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

Once the foundation is established, focus moves to user interface consistency, performance, and compatibility across different OS versions and display sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration following the Google Play release.
