Starting Android app development involves a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping key user journeys early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI consistency, performance, and cross-version and screen-size compatibility. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
