Android app development starts with a well-defined product goal and an awareness of device diversity. Outlining the MVP, choosing an architecture, and mapping core user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is established, 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 support and iteration after the Google Play launch.
