In this chapter, we focused primarily on how to develop a native Android app using Visual Studio for Mac, Xamarin.Android, and C#. You learned how to use and work with the Visual Designer in the Visual Studio for Mac IDE to construct the user interface for your PhotoLibrary app using XML and implement Material Design in your apps, as well as create your own custom themes and then apply theming to your app.
Finally, you learned how to provide the necessary permissions to AndroidManifest.xml so that we can interact with the device camera and photo album, before launching the app in the Android emulator. In the next chapter, you will learn how to build a tile sliding game using Xamarin.iOS and C#.
