want with current API.

Hi, the reason for passing the activity parameter to qcar init is that QCAR will store some low-level information on the activity; this is really about low level details of QCAR impleemntation I cannot describe here.

One extra note:

I searched the internet and found many forums discussing a similar crash (signal 11 etc.) occurring with Adobe AIR on Android in various circumstances, here is an example (but you can find many others):

I'm glad someone else is interested in this project. And I've made some progress creating the extension.

Awesome that you have made good progress.  I have been a flash developer/designer for many years now and I had recently started my own AR engine in AS3, but like most others, I have found that it is way too slow to make the calculations on the AIR side.

Since I have hardly programmed in Java, Objective C, just started taking a look at this SDK, and has not done any native extensions, take what I say with a micro grain of salt :P

Guys, great to see that you're making such good progress on the AIR side; I'm following your discussion with interest.

I was unsuccessfully trying to send bitmapdata over jni from java to air. Too damn slow. 1-2 fps. I was so close to giving up, when I tried one last thig.

Hi markovidmar, when you're done with your amazing work, it would be really great if you could post here a complete step-by-step solution (not the whole code, but just the process and a few relevant code snippets where appropriate); that would be very valuable for other possible Adobe AIR + V
