Android Login & Shop Integration

I already have a working Android Studio project and I’m ready to improve it in two areas:

1. Login flow
• Replace the current entry screen with a fresh login page that includes a country picker dropdown showing the national flags for Lesotho (+266), South Africa (+27), Eswatini (+268), Tanzania (+255) and Uganda (+256).
• When a user taps a country, its dial code must fill the phone-number field automatically.
• The screen has to be fully coded in Java or Kotlin—no static mock-ups.

2. In-app shop
• Beyond login, I need a product-based shop featuring unlimited item listings, a cart and a checkout flow. Think of a clean catalogue view, add-to-cart button, quantity updates and an order summary screen.

Deliverables
• Updated Android Studio project files (Java/Kotlin)
• Signed APK for quick testing
• Clear build/run instructions so I can compile on my end without extra configuration

I’m on a fixed-price arrangement in the R300–R500 range, with R350 earmarked as the midpoint for a single milestone on acceptance of the working source and APK.

If you’re comfortable wiring up flag pickers, dynamic dial codes and a simple but robust product shop, let’s get started.
