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

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