Starting Android app development involves a well-defined product objective and awareness of device variability. 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 established, focus moves to UI uniformity, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after deployment to Google Play.
