Starting with a clear product goal and awareness of device variety sets the stage for success. Defining the minimum viable product, choosing an architecture, and outlining key user flows early keeps the initial release focused and minimizes rework as the app evolves.

Once foundational elements are in place, focus shifts to consistent UI, 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 launch on Google Play.
