Starting with a well-defined product objective and awareness of device variety sets the foundation for Android app development. Establishing the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release tight and minimizes rework as the app evolves.

Once the core is established, focus moves to UI consistency, responsiveness, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration following the Google Play release.
