Starting Android app development involves a definite 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 cross-version and cross-device compatibility. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
