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

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