Starting with a well-defined product objective and awareness of device variety lays 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 evolves.

Once the core is established, focus moves to UI coherence, performance, and compatibility across OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after publishing on Google Play.
