Starting with a well-defined product goal and awareness of device variety sets the stage for success. Outlining the minimum viable product, choosing an architectural approach, and mapping key user flows early help keep the initial release focused and minimize rework as the app evolves.

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