Answer 1

1) Android Studio is a notepad. And you write in Java. Or c++. Or something else. Under the ANDROID platform. What you write in - it doesn't matter - eclipse, android studio, sublime, notepad, word - the capabilities of the platform and OS do not change from this.
2) Is the server yours or someone else's?
3) Rest API. If difficult - a simple GET request. The topic of GET requests has repeatedly shone on the toaster - use the search.
