Starting Android app development requires a definite product goal and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping key user flows early help keep the initial release focused and minimize rework as the app evolves.

Once the foundation is set, the focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
