Starting with a clear product goal and awareness of device fragmentation sets the course for Android app development. Defining the MVP, choosing an architecture, and outlining key user flows early helps the initial release stay focused and minimizes rework as the app evolves.

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