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