Starting Android app development involves 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 lowers the need for rework as the app evolves.

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