Android app development starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping fundamental user journeys early keeps the initial release tight and lowers rework as the app expands.

Once the foundation is established, focus moves to UI consistency, performance, and compatibility across different OS versions and screen dimensions. Robust state management, careful networking, and dependable analytics/crash reporting help maintain and iterate the app after it launches on Google Play.
