Starting Android app development with a defined product goal and awareness of device variety is essential. By outlining the MVP, choosing an architecture, and mapping essential user flows early, you keep the initial release focused and minimize rework as the app evolves.

Once the foundation is set, focus shifts to UI consistency, performance, and ensuring compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics and crash reporting simplify maintenance and iteration after launching on Google Play.
