Starting Android app development with a well-defined product objective and awareness of device variety sets the foundation. Clarifying the MVP, choosing an architecture, and outlining key user flows from the outset helps keep the initial release focused and minimizes rework as the app evolves.

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