Starting Android app development with a well-defined product goal and awareness of device variety sets the foundation. Clarifying the MVP, choosing an architecture, and outlining key user flows early keeps the initial release focused and minimizes rework as the app expands.

Once the groundwork is established, focus moves to UI coherence, performance, and compatibility across OS versions and screen sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
