Xamarin.Forms - Add Android Project In An Existing Project

In this article, you will learn how to add an Android Project in an existing project 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.
 
Prerequisites
  • Visual Studio 2017 or Later (Windows or Mac)

Setting up a Xamarin.Forms Project

 
Start by creating a new Xamarin.Forms project. You’ll 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 - 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.
 
Now, here there are only two platforms (iOS, and UWP).

Add Android Project

 
First, you need to create a new Xamarin.Forms project with Android Platform. There is another way you can directly add an Android project to your existing Xamarin.Forms project. But I found this the best way.

NuGet Packages
