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

Once the foundation is set, focus turns to a consistent UI, 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.
