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

Once the foundation is established, 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 maintain and iterate after its Google Play launch.
