Starting with a well-defined goal and awareness of device variety sets the foundation for Android app development. Clarifying the MVP, choosing an architecture, and outlining key user journeys early helps keep the initial release targeted and minimizes rework as the app evolves.

Once the groundwork exists, focus moves to UI uniformity, performance, 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 launching on Google Play.
