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 flows early helps maintain a focused initial release and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI uniformity, efficiency, and compatibility across OS versions and display sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify ongoing support and iteration following the Google Play launch.
