Starting Android app development with a well-defined product goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user flows early helps maintain focus for the initial release and minimizes rework as the app expands.

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