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

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after the Google Play deployment.
