Question

Maybe a language that works well with both platforms.

Answer 1

How good to see a fellow app developer.

I would strongly advise you to follow this guide by the Google themselves:
https://developer.android.com/guide/index.html

Then take it into play to cover the very basics of the idea using Udacity:

When it comes to languages this is the short list:
Android - Java
iOS - Swift
Windows - C#

JavaScript: React Native
Web languages: Ionic
C#: Xamarin

Hope this helped and gosh speed.
