Starting Android app development demands a clear product goal and awareness of device fragmentation. Defining the MVP, choosing an architecture, and mapping essential user flows early on helps keep the initial release focused and minimizes revisiting work as the app evolves.

Once the foundation is in place, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after releasing on Google Play.
