Starting with a well-defined product objective and awareness of device variety sets the stage. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is established, focus turns to consistent UI, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration after releasing on Google Play.
