Starting Android app development involves a well-defined product objective and awareness of device variety. By outlining the MVP, choosing an architecture, and mapping key user flows early, you keep the initial release focused and minimize rework as the app evolves.

Once the foundation is established, focus moves to UI uniformity, performance, and compatibility across different OS versions and display sizes. Robust state management, prudent networking, and dependable analytics/crash logging simplify maintenance and iteration after publishing on Google Play.
