Building an Android app starts with a well-defined product objective and awareness of device variety. Pinning down the MVP, choosing a software architecture, and mapping essential user journeys early helps maintain focus for the initial release and cut down on revisions as the app expands.

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