Android app development starts with a well-defined product goal and an awareness of device variety. Outlining the MVP, choosing an architecture, and mapping core user flows early keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to consistent UI, performance, and compatibility across OS versions and screen sizes. Robust state handling, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
