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

Once the foundation is set, focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting make the app easier to maintain and iterate on after it hits the Google Play store.
