Starting Android app development involves a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps keep the initial release focused and minimizes rework as the app scales.

Once the foundation is set, focus moves to maintaining UI consistency, improving performance, and ensuring compatibility across OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify ongoing support and iteration following the Google Play launch.
