[REQUIRED] Please describe the issue here:

(Please list the full steps to reproduce the issue. Include device logs, Unity logs, and stack traces if available.)

Steps to reproduce:

Add and configure the Firebase Realtime database.
It works fine in unity editor.
Upon building it for Android, I get the error given below.

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
What's the issue repro rate? (eg 100%, 1/5 etc)
It happens every time I try to build the project for android.
I tried using earlier firebase versions and the Unity 2020.1 versions, but that failed too.

What happened? How can we make the problem occur?

Hi @AgrMayank

This looks like the com.google.firebase:firebase-analytics-unity:7.0.2 and com.google.firebase:firebase-app-unity:7.0.2 libraries were not resolved by EDM4U properly.

First of all, please try to click on Assets > External Dependency Manager > Android Resolver > Force Resolve menu item and see if this resolves your issue.

If not, please provide a bit more information

• Do you have Assets/Plugins/Android/mainTemplate.gradle in your project?
  • If so, did you see anything under Assets/GeneratedLocalRepo/Firebase/m2repository/com/google/firebase/firebase-app-unity/7.0.2/?
  • If not, can you find com.google.firebase.firebase-app-unity-7.0.2.aar under Assets/Plugins/Android?
• Could you provide verbose logging by enabling it in Assets > External Dependency Manager > Android Resolver > Settings menu item and run Assets > External Dependency Manager > Android Resolver > Force Resolve menu item again?

Thank you
Shawn

Hi @chkuang-g

I tried Resolve and Force Resolve multiple times with getting "Resolution Succeeded all the time. But it didn't help.

• Yes, I have the mainTemplate.gradle file.

  • No, that folder isn't there. Attaching the image below for reference.
    
  • It's not here either.

• VerboseEditor.log

@AgrMayank

Ah, ok. There is definitely something odd going on here.

Could you check if the following files exists?

• Assets/Firebase/Editor/AppDependencies.xml. Also, check if it has a section like the following:

    <androidPackage spec="com.google.firebase:firebase-app-unity:7.0.2">
      <repositories>
        <repository>Assets/Firebase/m2repository</repository>
      </repositories>
    </androidPackage>
  

• Assets/Firebase/m2repository/com/google/firebase/firebase-app-unity/7.0.2/firebase-app-unity-7.0.2.srcaar and Assets/Firebase/m2repository/com/google/firebase/firebase-app-unity/7.0.2/firebase-app-unity-7.0.2.pom

If you did not see any of them, please try to re-import .unitypackage(Auth, Database or Installation, any of them should work). Make sure you select every files.

I just try to install 7.0.2 and I am sure those files should be included in the .unitypackage.

Please let us know if this works for you.

@chkuang-g

Yeah, since even reimporting everything multiple times didn't work for me.

Nope, it doesn't exist there. And none of the files there contains those lines related to firebase-app.

Again, not here. The firebase app folder itself is missing.

I tried to import those multiple times over and over, and after the resolution, everything remains the same more or less. Moreover, everything works just fine in Unity Editor itself.

Due to this issue, I was forced to use 3rd part REST API plugins for Firebase.
