Building an Android app starts with a well-defined target and awareness of device diversity. Clarifying the MVP, choosing an architecture, and mapping key user flows early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, the focus moves to UI consistency, performance, and ensuring compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
