Starting with a clear product objective and awareness of device variety sets the stage for successful development. By defining the MVP, choosing a system architecture, and outlining key user flows early, the initial release stays focused and minimizes rework as the app expands.

Once the foundation is established, 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 ongoing support and iteration after launching on Google Play.
