Starting with a well-defined product objective and awareness of device variety sets the foundation. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

Once the core is established, focus moves to UI uniformity, speed, and compatibility across OS versions and devices. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
