Android app development starts with a well-defined product goal and awareness of device diversity. Outlining the MVP, choosing an architecture, and mapping essential user flows early helps keep the initial release focused and minimizes rework as the app scales.
Once the foundation is in place, the focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Proper state management, careful networking, and dependable analytics/crash reporting make the app easier to maintain and iterate after the Google Play launch.
