Android app development starts with a well-defined product goal and an awareness of device variety. Defining the MVP, choosing an architecture, and mapping essential user flows early helps keep the initial release targeted and minimizes rework as the app scales.

Once the foundation is set, focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting make the app easier to maintain and enhance after it launches on Google Play.
