Starting Android app development requires a clear product objective and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping essential user journeys early on keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus shifts to consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting help maintain and iterate the app after it launches on Google Play.
