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

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