Starting Android app development involves a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping key user journeys early keeps the initial launch tight and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI uniformity, performance, and compatibility across different OS versions and display sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after publishing on Google Play.
