Starting Android app development with a well-defined goal and awareness of device variety sets the stage. Identifying the MVP, choosing an architecture, and outlining key user journeys upfront keeps the initial release targeted and minimizes rework as the app expands.

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