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

Once the foundation is in place, focus moves to UI consistency, speed, and compatibility across OS versions and various screen sizes. Robust state management, prudent networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
