Android app development starts with a well-defined product goal and an awareness of device variety. Outlining the MVP, selecting an architecture, and mapping core user flows early helps keep the initial release focused and minimizes rework as the app grows.

Once the foundation is set, the focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state handling, careful networking, and dependable analytics/crash reporting make the app easier to support and iterate on after the Google Play launch.
