AR error on java unity project

November 29, 2013 - 2:12am #1

Hello ,

 

I have creted a java project and then i integrated a unity project into it ,

The unity project contain 2 scenes , one is a normal unity 3D scene and the other is AR scene ,

 

When i open my application on the phone the 3D scene works fine but when i switch the AR scene it opens but no camera (black camera)

In my Logcat output i have some errors from Unity tags and AR tags  :

 

Unity : Could not initialize the tracker

Unity :(Filename : ./Runtime/ExportGenerated/AndroidManaged/UnityEngineDebug.cpp Line 54)

Unity : Data set does not exist

AR : Failed to set hint "HINT_MAX_SIMULTANEOUS_IMAGE_TARGETS' because The Image Tracker has not been Initialized

AR: CameraDevice getCamera calibration() : Failed to get Camera calibration because the camera is not initialized

 

...; please i need help on this problem i have spent a lot of time trying ... but nothing changed :/

Hello, 
 
I wanted to know if you find the solution of the problem? I currently have the same issue and despite the number of post I read, I can not resolve the error Unable to find QCARWrapper. 
 
Thank you in advance

If you integrate with an Android project, you may want to have a look at these articles, which explain two possible approaches to Unity - Android integration:

https://developer.vuforia.com/resources/dev-guide/extending-unity-android-activity-and-adding-custom-views-eclipse

https://developer.vuforia.com/resources/dev-guide/unity-android-plugins

I hope this can help.

hello Allessandro thanks for replying my question ,

the strange thing in this problem is that the .apk  file exported directly from unity works fine ,

only when i try to integrate the java project with another java android project i get black camera screen (buttons still visible) ...

Hi, the scenario you describe should work without issues;

what happens if you only have the scene with the ARCamera in your project ? have you tried any of the Vuforia samples ? do they work ?
