Unable to find FirebaseCppApp-6.2.0

Please describe the issue here:

I’m building for Android, and the app crashes instantly with the DllNotFoundException mentioned in https://github.com/firebase/quickstart-unity/issues/398 and https://github.com/firebase/quickstart-unity/issues/395

I exported the project and noticed that no libraries from firebase are in the libs folder. I did run the newest version of the play services resolver:

This looks good to me. It did however not change my mainTemplate.gradle, if that was supposed to happen? This looks like so:

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'

}

allprojects {
    repositories {
        google()
        jcenter()
        flatDir {

        }
    }
}

I’m building to ARMv7, ARM64 as well as x86. I’m also using .NET4 and the scripting backend is set to IL2CPP.

I’m not very experienced when it comes to the process of turning DLL’s into libs compatible with Android. In which phase is this controlled? That might give me some insight into what is different in this project.

Please answer the following, if applicable:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?

No, the issue couldn’t be reproduced in the quickstarts project. I took the test project, opened the analytics project and fed it the newest (6.2.0) version of Firebase.

Running the resolver in this project actually gives me a bunch of com.google.firebase .aars in my Plugins/Android folder. I’ll try copying them over to my own project and see if that works for now, but it would be nice if the resolver worked in my own project as well!

I already spent hours and hours (every build takes 30 minutes) trying to resolve the issue, so any insight is very appreciated!

We do not use Analytics, so no idea on that front but for the parse SDK you need the special one for .net4x, I just got it from a higher Firebase SDK.
