Android app development starts with a clearly defined objective and an awareness of device variety. Outlining the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release targeted and minimizes rework as the app grows.

Once the foundation is set, focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state handling, careful networking, and dependable analytics/crash reporting simplify supporting and iterating on the app after it launches on Google Play.
