Starting Android app development with a well-defined product objective and awareness of device diversity sets the direction. Defining the MVP, 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 established, focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics and crash reporting simplify maintenance and iteration after releasing on Google Play.
