Android app development starts with a well-defined product goal and an awareness of device fragmentation. Defining the minimum viable product, choosing an architecture, and outlining key user flows early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is established, focus shifts to a cohesive UI, 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 the Google Play launch.
