Building an Android app starts with a well-defined product objective and awareness of device variability. Outlining the MVP, choosing an architectural approach, and mapping essential user journeys early helps keep the initial release focused and minimizes rework as the app expands.

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