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

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across different OS versions and display sizes. Robust state management, thoughtful networking, and dependable analytics and crash reporting simplify maintenance and future iterations after the Google Play launch.
