Sample fails on iOS

By kalugny on Thu, 11/07/2013 - 11:02

Hi,

I am running the Image Targets Unity Extension sample on an iPad, and when reaching scene 4 (the scene that actually have the AR stuff), it shows a dialog saying "Failed to initialize QCAR" and closes.

The log says:

<pre>

trackerManagerInitTracker Error: Image Tracker could not be initialized. Could not initialize the tracker. UnityEngine.Debug:Internal_Log(Int32, String, Object) UnityEngine.Debug:LogError(Object) TrackerManagerImpl:InitTracker(Type) (at /Users/ilang/test/Assets/Qualcomm Augmented Reality/Scripts/Internal/TrackerManagerImpl.cs:67) DataSetLoadBehaviour:Start() (at /Users/ilang/test/Assets/Qualcomm Augmented Reality/Scripts/DataSetLoadBehaviour.cs:52)   (Filename: /Users/ilang/test/Assets/Qualcomm Augmented Reality/Scripts/Internal/TrackerManagerImpl.cs Line: 67)
</pre> As far as I can tell, I followed all the instructions to the letter. I am using:Unity Pro (with iOS Pro) - 4.2.2f1and the latest xCode - 5.0.1. Can you please assist me? Thank you very much,  Yuval Kalugny

Hi

Just a few questions to try and narrow down:

  • Is this the Image Targets sample out of the box? or have there been any changes?
  • Which version of Vuforia is it?
  • Which iPad version is it?
  • Which iOS version is it?

 

  • This is the sample out of the box, no changes - just a new project and the unitypackage import.
  • Latest - 2.6.7
  • iPad 3rd Gen, software version 6.1.3

I don't have any other iOS devices, so I haven't tried running on other devices.

I don't know why it is not working.

One thing you could try is just building it with scene 4 and then debugging through XCode to see what the log says.  Maybe it might display why the tracker has failed to initialise?
