Starting Android app development with a well-defined goal and awareness of device variability sets the stage. Clearly outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

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