Android app development starts 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 scales.

Once the foundation exists, focus moves to UI uniformity, performance, and compatibility across different OS versions and screen dimensions. Robust state management, careful networking, and trusted analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
