Starting Android app development requires a definite product objective and awareness of device variety. Clarifying the MVP, choosing an architecture, and outlining key user flows early helps maintain focus for the initial release and minimizes rework as the app evolves.

Once the foundation is set, focus moves to a consistent UI, performance, and compatibility across OS versions and screen dimensions. Robust state management, careful networking, and dependable analytics and crash reporting simplify support and iteration after the Google Play launch.
