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

With the foundation established, focus moves to UI coherence, speed, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify support and iteration after the Google Play launch.
