Building Android apps starts with a definite product objective and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping key user journeys early keeps the initial release focused and minimizes future rework as the app expands.

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