Starting with a clear product goal and awareness of device fragmentation is key to Android development. Outlining the MVP, choosing an architecture, and mapping essential user flows early keeps the initial release focused and minimizes rework as the app evolves.

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