Firebase Setup Prerequisites

Before integrating analytics, you need properly configured Firebase project with platform-specific configuration files.

Firebase Console Setup Steps

Create Firebase Project
- Navigate to Firebase Console
- Click "Create a project" or select existing project
- Enable Google Analytics for the project
Add Platform Applications
- Click "Add app" and select platform (iOS/Android)
- Enter your app's bundle identifier/package name
- Download the configuration files
Enable Analytics Features
- Navigate to Analytics → Dashboard
- Ensure Analytics is enabled for your project
- Configure data retention settings as needed

Required Firebase Configuration Files

Android Configuration:

- File: google-services.json
- Location: Firebase Console → Project Settings → Your Android App
- Contains: API keys, project IDs, and Android-specific configuration

iOS Configuration:

- File: GoogleService-Info.plist
- Location: Firebase Console → Project Settings → Your iOS App
- Contains: Bundle ID, API keys, and iOS-specific configuration

Step-by-Step Integration Process

Step 1: Add Configuration Files to Your Project

First, include the Firebase configuration files in your MAUI project:

<!-- Add to your .csproj file -->
<ItemGroup Condition="'$(TargetFramework)' == 'net8.0-android'">
    <GoogleServicesJson Include="Platforms/Android/google-services.json" />
</ItemGroup>

<ItemGroup Condition="'$(TargetFramework)' == 'net8.0-ios'">
    <BundleResource Include="Platforms/iOS/GoogleService-Info.plist" />
</ItemGroup>

Step 2: Install Required NuGet Packages

Install the Firebase Analytics package for .NET MAUI:

dotnet add package Plugin.Firebase.Analytics --version 3.1.2

Step 3: Configure Firebase in MauiProgram.cs

Implement Firebase initialization in your application startup:

using Microsoft.Extensions.Logging;
using Microsoft.Maui.LifecycleEvents;
using Plugin.Firebase.Analytics;
using Plugin.Firebase.Core;

#if ANDROID
using Plugin.Firebase.Core.Platforms.Android;
using Android.App;
#elif IOS
using Plugin.Firebase.Core.Platforms.iOS;
using Foundation;
using UIKit;
#endif

namespace YourApp
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .RegisterFirebaseServices()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                });

            // Register analytics service for dependency injection
            builder.Services.AddSingleton<IAnalyticsService, AnalyticsService>();

#if DEBUG
            builder.Logging.AddDebug();
#endif

            return builder.Build();
        }

        private static MauiAppBuilder RegisterFirebaseServices(this MauiAppBuilder builder)
        {
            builder.ConfigureLifecycleEvents(events =>
            {
#if IOS
                events.AddiOS(iOS => iOS.WillFinishLaunching((app, launchOptions) =>
                {
                    CrossFirebase.Initialize();
                    return false;
                }));
#elif ANDROID
                events.AddAndroid(android => android.OnCreate((activity, bundle) =>
                {
                    CrossFirebase.Initialize(activity);
                    FirebaseAnalyticsImplementation.Initialize(activity);
                }));
#endif
            });

            return builder;
        }
    }
}

Step 4: Create Analytics Service Abstraction

Implement a service layer for analytics to improve testability and maintainability:

// IAnalyticsService.cs
public interface IAnalyticsService
{
    Task LogEventAsync(string eventName, Dictionary<string, object> parameters = null);
    Task SetUserPropertyAsync(string name, string value);
    Task SetUserIdAsync(string userId);
    Task LogScreenViewAsync(string screenName, string screenClass = null);
}

// AnalyticsService.cs
public class AnalyticsService : IAnalyticsService
{
    public async Task LogEventAsync(string eventName, Dictionary<string, object> parameters = null)
    {
        try
        {
            if (parameters == null)
                parameters = new Dictionary<string, object>();

            await CrossFirebaseAnalytics.Current.LogEventAsync(eventName, parameters);
        }
        catch (Exception ex)
        {
            // Log error but don't crash the app
            System.Diagnostics.Debug.WriteLine($"Analytics error: {ex.Message}");
        }
    }

    public async Task SetUserPropertyAsync(string name, string value)
    {
        try
        {
            await CrossFirebaseAnalytics.Current.SetUserPropertyAsync(name, value);
        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine($"Analytics error: {ex.Message}");
        }
    }

