[Bug] Not able to build for Android

[calinpavel787]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2020.3.29f1
• Firebase Unity SDK version: 8.10.1
• Source you installed the SDK: .unitypackeage (.unitypackage or Unity Package Manager)
• Problematic Firebase Component: Analytics (Auth, Database, etc.)
• Other Firebase Components in use: Crashlytics, DynamicLinks (Auth, Database, etc.)
• Additional SDKs you are using: None (Facebook, AdMob, etc.)
• Platform you are using the Unity editor on: Windows (Mac, Windows, or Linux)
• Platform you are targeting: Android (iOS, Android, and/or desktop)
• Scripting Runtime: IL2CPP (Mono, and/or IL2CPP)

[REQUIRED] Please describe the issue here:

Steps to reproduce:

Open Unity > Insert keystore password > Build for Android

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
Didn't test with the quick start

What's the issue repro rate? (eg 100%, 1/5 etc)

What happened? How can we make the problem occur?

Thanks for reporting this, @calinpavel787. Using the information you provided, I haven't been able to reproduce the issue so far. Could you try if updating your Unity editor to its latest version (2021.3.2f1 is the latest LTS version) makes any difference? I've used version 2021.3.1f1, so it's possible that an update is needed.

Thank you @paulinon for the support. I updated the project to the version you indicated, but I'm still not able to create an Android build.

Hello, I'm coming back with some good news:

Mainly I think was my fault being very messy with the project: I changed multiple times the branches, updated the Firebase twice, and probably that was it. But I'm glad to let everyone know how I managed to solve this issue:

1. Roll back to 2020.3.29f1
2. Discard all the modifications and open a clean git without unstashed changes
3. Update the Firebase to the latest version (8.10.1 in my case)
4. Restart the Unity Editor and try to build.

Tested building for Android & iOS and everything is fine. If you need further information, I will let this issue open for investigation if needed.

Thanks @paulinon once more for your help.

[paulinon]

Glad to hear that you've resolved the issue, @calinpavel787. That being said, I'll be closing this ticket. Let me know if an issue arises.
