Android app development starts with a well-defined goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps maintain focus for the initial release and minimizes rework as the app evolves.

Once the foundation is established, focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
