Starting Android app development with a well-defined goal and awareness of device variety is essential. Outlining the MVP, choosing an architecture, and mapping key user flows early keeps the initial release focused and minimizes iterations as the app expands.

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