Android app development starts with a well-defined objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps maintain a focused initial release and minimizes rework as the app evolves.

Once the foundation is set, focus moves to UI coherence, speed, and compatibility across different OS versions and screen dimensions. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
