Starting Android app development involves a well-defined product goal and awareness of device diversity. Outlining the MVP, selecting an architecture, and planning core user flows early helps keep the first release focused and minimizes rework as the app grows.

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