Android app development starts with a clearly defined goal and an awareness of device fragmentation. Defining the MVP, choosing an architecture, and outlining core user flows early helps keep the initial release focused and minimizes rework as the app grows.

Once the foundation is in place, the focus moves to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and reliable analytics/crash reporting make the app easier to support and iterate on after it launches on Google Play.
