Starting Android app development with a well-defined product goal and awareness of device fragmentation sets the foundation. By defining the MVP, choosing an architecture, and mapping key user flows early, the initial release stays focused and minimizes rework as the product evolves.

Once the foundation is in place, the focus moves to consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics and crash reporting help support and iterate the app more easily after it goes live on Google Play.
