On November 15, the Fabric SDK and old versions of the Crashlytics SDK will stop sending crashes. To keep getting crash reports, make sure you upgrade to the latest version of the Firebase Crashlytics SDK (v17.0.0+ for Android, v4.0.0+ for iOS, or v6.15.0+ for Unity).

Steps after migrating from Fabric

Welcome to Firebase!

Now that you've migrated your app to Firebase, here are a couple things you'll want to learn about and set up for Firebase:

What happened when you migrated?

For the apps that you linked, your Crashlytics data now appears only in the Firebase Crashlytics dashboard. The linking process does not involve any changes to the legacy Fabric SDK.

If you haven't already, upgrade to the Firebase Crashlytics SDK (the official SDK for Crashlytics). To view crash-free user metrics, make sure to add Google Analytics to your project as well.

For migrating Unity apps to Firebase, follow the Unity migration instructions and review the Unity API changes.

Discover Firebase Crashlytics

Find all your Crashlytics data in the Firebase Crashlytics dashboard (in the Firebase console).

Firebase Crashlytics offers several new features:

How Google Analytics helps Crashlytics

Google Analytics is Firebase's analytics engine that gives you access to powerful insights into your data. Google Analytics lets you set custom and predefined events, similar to Fabric's Answers. When you start using Analytics, you unlock new capabilities in addition to features you were already using in Fabric:

How do I start using Analytics?

Visit the Start using Google Analytics help page to learn how to install and initialize the SDK in your iOS or Android app. After you add Analytics to your app, visit the Google Analytics documentation to start setting up events.

If you have a Unity app, read about getting started with Analytics and logging events in Unity instead.

Keep the following in mind:

  • After you initialize the Google Analytics SDK in your app, there can be a delay of a few hours before data appears in the Firebase Crashlytics dashboard.

  • Firebase can only use analytics data collected by Google Analytics. So, for your migrated apps, your historical analytics data from Fabric Answers cannot migrate to Firebase.

    • Unlike your crash data, your analytics data will start from a blank slate and the Firebase console will only show data collected after installing and initializing the Google Analytics SDK.

    • After you switch your Answers events to Google Analytics events, we recommend removing your Answers events from your app's code.

Monitor your Latest Release

With Google Analytics initialized in your app, you can monitor the stability and metrics of your current builds in the Latest Release page in the Firebase console.

Access the Latest Release page a couple different ways:

Configure your notification settings

Now that you've migrated, you'll start getting emails from Firebase. To configure your notification settings:

  • Visit Firebase alerts (in the top-right corner of the Firebase console) to manage your Firebase alert subscriptions for Crashlytics.

  • For integrations, visit Project settings > Integrations to set up notifications for Jira, Slack, and PagerDuty.

Invite your team members

Now that you've migrated to Firebase, invite your team so that they can start using Firebase and access your migrated app in the Firebase console.

From the Firebase console, visit Project settings > Users & permissions to add teammates as members of your Firebase project.
