Android app development starts with a well-defined goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps keep the initial launch focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI consistency, speed, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and trustworthy analytics/crash reporting simplify maintaining and iterating the app after its Google Play debut.
