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

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting facilitate maintenance and iteration after launching on Google Play.
