Android app development starts with a definite product objective and awareness of device diversity. Defining the MVP, choosing an architecture, and mapping core user journeys early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify ongoing support and iteration after launching on Google Play.
