Android app development starts with a well-defined product goal and awareness of device fragmentation. Outlining the MVP, picking an architecture, and mapping essential user flows early keeps the initial release focused and minimizes rework as the app expands.

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