Starting with a precise product goal and awareness of device variety sets the stage for success. Defining the MVP, choosing an architecture, and mapping essential user flows early keeps the initial release focused and minimizes rework as the app expands.

Once the groundwork is laid, 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 launching on Google Play.
