Starting Android app development with a well-defined product objective 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 expands.

Once the foundation is set, focus shifts to UI consistency, performance, and ensuring compatibility across OS versions and screen dimensions. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
