Building an Android app starts with a definite product objective and awareness of device variety. Defining the MVP, picking an architecture, and outlining key user flows early helps keep the initial release focused and minimizes revisions as the app expands.

Once the foundation is established, focus moves to a consistent UI, speed, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after publishing on Google Play.
