Starting with a well-defined product objective and awareness of device variety sets the course for Android app development. Identifying the MVP, choosing an architecture, and outlining key user journeys early helps maintain a focused initial release and minimizes rework as the app expands.

Once the foundation is established, focus moves to consistent UI, performance, and cross-version and cross-device compatibility. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify ongoing support and iteration following the Google Play launch.
