Starting Android app development requires a well-defined product objective and awareness of device fragmentation. Clarifying the MVP, choosing an architecture, and mapping key user flows early keeps the initial release focused and minimizes rework as the app evolves.

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