Building an Android app starts with a clear product goal and awareness of device variety. Defining the MVP, choosing an architecture, and mapping essential user flows early help keep the initial release focused and reduce rework as the app evolves.

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