Android app development starts with a well-defined product objective and awareness of device fragmentation. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps keep the initial release targeted 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, prudent networking, and dependable analytics/crash reporting streamline maintenance and iteration after the Google Play launch.
