Starting with a clear product objective and awareness of device variety sets the foundation for Android app development. By outlining the MVP, choosing an architectural approach, and mapping essential user journeys early, the initial release stays focused and minimizes rework as the app scales.

Once the foundation is established, 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.
