Starting with a well-defined goal and awareness of device variety is key to Android app development. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI consistency, performance, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
