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

With the core framework established, focus moves to UI consistency, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
