Starting with a clear product goal and awareness of device variety sets the foundation for Android apps. Outlining the MVP, choosing an architecture, and mapping key user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is in place, focus turns to UI consistency, 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.
