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.

Prerequisites

  • Visual Studio 2017 or later (Windows or Mac)
  • Firebase Account

Setting up a Xamarin.Forms Project

https://github.com/susairajs/XamarinForms_FirebaseAnalytics

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".
Now, your project is ready, click "Continue".

Add Firebase to your Android App

Now Register your android app in firebase with Android package name, app name(optional) and your debuting signing certificate(optional) then click to register app.

Done, now you will get one google-service.json file you should download it.

Now Add google-service.json in your ProjectName.Android Project and set Bundle Action GoogleServicesJson

Add following ItemGroup in your ProjectName.Android.csproj file

NuGet Package

Now, add the following NuGet package in your android project.

  • Xamarin.FireBase.Analytics.Impl

Create class FirebaseAnalytics in android project

FirebaseAnalytics.cs

iOS Implementation

Add Firebase to your iOS App

Now Register your iOS app in firebase with iOS Bundle id, app nickname(optional) and App Store id(optional) then click to register app.

Done, now you will get one GoogleService-Info.plist file you should download it.

Now Add GoogleService-Info.plist in your ProjectName.iOS Project and set Bundle Action Bundle Resource

NuGet Package

Now, add the following NuGet package in your iOS project.

  • Xamarin.FireBase.iOS.Analytics

Create class FirebaseAnalytics in iOS project

FirebaseAnalytics.cs



Note:  Go to Run -> Run With -> Custom Configuration and add the following to Extra mlaunch Arguments:

Finally Add the Click Event in MainPage.xaml.cs



Click the "Play" button to try it out.

Check your app analytics in firebase

Xamarin.Forms - Bottom Tabbed Page using Shell

In this blog post, you will learn how to create a Tabbedpage and sub tabs using shell in Xamarin.Forms.


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.

Shell

Xamarin.Forms Shell reduces the complexity of mobile application development by providing the fundamental features that most mobile applications require. This includes a common navigation user experience, a URI-based navigation scheme, and an integrated search handler.

Prerequisites

  • Visual Studio 2019 (Windows or Mac)
  • Xamarin.Forms 4.0 Updated

Setting up a Xamarin.Forms Project

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.

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

Note : Your Xamarin.forms version should be updated 4.0

Bottom Tabbed Page

This code example is Bottom Tabbed Page

Method #1

AppShell.Xaml



Method #2

AppShell.Xaml


Method #3

AppShell.xaml


Try it out.

Sub Tab view

AppShell.xaml

This code example is Sub Tabbed Page


Click the "Play" button to try it out.

I hope you have understood how to create a Tabbedpage and sub tabs using shell in Xamarin.Forms..
