XamarinComponents: Xamarin.Android.Crashlytics error: package io.fabric.sdk.android.services.events

I had to add every package shown in the license acceptance dialog manually. The full list is as follows:

• Xamarin.Android.Crashlytics
• Xamarin.Android.Crashlytics.Answers
• Xamarin.Android.Fabric
• Xamarin.Android.Crashlytics.Beta
• Xamarin.Firebase.Analytics
• Xamarin.Firebase.Analytics.Impl
• Xamarin.Firebase.Common
• Xamarin.Firebase.Core
• Xamarin.Firebase.Iid
• Xamarin.GooglePlayServices.Basement
• Xamarin.GooglePlayServices.Tasks

I then cleaned the solution, closed the solution, reopened it and rebuilt it and it worked. Not sure if the order of those last steps had any effect or not.

I faced with the same problem today. I’m not sure, but probably the reason is that my solution is Xamarin.Forms solution, not a Xamarin.Android (I tried to add Xamarin.Android.Crashlytics to the Android-specific project though). And/or probably because of Xamarin.Firebase.Messaging & Xamarin.GooglePlayServices.Base references that I already had in my project.

Btw, my (workaround) solution is similar to @Lewy-H + @kyluke solutions. I split added references to 4 categories (the order does matter):

1. “Prerequisites”:

Xamarin.GooglePlayServices.Basement
Xamarin.Firebase.Common
Xamarin.GooglePlayServices.Tasks
Xamarin.Firebase.Iid

1. Xamarin.Android.Crashlytics itself.
2. Xamarin.Android.Crashlytics’ dependencies (they were not downloaded automatically, so I added them manually):

Xamarin.Android.Crashlytics.Answers
Xamarin.Android.Fabric
Xamarin.Android.Crashlytics.Beta
Xamarin.Firebase.Core
Xamarin.Build.Download

1. Others: Xamarin.Android.Crashlytics.Core

Installing Xamarin.Build.Download helped me.

I had the same error. I noticed that the xamarin build download cache did not have any fabric-* directory (using windows myself, so it’s in %USERPROFILE%\AppData\Local\XamarinBuildDownloadCache\).

Installed Xamarin.Android.Fabric NuGet package and now the folder is there (including fabric.aar) and project builds.

After that, i got some error at runtime due to missing java class definitions. To get the app working, I also had to manually install Xamarin.Android.Crashlytics.Answers and Xamarin.Android.Crashlytics.Core and Xamarin.Android.Crashlytics.Beta (basically all dependencies if i’m correct) Installing packages created folders for each package in that xamarin build download cache directory.

Today, installing only Xamarin.Android.Crashlytics, I have the same problem

@Redth please reopen this issue or open new one as the problem still occurs if we use only Xamarin.Android.Crashlytics

What version was this resolved in? I’m seeing this issue in version 2.9.4.1.

Me too in same version (latest). I had to do as @vuurbeving did; manually add Xamarin.Android.Fabric, which gave runtime error, then also add Xamarin.Crashlytics.Core, Answers and Beta.
