Starting with a clear product goal and awareness of device variety sets the stage for success in Android app development. Defining the MVP, choosing an architecture, and outlining primary user flows early help keep the initial release focused and minimize 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, careful networking, and dependable analytics and crash reporting simplify support and iteration after the Google Play launch.
