Starting with a clear product goal and an awareness of device variety sets the stage. Outlining 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 foundation is in place, the focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
