Starting with a well-defined product objective and awareness of device variability is key to Android app development. Outlining the MVP, choosing an architecture, and mapping essential user flows early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus moves to UI coherence, speed, and compatibility across OS versions and display dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play debut.
