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

Once the foundation is established, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking practices, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
