Starting Android app development requires a well-defined objective and awareness of device variety. Pinpointing the MVP, choosing an architectural approach, and outlining key user journeys early keeps the initial release focused and minimizes rework as the app expands.

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