Bug Firebase app creation failed

hello everyone
iam creating an android app using unity and i want to use firebase realtime database
i used the package 10.7
i got some error first about Firebase.Editor.dll it was an error related to IOs so i deleted the file since iam working on android app
the previous error dispears but i still get this
InitializationException: Firebase app creation failed.
Firebase.FirebaseApp.CreateAndTrack (Firebase.FirebaseApp+CreateDelegate createDelegate, Firebase.FirebaseApp existingProxy) (at /home/runner/work/firebase-unity-sdk/firebase-unity-sdk/linux_unity/app/swig/Firebase.App_fixed.cs:2450)
Firebase.FirebaseApp.Create () (at /home/runner/work/firebase-unity-sdk/firebase-unity-sdk/linux_unity/app/swig/Firebase.App_fixed.cs:1954)
FirebaseManagerScript.Start () (at Assets/FirebaseManagerScript.cs:17)

and this is my code

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using Firebase;
4. using Firebase.Database;
5. using UnityEngine;
6.  
7. public class FirebaseManagerScript : MonoBehaviour
8. {
9.     // Start is called before the first frame update
10.     DatabaseReference databaseRef;
11.  
12.     void Start()
13.     {
14.         Debug.Log("Connecting..");
15.         // Initialize Firebase
16.         //Dont use FirebaseApp.DefaultInstance.SetEditorDatabaseUrl
17.        Firebase.FirebaseApp.Create ();
18.         databaseRef = FirebaseDatabase.DefaultInstance.RootReference;
19.  
20.         Debug.Log("Firebase Connected");
21.  
22.         // Attach listener to the desired variable
23.        
24.     }
25. }

 

How to troubleshoot build failures:

First, make a blank project with a single blank scene and prove that it builds successfully.

If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

Until you can build a blank project to the target platform, don't fiddle with anything else.

Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

Most often things that prevent building are third-party libraries such as Firebase.

Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

Android build not building:

Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

https://forum.unity.com/threads/cant-build-for-android.1306098/

Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:

thank you for your response sir
i would ask can i keep my project and open it in another editor or do i need to open a new project in the new editor so firebase can work

 

if anyone would be here looking for a solution i solved this by changing the unity editor

 

You mean changing unity version? (i'm on 2022.3.2 LTS so atm i have no way up since it's the last safe release

 

i had the same error in the 2023.1.5f1 unity editor

 

Hi Guys. I've fixed this issue.
my solution is
1. download lasted sdk Add Firebase to your Unity project | Firebase for Unity (google.com)
2. unzip the downloaded file.
3. install FirebaseInstallations.unitypackage
4. install FirebaseAnalytics.unitypackage
5. download

google-services.json

and

GoogleService-Info.plist

to

Assets/StreamingAssets/

6. call

Code (CSharp):

1.  
2.         FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task =>
3.         {
4.             app = Firebase.FirebaseApp.DefaultInstance;
5.             FirebaseAnalytics.SetAnalyticsCollectionEnabled(true);
6.         });

on Start().

if you have already done this. you can check by Debug events | Google Analytics for Firebase

if the debug receives your analytic log that means it works.

PS. I'm using unity 2021.3.25f1

 

Is there a reason your are calling `FirebaseApp.Create()` directly? As discussed in the documentation, unless you need to change its defaults, the app is already created automatically.

The best way to initialize the app is discussed in the Unity Setup guide and in code looks similar to this:

Code (CSharp):

1. Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {});

Setting up the database has a couple more steps which are explained in depth there.

If you have any more specific questions regarding getting your project to run in editor, build or work on device consult the Build Debug Guide.

 

Thanks bro you save my day.

 

First of all, thank you chin13577, your answer was very helpful.
In addition to what you said, I could say that for me the problem was in wrong location for

google-services.json

, which I placed in

Assets

folder, as Firebase guide said. But after reading your answer and moving that file to

Assets/StreamingAssets/

, it worked.

 

Just Great Detail you did catch. Awesome.
