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

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