Starting Android app development requires a well-defined product objective and awareness of device variety. Pinpointing the MVP, choosing an architecture, and mapping essential user flows early helps keep the initial release targeted and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI consistency, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and future iterations after publishing on Google Play.
