Starting Android app development requires a well-defined objective and awareness of device fragmentation. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps maintain focus for the initial release and minimizes rework as the app evolves.

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