Building Android apps starts with a well-defined product goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps keep the initial release focused and minimizes rework as the app evolves.

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