Building Android apps starts with a well-defined goal and awareness of the range of devices. Pinpointing the MVP, choosing an architecture, and outlining essential user flows early keeps the initial release focused and minimizes modifications as the app evolves.

Once the foundation is set, focus moves to consistent 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.
