I've set up my project correctly based on the setup documentation, but I'm always getting an object null reference exception on the CrossFirebaseCrashlytics.Current.SetCrashlyticsCollectionEnabled(true); call. Am I missing something in the setup for iOS?

` builder.ConfigureLifecycleEvents(events => {

if IOS

            events.AddiOS(iOS => iOS.FinishedLaunching((_, __) => 
            {
                //CrossFirebase.Initialize(CreateCrossFirebaseSettings());
                CrossFirebase.Initialize();
                FirebaseCloudMessagingImplementation.Initialize();
                try
                {
                    **CrossFirebaseCrashlytics.Current.SetCrashlyticsCollectionEnabled(true);**
                }
                catch { }

                return false;
            }));

else`

Could you please provide a sample project that demonstrates this issue?

I've the same problem here, i'm using .NET8.0 with the following dependencies.

<ItemGroup>
    <PackageReference Include="CommunityToolkit.Maui" Version="7.0.0" />

    <PackageReference Include="Xamarin.Build.Download" Version="0.11.4" />
</ItemGroup>

<ItemGroup Condition="'$(TargetFramework)' == 'net8.0-android'">
    <PackageReference Include="Xamarin.AndroidX.Core" Version="1.12.0.2" />
    <PackageReference Include="Xamarin.AndroidX.Collection" Version="1.3.0.1" />
    <PackageReference Include="Xamarin.AndroidX.Collection.Ktx" Version="1.3.0.1" />
    <PackageReference Include="Xamarin.AndroidX.Activity.Ktx" Version="1.8.0.1" />
    <PackageReference Include="Xamarin.AndroidX.Browser" Version="1.6.0.2" />
</ItemGroup>

And if I uncomment one of these 2 lines it crashes with a null exception on Current object.

@TobiasBuchholz - basically the same thing that @Gius95 has mentioned above

@TobiasBuchholz - I have the same issue as mentioned above. Are there any news about this issue? CorssFirebaseCrashlytics is always NULL in my case ...

Probably I'm encountering the same problem. I have uploaded a simple sample project. https://github.com/iida-i3/FirebaseExperiment

AdamEssenmacher commented 3 months ago

It's not possible for CrossFirebaseCrashlytics.Current to return null.

Please call CrossFirebase.Initialize() during WillFinishLaunching as shown in the basic setup instructions

iida-i3 commented 3 months ago

The exception that I encountered was not CrossFirebaseCrashlytics.Current is null, but seemed to be happening in the following code

Plugin.Firebase.Crashlytics.FirebaseCrashlyticsImplementation.SetCrashlyticsCollectionEnabled(Boolean enabled)

INFO: 2024-06-12 11:04:12.511 FirebaseExperiment.iOS[592:70161] Object reference not set to an instance of an object.

As basic setup, moved the process to WillFinishLaunching and to be no problem.
I updated my sample project. it's not as basic setup, but worked, I'm not sure why.

Lots of strangeness, but I was able to try it anyway. Thanks for the reply.

(P.S.) I was able to try, but still have problem. Specifically, I used version 3.0.0, but it only shows xamarin_find_protocol_wrapper_type. I will continue to look into other Issues, etc. Stacktrace:
