Starting Android app development requires a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping key user journeys early keeps the initial release focused 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 streamline maintenance and iteration after launching on Google Play.
