Android application development starts with a well-defined objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys from the start helps maintain a focused initial release and minimizes later rework as the app expands.

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
