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

Once the foundation is established, focus moves to consistent UI, performance, and cross-version and screen-size compatibility. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
