Starting Android app development with a well-defined product objective and awareness of device variety sets the foundation. Establishing the MVP, choosing an architecture, and outlining key user journeys early keeps the initial release targeted and minimizes rework as the app expands.

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