Starting Android app development involves setting a well-defined product objective and acknowledging the variety of devices. Establishing the MVP, choosing an architecture, and outlining key user journeys early helps maintain focus for the initial release and lowers the need for rework as the app expands.

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