Starting Android app development with a well-defined goal and awareness of device diversity sets the direction. Outlining the MVP, choosing an architecture, and mapping key user flows early keeps the initial release focused and minimizes rework as the app scales.

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