I am new to android app development and a friend recommended me to use Xamarin. So I went to go check it out and I installed Xamarin + Visual Studio 2017. After that, I went through some tutorials of how to work with it and making your first app. However, I couldn’t do that as this happened:
I don’t exactly know what to do from here. I checked many other tutorials but they didn’t seem to help. Can anyone here show me how I can fix this problem?
Your question is pretty much self explanatory, you need to set there three “variables” in Visual Studio options.
Here you can see what my (and default) paths looks like.
Also best tutorial for Xamarin installation on Windows is Xamarin official one from their documentation, here you can find all info that you need.
If you don’t have these folder and files you need to install missing ones.
Android SDK (Note: On this page you can download url for Android SDK)
However if you follow the official Xamarin tutorial, from that I provided above I think that you will have everything that you need.
