Starting with a clear product goal and an awareness of device diversity sets the foundation for Android app development. Outlining the MVP, choosing an architecture, and mapping key user flows early helps keep the initial release focused and minimizes rework as the app grows.

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