Building Android apps starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user flows early keeps the initial release focused and minimizes rework as the app evolves.
Once the foundation is set, focus moves to a consistent UI, performance, and compatibility across OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
