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

Once the foundation is set, focus moves to UI consistency, 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 the Google Play launch.
