Starting with a well-defined product objective and awareness of device variety sets the foundation. Clarifying the MVP, choosing an architecture, and mapping essential user flows early keeps the initial release focused and lowers rework as the app expands.

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