Starting Android app development requires a well-defined product objective and awareness of the variety of devices. Clarifying the MVP, choosing an architectural approach, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app evolves.

With the foundation set, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after publishing on Google Play.
