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

Once the foundation is set, focus moves to a consistent UI, 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 publishing on Google Play.
