Starting Android app development involves a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping essential user flows upfront 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, careful networking, and dependable analytics/crash reporting simplify sustaining and iterating the app following launch on Google Play.
