Migrating Crashlytics to the Firebase Console

This article was also published on ProAndroidDevSee Here

Last week I setup a project to use Crashlytics for Android as our crash reporting tool.

Use Crashlytics (NEW) and Perf Monitoring to increase app retention and keep users happy! #FirebaseSummit live → https://t.co/eSmn1vZtaf

This week, at the Firebase Dev Summit, support was announced for Crashlytics issue reporting from within your existing Firebase console.

Since I prefer to use as few different service consoles as possible, I wanted to migrate over to the new Firebase Crashlytics reporting.  It was a pretty straightforward process with a couple small gotchas, so I thought I would share what I found.



Starting Point

I started with an app that was configured to use Crashlytics and report to the Fabric console as described here.

To help demonstrate the migration process, I set up a sample project on GitHubThis commit installs the Fabric/Crashlytics kit, and will send crash reports to the Fabric console when a button is clicked.

At this point, the sample app works the same way as the app I had set up last week.



Enable Firebase

If you already have a Firebase enabled app, you can skip down to the next section.

Before you can start receiving crash reports within the Firebase console, you must have a Firebase enabled app.  A more detailed overview of this process can be found here but I’ve included the basic steps below:

Start by clicking “Add another app”

Enter the package name of your app, and an alias if desired

Download the “google-services.json” file and add it to your app’s directory

Add the Firebase plugin to your app



Migrate to Firebase Console

Once you have a Firebase app created, you can migrate over to using Firebase for your crash reporting.

Using the Getting Started docs as a guide, I was able to migrate crash reports by doing the following:

  1. In build.gradle: update the Fabric plugin to version 1.24.4
  2. Add   maven { url "https://maven.google.com/" } to build.gradle
  3. To app/build.gradle add the Firebase sdk: implementation "com.google.firebase:firebase-core:11.4.2"


The first small gotcha was that I then also had to update the google-services plugin to version 3.1.2Commit Here

At this point, I was able to deploy the app, but my crash reports were still not showing up in the firebase console.

The 2nd gotcha was that I seemingly needed to remove the api key meta-data from the app’s Manifest.xmlCommit Here

Once I removed that and redeployed, the crash reports started coming through in the Firebase console.  Hooray!

The full migration changes can be found in this commit.

The Crashlytics view within the Firebase console


I’m now happily using Crashlytics and collecting/analyzing crash reports from within our Firebase console.

I’m probably a little too excited about having #crashlytics as a part of #Firebase now But it felt good to open up that new console today 😀
