Starting Android app development involves a well-defined product objective and awareness of device variety. 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 consistency, performance, and compatibility across OS versions and display sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration after the Google Play launch.
