Resolved Building into Android fails because of the package ARCore XR Plugin

So I wanted to learn how to make AR applications with Unity so after downloading all the packages, it seems that the package ARCore XR Plugin (2.1.12) is giving me error when I build into Android. For reference I am using 2019.4.13f1.

There are lots of things on the console, so I have pasted two which I think might be relevant.


Missing 'package' key attribute on element package at [:arcore_client:] AndroidManifest.xml:30:9-54

UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr) (at /home/bokken/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:197)



Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.

I had the same problem. It seems, that Unity describes Packages as "verfied" but never tested it in real life. I downgrade the package to 2.1.11 via the package manager and it worked again. Hope this solves your problem too.

 

Ok thank you. Now I understand the issue and I'll try it in a separate project before applying to the current.

 

Problem fixed here :
