Starting Android app development involves a defined product objective and awareness of device variety. Pinpointing the MVP, choosing an architecture, and mapping core user journeys early keeps the initial release focused and minimizes rework as the app scales.

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