My application works on Editor and Connects to my database. Although when i am trying to build in android i get :

java.lang.RuntimeException: Duplicate class android.support.v4.app.INotificationSideChannel found in modules classes.jar (:androidx.core.core-1.0.0:) and classes.jar (:support-compat-25.1.0:)

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

followed by 400errors about :

Duplicate class android.support.v4.app.INotificationSideChannel$Stub found in modules classes.jar (:androidx.core.core-1.0.0:) and classes.jar (:support-compat-25.1.0:)

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

I have already tried to fix with android resolver.

Any idea ?

Hi @tpaslou

I think the issue is the Mapbox package includes legacy Android support library.
See Assets/Mapbox/Core/Plugins/Android/support-compat-25.1.0.aar in your project folder.
As a result, it conflicts with the newer version of the support library, AndroidX, which ARCore and Firebase depends on. And since Google Play Services requires AndroidX now, it is a very bad idea for a SDK provider to ship with legacy support library, instead of using Play Services Resolver, which helps to resolve the reference and dependency for you. And you will need to do all the work to migrate to AndroidX.

I would recommend you to file a bug to Mapbox and recommend them to utilize Play Service Resolver to specify Android dependencies.

Or you can use Map Unity SDK, which depends on AndroidX as well. You might need to contact Google Map team for API key and full version of SDK.

If none of these avenues works for you, you would need to make a AndroidDependencies.xml file for Mapbox. I would recommend you to consult with Mapbox team for more detail but the general idea is:

1. Delete support-compat-25.1.0.aar
2. Create a dependencies.xml like this.
3. Use Force Resolve from Android Resolver, which utilize Jetifier to resolve reference and dependencies for you.
   Assets > Play Services Resolver > Android Resolver > Force Resolve

Hope this helps!
