Starting Android app development requires a clear product goal and awareness of device diversity. Defining the minimal viable product, choosing an architectural approach, and outlining key user flows early helps keep the initial release focused and minimizes rework as the app evolves.

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