Failed to configure Firebase after update iOS Analytics package to 6.0.4.1

[onurhazar]

I am getting this exception when configuring firebase. It starts throwing after I updated Firebase.iOS.Analytics to 6.0.4.1 (latest version).

Here is the log;

Failed to configure firebase. Error: Objective-C exception thrown. Name: FIRAnalyticsVersionMismatch Reason: Google Analytics for Firebase version (60004000) does not match with Google App Measurement (50500000) version. Please update.

Transfering this soon to iOS repo!

@onurhazar Hey! We've had similar issue with this package. I've came up with a workaround that should get you up and running.

When you try to update Xamarin.Firebase.iOS.Analytics from lower version, let's say 5.5.0 it has reference to GoogleAppMeasurement.framework in "~/Library/Caches/XamarinBuildDownload", the file is in GAppM-x.x.x, where x.x.x is a version of the Google Measurement App framework.

In our case some machines had another project that was using older version of Analytics package, this meant that it was referencing GAppM-5.5.0. When we tried to deploy another project, not related to the first one, it was throwing the same exception. Because this second project was using Analytics 6.0.4, and this package depends on higher version of GAppM.

It looks like maybe something is causing problems during linking of this native references(GAppM), because when there are more present in XamarinBuildDownload, the exception is thrown every time.

Try the following:

1. Install Xamarin.Firebase.iOS.Analytics 6.0.4.1 package in your project.
2. Right click on your project and select Build (Don't use Run button in the top-left corner)
3. Remove Everything from XamarinBuildDownload - it should be empty.
4. Run restore packages in your project.
5. Try to build your project again, using the same method as in step 2.
6. For me, sometimes this build goes through, sometimes it fails. If it fails just restart the VS.
7. Build again, now the exception should be gone.

Sometimes exception is gone, but the app starts and closes immediately if this would happen, clear your project, remove /bin and /obj folders, and remove application from the device or simulator and then try again.

After all this, the project should start.

Just make sure that in ~/Library/Caches/XamarinBuildDownload only one GAppM-x.x.x is present, that's crucial.

@SotoiGhost
Seems like this one is iOS.

[SotoiGhost]

@onurhazar @szymonkalista Can you upgrade to the most recent version of Firebase Analytics and try again? Remember to delete bin and obj folders and XBD cache. Thanks in advance!

[segfaults-behind-you]

@SotoiGhost
Hey,

When I delete bin, obj and XBD cache I am able to use any version of Firebase Analytics Including the newest.

The tricky part, at least for me, was finding out, that I have to delete XBD cache. The message in the exception(same as in @onurhazar case) isn't very helpful, when you are seeing something like this for the first time. I understand that it's coming from native code, so nothing can be done about it.

Trying to pinpoint why we were getting this exception was very frustrating(albeit pretty rewarding :~D).

Could you tell me, why do we have to delete the XBD cache in this case?
I am seeing something like this for the first time.

It would be awesome if something could be done, so that we can use different Firebase Analytics versions without cleaning the XBD cache. If this can't be done, it would be great if this case could be documented somewhere. (Maybe it is documented somewhere? I couldn't find it.) Because getting this bit of information is crucial in this case.

Hello @szymonkalista ,

I have tried your approach and the issue is still present event after all the cache deletion. Additionally, I'm using the latest versions at this point and the issue is still present.

I'm wondering if there is another workaround and/or if this could be related with a "shared project" type? Due to I tried in a new project/solution on a Windows PC and there are no issues with the Google Apis components.

@vhugogarcia

Hey,

I am currently using the newest packages as well.

Please make sure that the exception which is thrown has this message:

Failed to configure firebase. Error: Objective-C exception thrown. Name: FIRAnalyticsVersionMismatch Reason: Google Analytics for Firebase version (60004000) does not match with Google App Measurement (50500000) version. Please update.

version numbers may differ. Just to be sure, that it isn't some other problem.

We are using .net standard instead of PCL in our project, but I don't think this should cause any issues.

I guess something is broken with how this nuget package handles dependencies on a mac os, that's why it does not happen on Windows. To be able to build iOS project, you have to do it on a mac, or on a windows machine connected to a mac.

Please make sure you've properly deleted all the dependencies in XBD folder.

Here you can see how the XamarinBuildDownload looks on my side, note that GAppM-6.4.1 is the only version of GoogleAppMeasurement that is present and FAnlytycs-6.4.1 is the only version of Firebase Analytics. Disregard other packages, they are not related.

You could try again and delete everything from the path, that you can see in the screenshot I've attached.
Try to delete bin and obj folder from your project also.

Then launch VS with your project, wait until nuget packages are restored, check XBD cache again, to make sure another version of GoogleAppMeasurement isn't available there. After that, build and run your iOS project.

Other thing you might try, is to install all the dependencies of the firestore package manually, before you install the firestore package. Then clear the XBD cache again, and try to build.

In my team, we were able to get several people up and running with this workaround.

Hello @szymonkalista ,

I have tired as same you mentioned, but the issue is still exist. I dont know why its not running in my machine.
Really appreciated, if any more methods are there. Thanks in advance!!!

Hi @vhugogarcia Have you fixed your issue? Please post here, if you have new solution

[segfaults-behind-you]

@SotoiGhost Could someone have a look at this again, please? Seems like the workaround doesn't cut it for some people. On my side - we are not experiencing this issue anymore in our projects.

@padmasrisekar Would you be able to a provide sample project that reproduces this issue? I can check whether this happens on my machine while we wait for the response from the maintainers.
