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

Once the foundation is established, 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.
