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

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 reliable analytics and crash reporting simplify maintaining and iterating the app after it launches on Google Play.
