Building Android apps starts with a well-defined goal and an appreciation for the variety of devices. Outlining the MVP, choosing an architecture, and mapping core user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is in place, focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration after the Google Play release.
