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

Once the foundation is set, focus moves to 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 the Google Play launch.
