Answer 2

You cannot (really). You'll need some basic XML for the layout and some other files that determine how everything gets packaged (like the manifest). The programming itself can be done mostly in Java, but you'll still need to learn about the Android framework and how to create activities, etc. All of that info is on the website for Android and using Android Studio will help greatly.
