Beginning with a well-defined product objective and awareness of device variety sets the direction. Outlining the MVP, choosing an architecture, and mapping key user flows early keeps the initial release targeted and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
