Android app development starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps maintain a focused initial release 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 sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
