Android app development starts with a clear goal for the product and awareness of device variety. Establishing the MVP, choosing an architecture, and mapping key user flows early helps keep the initial release focused and minimizes rework as the app evolves.

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