Starting Android app development with a well-defined goal and awareness of device variety sets the foundation. Clarifying the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app evolves.

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