    public async Task SetUserIdAsync(string userId)
    {
        try
        {
            await CrossFirebaseAnalytics.Current.SetUserIdAsync(userId);
        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine($"Analytics error: {ex.Message}");
        }
    }

    public async Task LogScreenViewAsync(string screenName, string screenClass = null)
    {
        try
        {
            var parameters = new Dictionary<string, object>
            {
                { "screen_name", screenName }
            };

            if (!string.IsNullOrEmpty(screenClass))
                parameters.Add("screen_class", screenClass);

            await LogEventAsync("screen_view", parameters);
        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine($"Analytics error: {ex.Message}");
        }
    }
}

Advanced Event Tracking Strategies

Standard E-commerce Events

For apps with purchase functionality, implement standard e-commerce tracking:

// Track purchase events
public async Task TrackPurchaseAsync(string itemId, string itemName, decimal value, string currency = "USD")
{
    var parameters = new Dictionary<string, object>
    {
        { "item_id", itemId },
        { "item_name", itemName },
        { "value", (double)value },
        { "currency", currency },
        { "transaction_id", Guid.NewGuid().ToString() }
    };

    await _analyticsService.LogEventAsync("purchase", parameters);
}

// Track add to cart events
public async Task TrackAddToCartAsync(string itemId, string itemName, decimal value)
{
    var parameters = new Dictionary<string, object>
    {
        { "item_id", itemId },
        { "item_name", itemName },
        { "value", (double)value },
        { "currency", "USD" }
    };

    await _analyticsService.LogEventAsync("add_to_cart", parameters);
}

User Engagement Metrics

Track key user engagement indicators:

// Track feature usage
public async Task TrackFeatureUsageAsync(string featureName, Dictionary<string, object> additionalData = null)
{
    var parameters = new Dictionary<string, object>
    {
        { "feature_name", featureName },
        { "timestamp", DateTimeOffset.UtcNow.ToUnixTimeSeconds() }
    };

    if (additionalData != null)
    {
        foreach (var kvp in additionalData)
            parameters[kvp.Key] = kvp.Value;
    }

    await _analyticsService.LogEventAsync("feature_used", parameters);
}

// Track user sessions
public async Task TrackSessionStartAsync()
{
    var parameters = new Dictionary<string, object>
    {
        { "session_id", Guid.NewGuid().ToString() },
        { "app_version", AppInfo.VersionString },
        { "platform", DeviceInfo.Platform.ToString() }
    };

    await _analyticsService.LogEventAsync("session_start", parameters);
}

Custom Dimensions and Metrics

Implement business-specific tracking:

// Set user properties for segmentation
public async Task ConfigureUserPropertiesAsync(User user)
{
    await _analyticsService.SetUserPropertyAsync("user_type", user.Type);
    await _analyticsService.SetUserPropertyAsync("subscription_tier", user.SubscriptionTier);
    await _analyticsService.SetUserPropertyAsync("registration_date", user.RegistrationDate.ToString("yyyy-MM"));
    await _analyticsService.SetUserIdAsync(user.Id.ToString());
}

// Track business-specific events
public async Task TrackBusinessEventAsync(string eventCategory, string eventAction, string eventLabel = null, long? value = null)
{
    var parameters = new Dictionary<string, object>
    {
        { "event_category", eventCategory },
        { "event_action", eventAction }
    };

    if (!string.IsNullOrEmpty(eventLabel))
        parameters.Add("event_label", eventLabel);

    if (value.HasValue)
        parameters.Add("value", value.Value);

    await _analyticsService.LogEventAsync("business_event", parameters);
}

Common Issues and Solutions

Issue 1: "Default FirebaseApp is not initialized" Error

Solution: This occurs when Firebase can't find or load your configuration. Fix it by:

1. First: Verify your ApplicationId in .csproj exactly matches the package name in google-services.json
2. Then: Delete bin and obj folders from your project
3. Finally: Clean and rebuild your project

Issue 2: NuGet Package Installation Fails (Long Path Issue)

Solution: Firebase packages can cause path length issues on Windows. The complete workaround is described here: Long Path Issue Solutions
