Building Android apps starts with a well-defined goal and awareness of varied devices. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and lowers later rework as the app expands.

Once the foundation is set, focus moves to a consistent UI, 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.
