Xamarin.Forms - Working with Firebase Analytics

In this blog post, you will learn how to implement Firebase Analytics in Xamarin.Forms mobile app.

Introduction

Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files is most easily done using the native file APIs on each platform. Alternatively, embedded resources are a simpler solution to distribute data files with an app.

Firebase

Firebase gives you functionality like analytics, databases, messaging and crash reporting so you can move quickly and focus on your users.

Firebase is a back-end platform for building Web, Android, and iOS applications. It offers real-time database, different APIs, multiple authentication types and hosting platform. This is an introductory tutorial, which covers the basics of the Firebase platform and explains how to deal with its various components and sub-components.

Build apps with Firebase

1. Real-time Database
2. Storage
3. Notifications
4. Authentication
5. Hosting

Firebase Analytics

Google Analytics for Firebase provides free, unlimited reporting on up to 500 distinct events. The SDK automatically captures certain key events and user properties, and you can define your own custom events to measure the things that uniquely matter to your business.

Start by creating a new Xamarin.Forms project. You wíll learn more by going through the steps yourself.

Visual Studio 2019 has more options in the opening window. Clone or check out the code from any repository or, open a project or solution for your computer.

Now, you need to click "Create a new project".

Now, filter by Project Type: Mobile

Choose the Mobile App (Xamarin. forms) project under C# and Mobile.

Name your app. You probably want your project and solution to use the same name as your app. Put it on your preferred location for projects and click "Create".

Now, select the blank app and target platforms - Android, iOS and Windows (UWP).

Subsequently, go to the solution. In there, you get all the files and sources of your project (.NET Standard). Now, select the XAML page and double-click to open the MainPage.Xaml page.

You now have a basic Xamarin.Forms app. Click the Play button to try it out.

Setting up the User Interface

Go to MainPage.Xaml and write the following code.

MainPage.xaml


NuGet Package

Now, add the following NuGet package in your .Net Standard Project.

• Xamarin.Firebase.Core

Create a Interface IFirebaseAnalytics 

Now, create an Interface in .Net Standard Project.

Write the following code.

IFirebaseAnalytics.cs


Android Implementation

Create a project in Firebase

In this step, create a project in Firebase. Go to the following link.

https://console.firebase.google.com/

Click "Add Project".

Now, give the project a name and select your country. Then, read the terms. Afterward, click "Create project".
