Android app development starts with a well-defined product objective and awareness of device variety. Specifying the MVP, choosing an architecture, and outlining key user journeys early on helps maintain a focused initial release and minimizes rework as the app evolves.

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