Android app development starts with a well-defined product goal and an awareness of device variety. Establishing the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release targeted and minimizes rework as the app evolves.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting make the app easier to support and refine after the Google Play launch.
