Android app development starts with a well-defined objective and awareness of the variety of devices. Outlining the minimum viable product, choosing an architectural approach, and mapping key user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus shifts to consistent UI, better performance, and compatibility across different OS versions and screen sizes. Strong state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
