Android app development starts with a well-defined goal and an understanding of device variety. Establishing the MVP, choosing an architecture, and outlining the main user flows early helps keep the initial release focused and minimizes rework as the app grows.

Once the foundation is in place, focus shifts to UI consistency, performance, and compatibility across operating system versions and screen sizes. Robust state management, careful networking, and reliable analytics/crash reporting make the app easier to support and iterate on after the Google Play release.
