Starting Android app development involves a well-defined objective and awareness of varying devices. 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 UI uniformity, performance, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
