Building Android apps starts with a well-defined goal and awareness of device fragmentation. Outlining the MVP, 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 UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration after releasing on Google Play.
