Android app development starts from a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early keeps the initial release targeted and minimizes rework as the app expands.
Once the foundation is established, focus moves to UI consistency, performance, and compatibility across OS versions and screen dimensions. Robust error handling, prudent networking, and dependable analytics/crash reporting simplify ongoing support and iteration after the Google Play launch.
