Unity + Mapbox + ARCore __Colliding plugins error + ARCamera does't activate after importing Mapbox SDK

[cavanju]

I am building an Augmented Reality application where you can place an object when arriving at a specific location.

Importing the Mapbox SDK works fine but the moment I try to build my application I get the following error:

Found plugins with same names, Packages/com.unity.xr.arcore/Runtime/Android/arcore_client.aar and Assets/GoogleARCore/SDK/Plugins/arcore_client.aar. Delete the one of the duplicate plugins.
UnityEditor.AndroidPluginImporterExtension:CheckFileCollisions(String)

UnityEditor.BuildPlayerWindow:BuildPlayerAndRun() (at C:/buildslave/unity/build/Editor/Mono/BuildPlayerWindow.cs:122)

Plugins colliding with each other.

Build completed with a result of 'Failed'

Apparently Android/arcore_client.aar and Assets/GoogleARCore/SDK/Plugins/arcore_client.aar are colliding, the latter is getting imported from Mapbox.

What have I tried

1. I tried disabling the GoogleARCore/SDK/Plugins/arcore_client.aar like shown in the image below:

This made it possible to build the application, however the AR Camera in all of the scenes that use arcore-arfoundation for plane detection and object placement did not activate when starting the scene. Instead, I would get a skybox view.

I have no idea why this happens because it works perfectly before importing Mapbox and the arcore_client.aar that I disabled should not affect this as this was imported together with the Mapbox SDK. My guess is that it stopped working the moment I imported Mapbox and not when I disabled the arcore_client.aar .

2. I tried deleting Android/arcore_client.aar instead of disabling GoogleARCore/SDK/Plugins/arcore_client.aar, which gives a lot of errors.

3. I tried using Wikitude AR camera and plane detection. This works but the tracking is a lot worse than that of Google ARCore so this is not an option.

4. I tried messing with the AR camera options in the inspector, no luck so far. These are the settings that I tried:

I am using Unity 2019.2.21f1. - mapbox-unity-sdk_v2.1.1

Hey there!

I had a similar problem, and I found disabling ALL the .aar files (unchecking the 'Android' check box) in Assets/GoogleARCore/SDK/Plugins/ worked for me. Was able to build to Android successfully with AR camera working.

My setup: Unity 2019.4.28f1 LTS mapbox-unity-sdk_v2.1.1

Installed from Unity Package Manager:

• AR Foundation v4.1.7
• ARCore XR Plugin v4.1.7
• ARKit XR Plugin v4.1.7

See if you have any luck with this.
