Starting with a definite product objective and awareness of device variety sets the foundation for Android development. Outlining the MVP, choosing an architectural approach, and mapping key user journeys early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI uniformity, performance, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
