Starting Android app development requires a definite product objective and awareness of device variety. Establishing the MVP, choosing an architecture, and outlining key user flows early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus moves to UI cohesion, performance, and compatibility across OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
