EF Core with Android Android Application Folder Structure


In the following picture, we have the complete folder structure of a Xamarin.Android application. We will go through every folder and describe the contents of it, as to get a bit more familiarized with the structure of a Xamarin.Android app.

Let’s look at the items inside the Project to see each folder and its purpose.

Properties

  • It contains the AndroidManifest.xml file that describes all the requirements for the Xamarin.Android application, including name, version number, and permissions.
  • The Properties folder also contains AssemblyInfo.cs, a .NET assembly metadata file. It is a good practice to fill this file with some basic information about your application.

References

  • It contains the assemblies required to build and run the application.
  • If you expand the References folder, you'll see references to .NET assemblies such as System, System.Core, and System.Xml, as well as a reference to Xamarin's Mono.Android assembly.

Assets

  • It contains the files the application needs to run including fonts, local data files, and text files.
  • Files included here are accessible through the generated Assets class.

Resources

  • It contains application resources such as strings, images, and layouts.
  • You can access these resources in code through the generated Resource class.

The Resources directory contains the following folders and a file name.

drawable

  • The drawable directories house drawable resources such as images and bitmaps.

mipmap

  • The mipmap directory holds drawable files for different launcher icon densities.
  • In the default template, the drawable directory houses the application icon file, Icon.png.

layout

  • The layout directory contains Android designer files (.axml) that define the user interface for each screen or Activity.
  • The template creates a default layout called activity_main.axml.

values

  • This directory houses XML files that store simple values such as strings, integers, and colors.
  • The template creates a file to store string values called Strings.xml.

Resource.designer.cs

  • It is also known as the Resource class; this file is a partial class that holds the unique IDs assigned to each resource.
  • It is automatically created by the Xamarin.Android tools and is regenerated as necessary.
  • This file should not be manually edited, as Xamarin.Android will overwrite any manual changes made to it.
