Android app development starts with a well-defined product goal and awareness of device variety. Specifying the MVP, choosing an architecture, and outlining primary user flows early helps keep the initial release focused and minimizes rework as the app expands.
Once the foundation is established, 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 simplify maintenance and iteration after the Google Play launch.
