Starting Android app development with a well-defined goal and awareness of device variety sets the stage. Outlining the MVP, choosing an architecture, and mapping essential user flows early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
