Simple 3-Button Android App

I need an Android app put together quickly—nothing fancy, just a clean, static interface with three buttons on the home screen. Each button should take the user to its own dedicated page (so a total of four simple screens including the landing page). No back-end, no data storage, no external APIs; pure client-side navigation only.

Here is what I have in mind:

• Home Screen – three clearly labeled buttons.
• Page 1, Page 2, Page 3 – each can hold placeholder text for now so I can drop in final copy later.
• Smooth navigation using standard Android transitions, with the system back button returning to the previous screen.

I’m flexible on Java or Kotlin; Android Studio is fine. I don’t have wireframes, but the layout is straightforward—think of a centered vertical stack of buttons on a light background. If you have a cleaner idea that still keeps it minimal, I’m open.

Deliverables:
1. Complete Android Studio project with well-commented code.
2. Signed APK (or AAB) ready to install for a quick test.
3. Brief read-me explaining where to swap out screen text or button labels.

I’d like this turned around fast, so let me know your earliest delivery window and any clarifying questions.
