Building Android apps starts with a well-defined product objective and awareness of device variability. Outlining the MVP, choosing an architectural approach, and mapping key 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 OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify ongoing support and iteration after launch on Google Play.
