Android app development starts with a well-defined product goal and awareness of device fragmentation. Establishing the MVP, choosing an architecture, and mapping core user journeys early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is laid, focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, efficient networking, and dependable analytics/crash reporting simplify maintenance and iterations after launching on Google Play.
