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

With the groundwork established, focus moves to user interface consistency, speed, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration following the Google Play launch.
