Augmented Reality for UE4

Hi Axel,

Thank you for posting your solution! I’ll check this and update for the next version.

I recently ran across a packaging issue with Android builds, so I figured I’d share my solution here.

The AndroidThunkJava_UnpackData method in ARToolkitPlugin_APL.xml assumes that the project name is the same as the last element of the android package name (a.k.a. the ‘appname’ in ‘com.mycompany.appname’).
If this isn’t the case, it unpacks /Content/ARToolkit to the wrong place on-device, causing AR initialization to fail during runtime.

So for instance, if you have a project called ‘MyAugmentedRealityApp’ and set its Android Package Name to ‘com.mycompany.MyAugmentedRealityApp’, then your application will work as intended.
If you then change the package name to ‘com.mycompany.augmentedreality’, the app will package and run, but as soon as you try to initialize AR it will fail and complain that it can’t load camera_para.dat.
