Building an Android app starts with a clear product objective and an awareness of device fragmentation. Defining the MVP, choosing an architecture, and mapping essential user flows 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 different OS versions and screen sizes. Robust state management, efficient networking, and dependable analytics/crash reporting simplify ongoing support and iteration after publishing on Google Play.
