Building Android applications starts with a well-defined objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus moves to interface 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 publishing on Google Play.
