在运行时为 Analytics logEvents 初始化 Firebase 不起作用

Question

I have an app that needs 2 Firebase projects. Depending on the login option used, i need to logEvents to a specific Firebase project.

I cannot use multiple google-services.json in different directories based on build variant/flavor because it needs to be one app. As such, i

1. Deleted google-services.json from the project

2. commented apply plugin: 'com.google.gms.google-services' in gradle

3. Initialized Firebase with below code using values from google-services.json file

    val firebaseOptions = Builder().setApplicationId("client.client_info.mobilesdk_app_id").setApiKey("client.client_info.current_key").setDatabaseUrl("project_info.firebase_url").setGcmSenderId("project_info.project_number").setStorageBucket("project_info.storage_bucket").setProjectId("project_info.project_id").build() FirebaseApp.initializeApp(context, firebaseOptions, "[DEFAULT]")

I'm getting below error though.

E/FA: Missing google_app_id. Firebase Analytics disabled.
E/FA: Uploading is not possible. App measurement disabled

Is there a way to solve this issue? I need to initialize Firebase at runtime after a user action and logEvents to Firebase

I think what you are trying to achieve is not possible, I dig around a little bit more, and the experience you are getting is the expected behavior: Analytics does not work with builder (custom) initialization .

You can check a statement from the firebase support team here: Unable to make Firebase work for a non Gradle build: Missing google_app_id. Firebase Analytics disabled

Yet, I discovered this two workarounds on a thread on GitHub, but they do not apply to your use case since it's done at compilation time.

I suggest you to move your analytics to another provider in case this is a stopper for you, or just leave analytics on a single project and add an attribute to differentiate between user/flows.
