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

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