Android app development starts with a well-defined product goal and awareness of device variety. 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 UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting help support and iterate the app more easily after it launches on Google Play.
