E-Commerce Android APK Development

I need a production-ready e-commerce APK for my shop and would like you to walk me through the full build—step by step—before we begin. The inventory I will be listing is “Android developer”-related, so the flow must feel every bit as professional as a tech-service storefront.

Here is what I expect:

• A clean, brand-matching UI that lets customers browse and place orders with zero friction.
• A fully functional APK I can upload directly to Google Play, backed by well-structured, maintainable code.
• An admin space (web or in-app) where I can add, update, or remove offerings without touching code.
• Payment gateway integration that supports at least one mainstream provider.
• Basic analytics hooks so I can track installs, conversions, and repeat buyers.

Please outline:

1. Your development process from kickoff to release (design, builds, QA, deployment).
2. The timeline for each phase with key milestones.
3. Any third-party libraries or frameworks you intend to rely on.

Deliverables will be the signed APK, source code, short setup guide, and anything else you consider essential for a smooth launch.

Once I review your approach and timing, we can lock scope and move forward.
