Starting Android app development involves a well-defined product goal and awareness of device variety. Pinpointing the MVP, choosing an architecture, and mapping essential user flows early keeps 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 OS versions and screen sizes. Robust error handling, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
