Starting Android app development requires a definite product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user flows early helps keep the initial release targeted and minimizes rework as the app expands.

Once the foundation is in place, emphasis turns to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting make the app easier to support and iterate after its Google Play launch.
