Starting with a well-defined goal and awareness of device variation sets the foundation for Android app development. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI cohesion, speed, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration post-launch on Google Play.
