How to develop an android app using .Net Core 1.0? [closed]

Question

I know that .Net Core 1.0 is new released and is cross-platform.

Before deciding to go with .Net Core I want to clarification about how to do. I couldn't get satisfying information unfortunately.

So if I want to develop an android app using .Net Core 1.0, do I have to use Xamarin?

If so, how can I make connection with Xamarin while using .Net Core?

And .Net Core app can run on Windows, Mac or Linux but Xamarin apps cannot run on Linux. So as a result can my android app run on all platforms?

Thanks in advance.

AS A RESULT:

As @LexLi and @swick said:

"If you write a library that targets .NET Standard Library, you will be able to use it from .Net Core, Xamarin and .Net Framework"

Answer 1

.Net Core 1.0 supports Windows, OS X and Linux, it does not support Android. So, if you want to write Android app, use Xamarin.
