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 keep the initial release tightly scoped and minimizes rework as the app expands.

With the foundation established, focus moves to a uniform UI, performance, and compatibility across OS versions and device sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify ongoing support and iteration after launching on Google Play.
