Starting Android app development involves a clear goal for the product and awareness of device fragmentation. Outlining the MVP, choosing an architecture, and mapping essential user flows early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus shifts to consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
