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 targeted and minimizes rework as the app expands.

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