Android app development starts with a well-defined goal and an awareness of device fragmentation. Clarifying the MVP, choosing an architectural approach, and mapping essential user journeys early helps keep the initial release focused and minimizes rework as the app expands.

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 ongoing maintenance and iteration after launching on Google Play.
