Starting Android app development with a well-defined product objective and awareness of device variety sets the foundation. Outlining the MVP, choosing an architecture, and mapping key user flows early keeps the initial release focused and minimizes rework as the app expands.

Once the fundamentals are established, focus moves to consistent UI, performance, and compatibility across OS versions and screen sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
