Android app development starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release targeted and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across different OS versions and screen dimensions. Robust state management, careful networking, and trusted analytics/crash reporting simplify support and iteration after the Google Play launch.
