Starting with a well-defined product objective and awareness of device variety sets the foundation for Android app development. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release tight and minimizes rework as the app expands.

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