Starting with a precise product goal and an understanding of device fragmentation lays the foundation. Defining the MVP, choosing an architecture, and mapping essential user flows early keeps the initial release focused and minimizes rework as the app expands.

Once the groundwork is set, focus shifts to consistency of the UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics and crash reporting simplify maintenance and iteration after launching on Google Play.
