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

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