Android app development starts with a clear product goal and awareness of device diversity. Defining the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release focused and minimizes 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/crash reporting make the app easier to maintain and iterate on after the Google Play launch.
