Start Android app development with a clear product objective and awareness of device variability. Outlining the MVP, choosing an architecture, and mapping core user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is in place, 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 simplify maintenance and iteration after the Google Play launch.
