Android app development starts with a clear product objective and awareness of device fragmentation. Defining the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus shifts to a consistent UI, 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 after its launch on Google Play.
