Starting Android app development involves a well-defined product objective and awareness of device fragmentation. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps maintain focus for the initial release and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI coherence, speed, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration following the Google Play rollout.
