JavaScript reference for mobile devices?

I'm trying to create a form for use primarily on mobile (Android/iOS). It's a simple enough situation that I'd rather make a fancy PDF, instead of a basic app. Plus, I have a hard requirement that the final dataset be a 8.5x11 PDF. While the PDF must be 8.5x11 on PC and when printed, I'd like to smartly reflow the fields into a specific order on smaller screens. I expect that I may need to use Template Pages to make a "Mobile" version 😥

I've looked for the previous "JavaScript for Acrobat Reader Mobile API Reference", but every single link 404s now.

The biggest hurdle I am facing: Can PDFs be created with a defined reflow, depending on screen size/user agent?

Functions I need (on mobile):

- Text fields with formatting (date, time, number, phone)

- Check boxes

- Drop downs with settable lists

- Button to email the filled form (optional, tbh)

Tools I have:

- Adobe Acrobat Pro

- Adobe AEM Designer 6.5

- Stubbornness
