Starting Android app development with a well-defined product goal and awareness of device variety is key. Outlining the MVP, choosing an architecture, and mapping core user journeys early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
