Building an Android app starts with a well-defined product goal and awareness of the variety of devices. Articulating the MVP, 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 set, 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 the Google Play launch.
