Starting Android app development requires a well-defined product objective and awareness of device variety. Establishing the MVP, choosing an architecture, and mapping essential user journeys early helps keep the initial release targeted and minimizes rework as the app evolves.

Once the foundation is set, focus moves to UI uniformity, speed, and compatibility across OS versions and screen dimensions. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
