Building an Android app starts with a well-defined goal and awareness of device fragmentation. Outlining the MVP, choosing an architecture, and mapping essential user flows 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 OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after releasing on Google Play.
