Building Android apps starts with a precise goal and awareness of the variety of devices. Outlining the MVP, choosing an architecture, and mapping essential user flows from the start helps keep the initial release focused and minimizes rework as the app expands.

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