Building Android apps starts with a well-defined goal and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app scales.

Once the foundation is established, focus moves to a coherent UI, performance, and compatibility across OS versions and display sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
