Android app creation starts from a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys upfront keeps the initial release focused and minimizes rework as the app scales.

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