Building Android apps starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps maintain focus for the initial release and minimizes rework as the app scales.

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 ongoing support and iteration after the Google Play launch.
