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

Once the foundation is set, focus shifts to a cohesive UI, performance, and compatibility across different OS versions and device sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play release.
